Any good SIP library for C#?

问题:

Does anyone know if there is any good library around that can be used to easily build a SIP softphone?

Thanks in advance,

Cheers, Gianluca.

Konnetic provide fully managed SIP (and MSRP if you want messaging) components for .NET development. Their .NET SIP SDK is probably the most comprehensive and is aimed at clients.

Otherwise, Microsoft's Lync server comes with a very good managed SIP library, available here: http://www.microsoft.com/en-us/lync/default.aspx Although you are tied to Lync server.

If you want a stateless solution consider http://www.independentsoft.com/

There are a number of C# libraries that are wrappers around C++ libs eg. http://sites.google.com/site/sipekphone/pjsipwrapper uses pjSIP underneath.
