In this blog, I’ll walk you through the different aspects of a softswitch – what is a softswitch, how does softswitch work, class 4 vs class 5 softswitch along with some real-world use cases. I’ll also introduce you to our powerful softswitch products i.e. REVE Session Border Controller (Class 4 Softswitch)  and iTel Switch (Class 5 Softswitch). 

What is a Softswitch?

Softswitch is short for Software Switch, which is a core component used in telecom networks for call controlling and signaling as well as processing media streams. In layman’s words, we can define softswitch as a software application that manages the connection between phone calls placed over the internet i.e. VoIP calls. Acting as a bridge, a softswitch directs and controls the flow of voice, data, and multimedia sessions across IP networks. 

How is a Softswitch Different from a Traditional Switch?

The primary role of any switch is to facilitate communication but what makes the modern-day softswitch more versatile? It’s their software-based nature. I will explain this with the help of 3 key aspects as mentioned below:

Hardware vs Software

A traditional switch is a dedicated hardware system that makes use of circuit switching to physically connect calls. This is why traditional switches are also called hardware-based switches or circuit-based switches. These switches require manual configuration for their work. On the contrary, a software-based switch makes use of digital signals to route calls digitally or over IP networks. 

Rigidity Vs Flexibility

The conventional circuit switches get obsolete with time and need additional hardware for working in line within the modern communication landscape. On the other hand, softswitches are quite flexible and offer a wide range of features such as call recording, voicemail, conferencing, etc. 

Expensive vs Cost-effective

Traditional switches are expensive to maintain and upgrade whereas softswitches run on standard infrastructure making them a cost-effective and easier-to-upgrade option. 

How Does a Softswitch Work?

To understand the workings of a softswitch, let’s consider an example. Your phone rings and you pick up the call and start your conversation with the other person on the call by saying Hello. From this very moment, the role of a softswitch comes in and there are several key functions performed by a softswitch. These functions are:

Call Routing

The softswitch makes sure that each call reaches its intended destination following the most optimal route or path. To identify an optimal path, a softswitch considers various factors like network congestion and quality, etc. 

Protocol Conversion

To ensure seamless communication across diverse networks, softswitches convert voice signals from analog to digital and manage protocol conversion that governs the respective communication. 

Call Management

There are 3 key processes handled by Softswitches – Call Setup, Teardown, and Authentication. By overseeing these processes, softswitches ensure quality and security during the communication sessions. 

Softswitch System Architecture

The above image represents a typical setup of a softswitch system. Now, I will take you through the different components of a softswitch, one by one:

Media Gateway Controller: The Brain of the Softswitch

MGC or Media Gateway Controller is responsible for call control and signaling intelligence. From managing call setup, routing, features, and billing along with interactions with other networks – all this is handled by MGC. Furthermore, this key component makes use of protocols like SIP or H.323 to communicate with other softswitches and gateways. 

Media Gateway

It is responsible for the physical media conversion and transmission of voice and data traffic. Media Gateways take instructions from Media Gateway Controllers i.e. MGC and send call status updates.  

Signaling Gateway

SGB or signaling gateway bridges different networks by acting as a translator for signaling protocols. It makes use of various signaling protocols to connect the softswitch with external networks. Furthermore, it is responsible for converting signaling messages between different protocols to maintain interoperability. 

Types of VoIP Softswitch

VoIP softswitches are categorized into 5 main types with each softswitch performing a different functionality. 

Class 1 Softswitches are implemented in international gateways i.e. handle high volumes of long-distance calls across different countries and continents. They are designed for wholesale carriers, managing large-scale traffic between various telecom providers. Class 2 softswitches focus on regional traffic i.e. handling traffic between local carriers. Class 3 Softswitches are often used by ISPs to connect with larger carrier networks or PSTN. 

Now comes the most widely deployed softswitches i.e. Class 4 and Class 5 Softswitches. Let’s understand what these are. 

What is a Class 4 Switch?

Class 4 switches are used for handling long-distance or wholesale VoIP traffic. You can imagine it as a highway for large volumes of call traffic, that efficiently optimizes geographically distant connections. The main perspective behind using Class 4 Softswitches is cost-effective routing and traffic management. Key features offered by class 4 softswitches are:

• Concurrent calls
• Protocol support & conversion
• Intelligent call routing
• Secured firewall
• Easy to use and simple interface

What is a Class 5 Switch?

Class 5 Switches are focused on providing service to end users or subscribers such as residential clients. Class 5 softswitches are mostly used by ISPs or telecom companies to manage local calls. That being so, class 5 softswitches are used to offer smaller volumes of call traffic and offering personalized services to clients. 

• Auto-attendant
• Call forwarding
• Call transfer
• Call waiting
• Caller ID
• Conference calling
• Virtual phone numbers

Class 4 Softswitch vs Class 5 Softswitch

Both classes of softswitches play a significant role in VoIP networks. The difference between class 4 switch vs class 5 switch can be marked based on 2 key areas:

• Focus 

Class 4 softswitches are designed for wholesale carriers and service providers to handle long-distance traffic. On the other hand, Class 5 softswitches cater to end users.

• Volume Handling

Class 4 softswitches specialize in handling high call volumes across geographically diverse locations also called interexchange VoIP traffic. In contrast, Class 5 Softswitches handle smaller yet diverse call traffic within a specific geographic area. 

To understand the difference between the two softswitches in a better way, I have created this comparison table. Take a look:

Benefits of Using Softswitches

Businesses and organizations around the world have observed several benefits of using softswitches. 

• Scaling Up and Down is Easy

Softswitches offer incredible scalability. Because softswitches run on software, adding more calls doesn’t require any type of physical expansion. Softswitches facilitate scaling up and down virtually. 

If you wonder who can benefit from this scalability of softswitches then startups, call centers, cloud providers, etc., are a few businesses. The scalability of softswitches can help such businesses adapt to changing business needs. 

• High Reduction in Cost

When compared to traditional circuit-based switches, softswitches come out to be quite pocket-friendly. Since there is no additional hardware to be purchased for the working of softswitches, companies save a lot of money. Even when there’s a need to upgrade, softswitches allow so without any heavy investment. 

• Automate Accurate Billing

Traditional switches relied on manual billing which is prone to errors. However, modern-day softswitches have automated the whole process as they come with built-in billing solutions. Softswitches are capable of tracking call details in real-time with laser precision and apply pre-configured billing rules to calculate tariffs and generate accurate invoices. 

Beyond billing accuracy, softswitches offer a lot of convenience and add efficiency to the overall communication process. Both businesses enjoy faster and transparent invoicing which ultimately builds the trust of the customers. Mobile operators leverage softswitches to ensure accurate billing of prepaid, postpaid, data usage, and roaming charges. 

• High Versatility

It won’t be an overstatement if I say that a softswitch is a universe of possibilities. Don’t believe it? Let me explain. 

The first reason for the above statement is that Softswitches handle Multiple Services under One Roof. From voice calling, video conferencing, and instant messaging to unified communications platforms – Softswitches can handle them all. 

Secondly, softswitches can seamlessly adapt to any technology be it VoIP, traditional PSTN, or a combination of both. This adaptiveness of softswitches makes them a universal element of the telecommunication world. 

Last but not least, modern-day softswitches come like a tailor-made suit for your communication requirements. They can be customized with a wide range of features to fit your business’s unique needs. 

• More Reliable

Softswitches have in-built real-time monitoring capabilities using which they actively monitor QoS. In instances when there is a sudden increase in call load, softswitch can automatically make real-time adjustments to its configurations. This is done to ensure that communication happens without any glitches. 

VoIP Softswitch Use Cases

Softswitches are deployed extensively across various sectors and industries. Here are real-life use cases for the same:

OTT VoIP Services

OTT service providers offering VoIP applications deploy softswitches for efficient call traffic management. A popular example is Skype, one of the most pioneering platforms offering OTT VOIP services, which leverages softswitches to enable global connectivity for calls made over the internet using the Skype app. Another prominent example is WhatsApp, owned by Meta, which uses softswitches to facilitate voice calling to its users. 

Mobile and Wireless Networks

MNO i.e. Mobile Network Operators utilize softswitches to achieve a variety of goals as mentioned below:

• Softswitches ensure seamless call routing between different carrier networks. Softswitches help in optimizing the flow of calls and data across different networks by selecting the best routes. 
• Furthermore, Softswiches also contributes to roaming services by ensuring a seamless transition from the home network to other networks when a mobile phone user travels outside their home area network. 
• Another area where softswitches aid is the signaling and protocol conversion. Softswitches ensure that signals between different carriers and networks are interpreted correctly. They do so by handling the translation of signals from one format to another, called protocol conversion. 

Emergency Services

In the government and public sector, softswitches are essentially used for emergency communication systems. For critical situations that require law enforcement, fire departments, and medical assistance, softswitches facilitate emergency call routing for swift and rapid response or action. 

Telecom Service Providers

Though I have explained it already, let’s take a quick look again. Softswitches are an integral part of the working of telecom service providers. While wholesale carriers managing large call traffic leverage Class 4 softswitches, ISPs make use of Class 5 softswitches to manage their local call traffic.

What is a SIP Softswitch?

Since SIP is amongst the various protocols that come under VoIP, we can say that a SIP Softswitch is a type of VoIP Softswitch. It can be considered a bridge between VoIP and PSTN calls. It is just like an operator who is responsible for the transfer of calls to their intended destination. The SIP Softswitch works by staying informed about the call signals that pass through the software and making sure that signals reach their destination. Besides connecting voice calls, a SIP Switch also supports the transfer of multimedia messages.

How does a SIP Softswitch Work?

A SIP Softswitch works as a central point of control in a VoIP network, managing all incoming and outgoing voice and multimedia traffic. The softswitch is designed to receive, process, and route calls between endpoints, such as IP phones, softphones, and other endpoints.

• When a user initiates a call, the SIP switch checks the user’s credentials looks up the destination number, and determines the best route for the call.
• After that, a connection between both the parties i.e. the caller and the receiver is established by the switch. It also manages the session till the call is over.
• The SIP switch is also responsible for other call-related functions, such as call transfer, conferencing, and call forwarding.

Besides the above-mentioned functionalities, SIP Softswitches can also offer other services like IVR, voicemail, and billing. This makes these switches an all-in-one communications platform.

The post What is SIP Softswitch and How to Choose Best Softswitch Provider? appeared first on Revesoft Blog.

Softswitch Ownership – How to Decide?

It is always advisable to first research the market and test the functionalities of the softswitch. Besides functionality, security, reliability, scalability and usability are some parameters which you should never ignore when choosing an appropriate softswitch for your business. Also, keep in mind that lowest price shall never be the only metric for your decision. Once you are sure about the product, it is time to choose the ownership option.

Now, VoIP Softswitches can be availed in two ways –

• License Purchase
• Hosted Softswitch

A service provider depending upon their requirements and expenditure can choose any one way to get the softswitch. Let’s take a look at these two models one by one:

License Purchase

This option is suitable for those who can afford high initial capital expenditure i.e. (CapEx) and have high volume of traffic to be handled such as wholesale voice providers. To be more specific, carriers with traffic starting from 1000 concurrent calls and higher must go for the buyout option. Here you only need to pay up-front in one lump sum to buy your license and don’t invest anymore. Also, those with long term projects can gain operating expenditures (OpEx) are significantly reduced.  Some of the major advantages of opting for a license purchase are:

• Comes with higher capacity
• Easily handle peak hour traffic
• Lesser OpEx for your VoIP Business

Hosted Softswitch

Softswitches are also available on a hosted basis with a monthly rent option. This means that buyers can simply rent a softswitch and need not to worry about server installation, maintenance, and up-gradation as all this is the responsibility of the vendor. It results in very low initial investment as compared to license purchase. This option is suitable for new startups which are about to enter into the market. For VoIP providers it would be a good idea to avail the hosted ownership option in the beginning for a few months and decide to go for the buyout option if everything goes well.

Make sure you do not consider the monthly rental price as the only factor when choosing the right softswitch. Functionality and reliability are also critical to ensure uninterrupted services. Also, when you decide upon a hosted switch, make sure you check if there’s any installation fee or any other additional payments.

Some highlighting benefits of availing the hosted softswitch are:

• Reduced capital cost for your VoIP business
• Dedicated 24*7 services for switch management
• Instant setup to start retail or wholesale business

Choose the Ownership: License or Hosted Softswitch?

The post Why a Reliable VoIP Softswitch Solution Provider is Important? appeared first on Revesoft Blog.

What is a Class 4 Softswitch?

Softswitch is one of the key components for a wholesale VoIP business.  Basically, it’s a server-side software that enables you to connect one phone line to another through the Internet.  To put it more simply, it’s a software that makes IP to IP calls.  A server needs to be deployed for softswitch functionality. 

Choose the Best Softswitch Vendors

Choosing the best softswitch is necessary for optimum business performance. You should consider the following features of class 4 softswitch while selecting from the best softswitch vendors :

Billing Management

Choose a softswitch with an integrated billing system. Separated VoIP billing systems might get you in trouble like compatibility issues and lack of functionality. An integrated billing feature will give you precise control over the business. Keep in mind that unbilled call minutes bring significant loss to your VoIP business and should be prevented by any means. The billing system should also be scalable, automatic and multi-currency enabled. Check out for features like automatic invoice generation, report generation ability, call statistics or diagram. These enable you to monitor and control your service better.

Routing

How good is the routing function? To ensure cost-saving routing, it is necessary to buy routes from termination providers throughout the world. Having a wider range of routes ensures smooth business operation with maximum profit. Look for the Least-Cost Routing (LCR) function in the switch. LCR enables a softswitch to determine which outbound line will be least expensive. Percentage routing is another important feature you should look for. It allows a softswitch to transmit the call through a route that has a maximum percentage and if not available, choose the next maximum percentage. Longest Prefix Match feature matches the incoming call’s prefix with the prefix assigned to each route and selects the route with which the call has a maximum match. An automatic blockage of unprofitable calls is another feature you don’t want to miss.  

Secured Switching Function

Class 4 softswitch should be a stable and secure system ensuring efficient data (Voice and SMS) transmission.   In order to obtain better security, the switch should have VPN support and Network Topology Hiding. Using VPN means the client has to go through the VPN server (VPN is the middleman here) and encrypt/decrypt data before channeling it to the softswitch. Make sure that the VPN server and the softswitch server is the same data center.  This will avoid latency and poor voice quality. Topology hiding is a feature that assures enhanced SIP network security.  Normally, critical IP address data is sent to other networks in regular SIP traffic. Topology hiding prevents third party threats from stealing this data and attacking your SIP network.

Sales and Analysis Report

The ability to generate on demand report, Inbound/Outbound/Unauthorized call report, traffic volume tracking and revenue report help you to keep track of your business performance and accelerate business development. Having all the numbers figured out gives you the leverage to measure your business parameters and take the right business decision.  Also, look for softswitch vendors that offer Payment and Sales report, data export in XML and CSV format. 

Flexibility and Compatibility

Check out protocols and codecs compatibility before you buy your softswitch. Make sure your supplier and clients are using codecs that are supported by your softswtich. If your switch has transcoding option then protocols and codecs can be converted in the desired format. A dual-layer firewall should also be considered.  

Easy and Quick Set Up

Make sure that the softswitch set up is easy and fast. It will help you in quickly getting started with your VoIP business. Look for a user-friendly and robust management portal where all the activities can be managed which will ultimately result in better customer satisfaction, loyalty and retention. All these factors are extremely important for the success of a business. 

Post Sale Support

It is obvious that majority of the softswitch vendors will provide technical support during the whole purchasing journey, but what after that? You must have chosen the best softswitch as per your needs, but eventually you will need technical support for troubleshooting and various other tasks. Ensure that your service provider offers on-demand troubleshooting at any given time. Not only it saves you from the hassle of paying extra money for support but also lets you focus on your important business activities.

Regular Updates and Upgrades

Market Landscape is never constant. Even after you purchase the best softswitch, it is crucial to make it adaptable  in accordance with the ongoing trends. You will need to match your softswitch services with your competitors or even make it better than theirs. This means that regular updates are necessary to keep you ahead in the market.  Check which softswitch vendors provide support with updates and upgrades and if those are free or paid. You can go with the paid ones if it is worth your business requirement. 

Scalability

Lastly, avoid buying your softswitch based on only CC (concurrent calls) and CPS (calls per second) values. For example, while buying a house someone does not just look for a bigger space, right?  Apart from spacing, there are other features to look for in a house. Same goes in case of a softswitch.  CC and CPS are important but also look for features, functionality, integration and customization options.   

Getting Started

VoIP business is quite trending these days and is certainly profitable. You just need to be thoughtful and mindful. Before you choose the best from various softswitch vendors, make a checklist of the features you are looking for in your softswitch that serves your business best.  Choosing the best VoIP Softswitch will ensure maximum profit and seamless business experience for you and your clients.

 According to a comprehensive research report by Market Research Future (MRFR), the Global VoIP Market is predicted to reach USD 58.21 billion by 2025 at a CAGR of 12.2%.

What is a Softswitch?

This is one of the most common terminologies of a VoIP business which you might have come across many times. A softswitch is software used in the telecommunication network for launching, maintaining, routing, and terminating sessions in Voice over IP (VoIP) networks. Internet-based telephony and a growing number of traditional telecommunication networks use this software switch to manage the connection of phone calls.

Call switching in the telecommunication industry is a long-term practice to interface the caller to the intended recipient. It was a manual process earlier when the phone administrators shifted the phone line physically, starting with one circuit and then onto the next, to interface the call between a caller and recipient. In the present scenario, if you notice a typical VoIP architecture, the manual call routing has moved on to an automated process with the help of a softswitch.

This software consequently switches the phone lines, and it is a mix of software and switchboard. It has the programmed logic to play out this telephone line exchange. Class 4 and Class 5 Switch are the most widely used switches for routing calls through different networks. Some common types of routing are least-cost routing, loss-less routing, time-based routing, etc.

Class 5 Softswitch

Class 5 Softswitch is a strong platform with lots of interesting modern features. Through this software, a retail VoIP service provider can provide extremely rich quality IP services to enterprise and residential office customers with IP-enabled devices like landline IP phones and adaptors!

Let’s consider a scenario – If an end user wants to make a call from Singapore to Japan PSTN number, what’s the role of Class 5 Softswitch? To begin with, the call controlled by a retail VoIP solution provider will be transmitted to a wholesale VoIP provider via Class 5 Switch. What happens after it reaches the wholesale VoIP provider is explained in the Class 4 Softswitch section.

Characteristics Of Class 5 Softswitch

Class 5 Softswitch characteristics include:

• Call Authentication

It involves confirming the identity of the calling party to ensure that only authorized users can make the calls through the Softswitch. 

• Billing and Routing

While billing is all about tracking the usage of services for each user to generate bills, Routing involves determining the most optimal path for a call to reach its intended destination. 

• IVR

Interactive Voice Response or IVR refers to the technology that enables automated customer service i.e. computer can interact with humans through voice and DTMF tones input via a keypad. 

• Callback

The callback feature allows users to request a callback from the system. 

• Analog-to-Digital Conversion

In this process, analog signals or voice signals are converted into a digital format so that data can be transmitted over digital networks. 

• Support for Codec & Media Transcoding

Class 5 supports various audio codecs for compression and decompression of audio data.  The usage of different codecs has different effects on the quality of the call and bandwidth usage. When 2 communicating parties use different codecs, media transcoding ensures compatibility and seamless communication. 

• Social Media Usability

Using this feature, integration with social media platforms can be done. This enables users to call or interact with the softswitch using social media channels. 

• Call Transfer

This feature enables a user to transfer an ongoing or active call to another party such as a different department or team. 

• Call Holding

The call holding feature allows the user to temporarily put the call on hold, playing some music or greetings, while the user attends to another matter. 

• Call Forking

Using this feature, a call can be simultaneously sent to multiple destinations, for instance, when a call is to be answered by multiple parties simultaneously. 

Class 4 Softswitch

Class 4 Softswitch is mainly used for routing IP-IP calls to long-distance international locations using an IP network. Now, in our previous example where an end-user wants to initiate a call from Singapore to a Japanese PSTN number,  Class 4 Switch will route the call to a Japanese PSTN number only when a wholesale VoIP service provider receives the transfer order from a Class 5 Switch.

In addition, Class 4 Softswitch, which has fewer features than Class 5, enables cost-efficient scaling of voice services while offering a reliable presence between interexchange carriers.

Characteristics Of Class 4 Softswitch

The most important characteristics of the Class 4 solution are:

• Protocol Support and Conversion

To ensure efficient communication between different carriers, class 4 softswitches support various protocols. They also perform conversions to facilitate interoperability. 

• Transcoding

This process converts media streams from one codec to another to ensure seamless communication between carriers. 

• Calls Per Second Rate

CPS or Calls Per Second Rate is the number of calls a Softswitch can handle per second. It defines the capacity and performance of the Softswitch. 

• Average Time of One Call Routing

The average time taken by the softswitch to route a call from source to destination is called the Average Time of One Call outing. This helps in assessing the efficiency of call routing processes. 

• Number of Concurrent Calls

Another crucial capacity parameter, the number of concurrent calls refers to the maximum number of calls a softswitch can handle simultaneously. 

• Flexible UI (User Interface)

A flexible UI sets up a user-friendly environment for administrators to configure and manage the class 4 softswitch. 

• Intelligent Call Routing

This feature dynamically determines the most optimal route for each call. 

• Billing Interface Including CDR

The billing interface provides features for tracking and generating invoices. CDR refers to the detailed logs containing information about each call. 

• Secured Firewall

The firewall acts as a protective barrier that secures the Softswitch from potential security threats and unauthorized access. 

• Filtered Third-party Routing Engine

A third-party routing engine integrated with class 4 Softswitch filters and optimizes the routing of calls, thus boosting the efficiency of the call transit. 

Class 4 vs Class 5 Softswitch – Difference Between Class 4 and Class 5 Softswitch

Undoubtedly, both Class 4 & 5  Switches are robust platforms that play an important role in a VoIP infrastructure but, you need to understand some major differences between the two. Here, I have differentiated class 4 vs class 5 Softswitch based on purpose, features, business usage, capacity, and route area.

Purpose

Class 5 Softswitch is responsible for transferring calls to Class 4 Softswitch after receiving the calls. It is primarily involved in handling calls within small areas. For long-distance routing through retail VoIP service providers, Class 4 Softswitch comes into action. After receiving calls from Class 5 Switch, a wholesale VoIP service provider routes the call to the long destination with the help of a Class 4 platform.

Features Count

Class 5 Softswitch services include basic dial-tone, calling features, and additional digital and data services to subscribers using the local loop; but a Class 4 Softswitch is just a simplified solution. The main function of the Class 4 solution is the routing of large volumes of long-distance VoIP calls paralleling with other Class 4 telephone switches.

Types of Service

Class 5 Softswitch is more of a retail solution whereas, Class 4  is a wholesale solution.  This means a Class 4 switch is a central office telephone exchange that is used to interconnect local exchange carrier offices, for long-distance communications, in the public switched telephone network.

In contrast, a Class 5  Softswitch is a telephone switch or telephone exchange in the public switched telephone network, located at the local telephone company’s central office, directly serving end-users.

Business Usage

Class 5 Softswitches are intended to work with both VoIP service providers as well as end-users. This type of switch platform is for local & long-distance telephony services. So, it possesses additional service features for end-users & corporate clients such as IP PBX features, call center services, calling card platform, types of authorization, QoS, Business Groups, etc.

On the other hand, the Class 4 platform intends to serve wholesale VoIP solution providers, PSTN, Telco Operators, Carriers, etc.

Concurrent Capacity

Class 4 Softswitch can transfer a large number of calls but Class 5 Switch solution can handle a small number of calls, so it is also known as retail softswitch.

Route Area

A Class 4 softswitch routes large volumes of usually long-distance VoIP calls throughout multiple IP networks. In contrast, a Class 5 route calls to the correct IP address, SIP address, or DID number of an End user.

Benefits of Using Softswitch

Cost Effectiveness

In terms of cost, softswitches offer savings from various aspects. First, there is no need for expensive dedicated hardware thus saving money on maintenance and space. Second, due to efficient routing and VoIP use, soft switches significantly reduce the long distance and international call charges. Furthermore, when it is about scaling a business, the addition and removal of lines are easy, there is no need for additional hardware investment. 

Flexibility and Functionality

The flexibility and functionality offered by softswitches are depicted by 3 main aspects. Softswitches are not just limited to basic call routing. Rather they support a wide range of advanced features such as voicemail, conferencing, and a lot more. Moreover, softswitches perform protocol interoperability i.e. connect different types of networks and devices seamlessly regardless of the underlying protocols. Last but not least, softswitches allow customization i.e. adapt to specific needs and services. 

Network Management and Efficiency

Softswitches play a pivotal role in the management of networks through real-time traffic monitoring. These switches provide detailed insights into call patterns and network performance. Moreover, the advanced security features and fraud prevention tools offered by softswitches improve the overall security of the network. When it comes to efficiency, softswitches are easier to update and bug fixes can also be done effortlessly compared to hardware-based switches. 

How does VoIP Softswitch Work?

A softswitch functions as the brain of a VoIP network. How? Here’s the breakdown of the inner workings of a VoIP Softswitch:

• Initiation of the Call

When a number is dialed from a VoIP phone, the phone sends a SIP message to the Softswitch that establishes the call setup process.  

• Routing of the Call

The softswitch receives the SIP message and analyzes its internal routing table. Based on the present information like destination, quality of service, cost, and network conditions, Softswitch decides an optimal path for the call. 

• Call Connection is Established

When the call is within the same network, the softswitch directly connects the users on both ends. If in case, the call is to be sent to an external destination, then the softswitch may need to connect with other softswitches to reach the destination. 

• Media Processing Takes Place

During the call, the softswitch manages the packetization process. It converts voice signals into IP packets for transmission over the network. The softswitch also performs Packet Switching i.e. directs the voice packets through the network, ensuring they reach the destination in the correct order and within an acceptable timeframe.

• Termination of the Call

When one of the end users hangs up, the Softswitch sends the message to terminate the call. After that, it releases the resources that were used for the call and starts preparing for the next call. 

How do Class 4 and Class 5 Softswitch work together?

In today’s modern VoIP networks, class 4 and class 5 softswitches represent two different entities that serve different functions, but they often work in collaboration to facilitate end-to-end voice communication. 

When a user initiates a call, the class 5 Softswitch handles the local routing. If the call is to be routed to a distant location, then the class 5 Softswitch hands over the call to a class 4 Softswitch. As the class 4 softswitch takes over, it leverages its advanced routing capabilities and identifies the most cost-effective route for the call to reach its international destination.
