Hi All I had gone througth the FAQ section of pjsip at http://trac.pjsip.org/repos/wiki/FAQ#adding-codec Problem is our web server supporting the ilbc codec only ... So i hve to enable or add the ilbc codec.. At Faq section they have told simply the replace gsm.c file with adding new codec functionalities.. My doubt is pjmedia-codec containing the 5 files gsm.c, ilbc.c ,speex.c,g722.c etc... It is confusing me, where i have to the chnges to enable the ilbc codec Thanks Yuvaraj R -------------- next part -------------- An HTML attachment was scrubbed...
