Hi, I have configured "enable-3pcc=proxy" in the SIP profile, and have an external application that controls answer-call, make-call, etc. The configuration means that incoming calls w/o SDP are accepted, which works fine. The problem is that when I make an outgoing call, ringtone is not played to the caller, although the "ringback" variable is set for the caller's leg. I have checked the code in mod_sofia, and in sofia.c, there is a piece of code: if (sofia_test_flag(tech_pvt, TFLAG_SKIP_EARLY)) { sofia_clear_flag_locked(tech_pvt, TFLAG_SKIP_EARLY); goto done; } which disables reaching the ring-ready state. TFLAG_SKIP_EARLY is set when TFLAG_3PCC is true. If I comment out the goto statement, the A-party gets ringtone. N.B.: This is just a minimal quick fix, not a proposed solution, which works because I'm not doing an enterprise originate. Question: Is there a reason for this behavior? Documentation shows that early media must be disabled when an enterprise originate is done, but why is playing ringtone disabled in this case? Should I submit a bug report to Jira? Best regards, Jaan
