  • April 27, 2022


Class 4 Softswitch

There has long been a discussion about which VoIP Softswitch solution is superior:

Softswitch software for wholesale, also known as class 4 Softswitch software
Software for retail softswitch, often known as class 5 softswitch

VoIP Softswitch (Class 4)

It is utilised to provide call routing services to international wholesale VoIP service providers in order to serve the wholesale VoIP business. Class 4 Softswitch software’s main function is to deliver call distribution from source to destination for large call volumes. This switch connects end-user calls to the destination, which can be local or international, for the retail VoIP service provider.

VoIP Softswitch (Class 5)

The end user receives communication services from this third-party or open-source Softswitch solution. To provide exceptional communication services, it supports all communication functions. Typically, class 5 Softswitch software is used to support local consumers’ communication needs, and it can handle hundreds of calls in concurrently.


Both of these VoIP Softswitch solutions have various features and are used for different things. As a result, each of these solutions is significant and often regarded as the top answer in its field. In the VoIP wholesale business, for example, there is no software that compares to a class 4 Softswitch open source solution. Similarly, there is no better alternative for providing great calling services to end consumers than a class 5 Softswitch open source solution.
In the grand scheme of things, both of these open source VoIP Softswitch solutions are required to complete the full cycle of communication services in the VoIP business. As a result, both of these options are the most effective for communicating.
