Dear ALL:
I try to make a call from UA1 to UA2, and UA2 is busy. So the call
will forward to another UA3.
UA1 ==> UA2(busy) ==> UA3
But when I watch the log, I find that miss the following log (diff
with call from UA1 to UA2 and directly forward to UA3)
UA1 ==> UA2(callfwd) ==> UA3
Feb 22 12:15:07 ser mediaproxy[18476]: session
16AA8C75-5EAC-403C-85DA-C5D9BDFD15C7(a)10.18.1.70: started. listening on
xxx.xxx.190.248:35026
When I make a callfwd call, the call will run route[2] but not failure_route[1].
UA1==>UA2(callfwd)==>route[2]==>UA3
And I make a fwdbusy call, the call will run route[2] then pass
failure_route[1],
and return to route[2].
UA1==>UA2(fwdbusy)==>failure_route[1]==>route[2] =XXX=> UA3 ????
Why does the method be failed? Do I must "end_media_session()" before
start a busy call?
How can I modify it?
