Hi, for the SIP transport, pjsip and linphone server do support UDP, TCP But for Media transport, only UDP is supported. If you 'd like to support RTP over TCP, please see transport_udp.c in pjmedia project, and make your own transport_tcp Basically, you will not use UDP socket, but TCP socket for media packet On Thu, Apr 11, 2013 at 11:49 AM, Techie Sup <techsup0073 at gmail.com> wrote: > I too work on similar feature on routing RTP through TCP and please > share your observations if you come across with a working solution. > > Warm Regards > Selvam > > On 4/7/13, gaurav.srivastava2 at agnity.com <gaurav.srivastava2 at agnity.com> > wrote: > > > > Please check http://www.pjsip.org/sip_media_features.htm [1] > > > > On Sun, 7 > > Apr 2013 01:05:49 -0700, Haomiao Huang > > wrote: > >> Sorry, what I meant was > > that the RTP packets were still going out over UDP > >> and not TCP.
