Thanks for your inputs, Muge. I guess ";transport=tls" indicates to Pjsip that I want to use TLS for SIP communication, while I do not want to use any security over TCP. Yes, I have already checked that Sip proxy is accepting TCP connections.....Xlite is able to register with it over TCP.

Do not forget to add ;transport=tls at the end of registrar and proxy URLs. You may use no-udp properties to disable all udp connection. There is also use-tls properties which is experimental as far as i read from the documentations. One more simple thing.. check if the proxy server accepts TCP connection (all ports and accesses configuration) Regards muge On Fri, Sep 5, 2008 at 10:58 AM, girish_kumar <girish_kumar at infosys.com<mailto:girish_kumar at infosys.com>> wrote: Hi, We are using PJSIP 0.8.0 in one of our softphone application which is working fine and uses UDP for SIP messages. Now we want to use TCP transport for SIP messages instead of UDP. For achieving the same, we replaced the input parameters in pjsua_transport_create method to PJSIP_TRANSPORT_TCP instead of PJSIP_TRANSPORT_UDP. All other method calls are same. However, now we are getting following error when PJSIP starts the account registration process. pjsua_acc.c Unable to generate suitable Contact header for registration: Unsupported transport (PJSIP_EUNSUPTRANSPORT) [status=171060] pjsua_acc.c Unable to create registration: Unsupported transport (PJSIP_EUNSUPTRANSPORT) [status=171060] Please suggest what do we need to do extra to make it work? Is it necessary to explicitly bind the transport while creating/adding the sip account. As I understand, an account would be able to send requests using any available transports according to the destination.
