Hello, I just found a good SDK and I was able to create an own application with it in C#. I found it great because it is flexible and compatible with numerous PBXs. By the way the SDK is called Ozeki SIP SDK, the development time was greatly reduced with the help of this tool. If you are interested here is the sample I used: http://www.voip-sip-sdk.com/p_89-sdp-sip-calls-voip.html (Working with SDP in VoIP SIP calls) I hope this tool will help for others just as it helped me previously. Regards
I am also searching out this tool for developing my project website on the base of C# language. Thanks for sharing this tool here with proper link. This is beneficial to me for my work.
