Key Features in Class 4 Softswitch

VoIP is one of the industries, in which, there are various varieties of solutions available. Moreover, for the same VoIP solution, you would get various versions of offerings and each would have some same and some different features. The class 4 Softswitch is one of the most technical VoIP solutions. Moreover, it is also an expensive solution as it handles a large volume of VoIP calls and other sorts of VoIP traffic. Therefore, it is necessary to be more conscious about the selection process. It is not a solution that you can change after a year or so. Therefore, you better buy the class 4 Softswitch, which is perfect to meet your needs for upcoming years.

You may find some buyer’s guide online that can help you get the right class 4 Softswitch. I am not going to discuss the same steps of finding vendors and comparing them. Instead of that, I will share the top features, which your class 4 Softswitch must have. Knowing the fact that some features are necessary, you can make sure that you compare available options with those features. This will not only simplify your buying process, but it will also make sure that you can get the right class 4 Softswitch.

So let’s begin to explore the top features that your wholesale switch must have.

1. Call routing rules

The main job of a class 4 Softswitch solution is to route calls from source to destination. Normally, it routes calls to international destinations, and the call volume it handles is massive. The main revenue model related to this VoIP solution is dependent on the call routing method. Therefore, it is necessary to have a wholesale Softswitch that can support multiple call routing rules. This can help you add more packages and plans. 

Some of the must have call routing rules in a class 4 Softswitch are listed below:

  • Least cost routing (LCR)
  • Hybrid Routing
  • Prefix based Routing
  • CLI routing
  • Non-CLI routing
  • Lossless Routing
  • Priority based Routing
  • Cost based Routing

2. Codec transcoding

As mentioned earlier, the class 4 Softswitch traverses the calls from the source to the destination. Codec is one of the components used in the whole infrastructure setup of source and destination. The codec used at the source and destination can be different. Therefore, it is necessary to have a codec transcoding feature in your wholesale Softswitch solution. This will eliminate codec incompatibility issues.

3. VoIP billing 

The VoIP billing is not just a feature, but the whole VoIP solution. However, it is necessary to get a class 4 Softswitch solution that has a comprehensive VoIP billing solution. The wholesale VoIP business handles massive calls and each call gets charged based on different factors like call routing strategy used in routing the call, taxes, subscription model, etc. It can be a cumbersome and error prone job if the invoicing and billing are carried out manually. It would need a whole force of accountants. Therefore, it is necessary to have automated VoIP billing as part of an integrated feature or module.
