Hi, I am new to PJSIP. I want to access company PBX server with digital certificate. I was trying make changes in sample_pjsua code following the guideline given at: http://trac.pjsip.org/repos/wiki/SRTP#no1 http://trac.pjsip.org/repos/wiki/TLS I have made following changes, in BOLD: ? ??pjsua_configcfg; ? ? pjsua_logging_configlog_cfg; ?? ? ? ? pjsua_config_default(&cfg); ? ? //cfg.cb.on_incoming_call = &on_incoming_call; ? ? cfg.cb.on_call_media_state= &on_call_media_state; ? ? cfg.cb.on_call_state= &on_call_state; ?? ? ? ? //SRTP ? ? cfg.use_srtp= PJMEDIA_SRTP_MANDATORY; ? ? cfg.srtp_secure_signaling= 1; and ? ? ? ??pjsip_tls_setting tlsSettings; ? ? ? ? pjsip_tls_setting_default(&tlsSettings); ? ? ? ? tlsSettings.method = PJSIP_TLSV1_METHOD; ? ? ? ? tlsSettings.verify_server = PJ_TRUE; ?? ? ? ? ? ? ? ? pjsua_transport_configcfg; ?? ? ? ? ? ? ? ? pjsua_transport_config_default(&cfg); ? ? ? ? cfg.port = 5060; ? ? ? ? cfg.tls_setting = tlsSettings; ?? ? ? ? ? ? ? ? status = pjsua_transport_create(PJSIP_TRANSPORT_TLS, &cfg, NULL); ? ? ? ? if (status != PJ_SUCCESS) { ? ? ? ? ? ? pjsua_destroy(); ? ? ? ? ? ? exit(3); ? ? ? ? } and? changed port# to be SRTP port. ?? ? ? ? But I get following error:? 20:52:10.548 ? pjsua_core.c? Error creating transport: Unsupported transport (PJSIP_EUNSUPTRANSPORT) [status=171060] I know that I have to set certificate file in tls_settings struct but this error is killing me, I spent so much of time on this. Could you please point me what is the issue? Has any one running sample program using client side digital certificate and TLS. Thanks in advance for helping me out here!!?
