Hi Varun, I wouldn't recommend simply using siprtp.c as is with a few changes. But I guess that depends on what exactly you're trying to build. I used siprtp.c as a starting place for how to use the APIs in pjsip, pjmedia, pjsip_ua and others. You'll get a good idea how to use the endpoints, pjmedia_transport, pjmedia_rtp_session, pjsip_inv_session, just to name a few. I integrated these and other pjsip constructs into my application. There's a lot of good stuff in the samples directory. I'd highly recommend spending several days in there before doing any coding on your app. You'll get a much better idea of how the various APIs work and what's appropriate for you. good luck, Joel On Sat, Sep 17, 2011 at 12:48 AM, varun pratapsingh <varunps2003 at gmail.com> wrote: > Great work Joel. > > But how did you increased the number of calls.
