Hello All, ? ? I am trying to configure my iOS app (which uses pjsip as you can guess :) to use TLS. It works perfectly fine with UDP. I have built the libraries as advised, and I have checked that TLS is well enabled during the build.. Have a look at the output of the configure script.. checking for OpenSSL installations.. checking openssl/ssl.h usability... yes checking openssl/ssl.h presence... yes checking for openssl/ssl.h... yes checking for ERR_load_BIO_strings in -lcrypto... yes checking for SSL_library_init in -lssl... yes OpenSSL library found, SSL support enabled Now to enable TLS, I am using the following code: pjsip_tls_setting_default(&app_config->tls_cfg.tls_setting); app_config->tls_cfg.port= 5061; status = pjsua_transport_create(PJSIP_TRANSPORT_TLS,&app_config->tls_cfg, &transport_id); But I always land up getting the following errors, here is an extract from the logs :? 22:44:44.875 ? pjsua_core.c? Error creating transport: Unsupported transport (PJSIP_EUNSUPTRANSPORT) [status=171060] 22:44:44.876 ? ? ? ? call.m? Error setting G722/ codec priority (Err. 5) 22:44:44.876 ? ? ? ? call.m? Error setting G7221 codec priority (Err. 5) 22:44:44.876 ? ? ? ? call.m? Error setting G729 codec priority (Err. 4) Request you to please share any information that would help me to resolve these errors. I am using the latest version from the SVN and?ios-openssl-master for OpenSSL.
