There are a couple of regressions caused by #2600 and #2859 when hanging up a call:
In the scenario of media transport creation still in progress,
pjsua_call_hangup()will try to end the session by callingcall_inv_end_session()even though it says in the log that itWill continue call %d hangup upon completion of media transport.One of the consequence of this regression is that it will cause assertion in Pjsua2 if
Account::onIncomingCall()is not implemented:Assertion failed: (tdata != ((void*)0)), function pjsip_inv_end_session, file ../src/pjsip-ua/sip_inv.c, line 2805.In pjsua2,
onIncomingCall()can be called fromonCreateMediaTransport(), i.e. when media transport creation is still in progress, so ending the session prematurely causes the above assertion.Avoid double BYE when pjsua_call_hangup() is called multiple times #2859 was created to prevent sending double BYE. Unfortunately, it will also cause the continuation of call hangup in the above scenario to fail as well since the second call hangup will just be ignored.
