Hi Tasfin, You can develop a switch using PJSIP but don?t use PJSUA. Instead, use the ?low? level libraries like pjlib : receive and process INVITE, retrieve SDP and send it to your audio switch? ./pjsip-apps/src/samples/simpleua.c is a good point to begin when you remove all pjmedia references. Thanks Poq De : pjsip [mailto:pjsip-bounces at lists.pjsip.org] De la part de Tasfin Hasan Tareque Envoy? : jeudi 13 f?vrier 2014 08:09 ? : pjsip list Objet : [pjsip] How can I forward SDP without changing? Hi Everybody, I want to develop a proxy switch using PJSIP. I have run PJSUA and call to PJSUA by using another dialer but PJSUA response me by 406. I think, this is codec problem thats why PJSUA sending 406 response. In the PJSIP, there is any way that PJSIP will work as proxy switch without handling audio part(SDP). Audio (SDP) will handle another switch. This proxy switch(PJSIP) will only forward the SDP to other switch without parsing or modifying. ?Thanks? -- Tasfin -------------- next part -------------- An HTML attachment was scrubbed...
