NOTICE: This framework is being deprecated and is no longer under active development. We've since adopted the Azure DotNetty, another reactive socket-server implementation for .NET. for the underlying socket implementation. Please use this library ModFreeSwitch going forward.
This framework helps interact with the FreeSwitch via its mod_event_socket. For more information about the mod_event_socket refer to FreeSwitch web site. It is fully asynchronous. Also it offers more flexibility for extension by any other developer who picks the source code.
In its current state it can help build IVR applications more quickly.
The framework in its current state can be used to interact with FreeSwitch easily in:
- Inbound mode Event_Socket_Inbound
- Outbound mode Event_Socket_Outbound
- One good thing it has is that you can implement your own FreeSwitch message encoder and decoder if you do not want to use the built-in ones
Looking at the asynchronous nature of the framework it will be better using it in a event-driven or message-driven architecture.
Do not block any method by using Wait() in production. It may hinder performance
