Hello, I'm very new to pjsip, I discovered it only this morning, but it might be my life saviour. I'm currently involved in a project about developing an IMS client for the Next Generation Networks as defined by the 3GPP. This client will run on PDA under Windows Mobile 5/6. I'm very interested into pjsip because the WM5/6 SDK lacks a sip/sdp/rtp stack. Thus, I have a question : Is it viable to use the pjsip libs in a C# for CF.NET using marshalling ? or should i really stick with C/C++ for embedded devices for my application? The object-oriented side of C# is really appealing and the easy way to create the GUI as well. But off course it is not possible to directly use pjsip in C#, that's why i'm thinking about making an intermediate C++ code between the C# and the libs. Thanks in advance for your answers Regards, Olivier B. -- Olivier Beytrison Telecommunication Engineer Mobile: +41 (0)78 619 73 53 Mail: olivier at heliosnet.org GPG: 0x4FB83528 http://pgp.mit.edu/
