IctBaden.pjsua2

.NET wrapper for PJSUA2 (not the first one).

There are several others on nuget:

• pjsip-pjsua2-csharp, PJSIP 2.8
• pjsip-pjsua2-cs, PJSIP 2.10
• more on nuget.org...

For more information about the PJSIP project see https://www.pjsip.org/

Motivation

The problem was, only pjsip-pjsua2-cs uses PJSIP version 2.10.1, that is also not the latest. There is no public repository to build that and mailing the owner has not answered.

pjsip-pjsua2-csharp is two years inactive.

So i decided to do it my own, using the help of pjsip-pjsua2-csharp's build-it-yourself documentation (thanks a lot).

What is in the Package

pjsua2.net.dll - .NET Core (netcoreapp3.1) wrapper library
pjsua2.dll - Native Windows x64 PJSUA2 library including SWIG generated C# wrappers

Extensions

The pjsua2.net.dll includes two additional static classes:

    public static class PjsipInfo
    {
        // Get included PJSIP version
        public static string GetVersionInfo();
    }

    public static class PjsipExt
    {
        // Enable the pj-media-neg extension
        public static int EnableTelephoneEventNegotiationExtension();
    }
