Hello i am using tls enable OPENSIPS v1.5 server. and try to register with it via symbian pjsip application (symbian_ua_gui) . the change i made with application for enable tls is 1) #define PJSIP_HAS_TLS_TRANSPORT 1 in the sip_config.h 2) make a tls setting in symbian_ua.cpp tcfg.tls_setting.cert_file=pj_str("c://Data//cert20//user-cert.pem"); tcfg.tls_setting.privkey_file=pj_str("c://Data//cert20//user-privkey.pem"); tcfg.tls_setting.ca_list_file=pj_str("c://Data//cert20//user-calist.pem"); status = pjsua_transport_create(PJSIP_TRANSPORT_TLS, &tcfg, &tid); when debuging the app is failed at SSL_Connect() method returning -1. what change i need to solve this issue.? where is the exact problem ? note i am using libraries(libcrypto.lib and libssl.lib) form openC plugins from forum.nokia for openssl. other softphone like sipek with tls which is also pjsip based is able to register using same certificates with opensips. here i attach the pjsip log file from both server and client log. Thank you. Regards, Ami patel -------------- next part -------------- A non-text attachment was scrubbed...
