[Freeswitch-users] Why doesn't continue_on_fail continue?

[Kevin Snow]

Did you ever find any information on this? I'm chasing a similar issue.

In my case, the session is in switch_ivr_originate, an INVITE goes out.
Shortly after, mod_sofia's sofia_handle_sip_i_state() is called with state
nua_callstate_terminated with SIP error 503. It appears this is coming
from the sofia library itself as it did not receive a 503.
Switch_ivr_originate fails with NORMAL_TEMPORARY_FAILURE.

The problem is the INVITE went out but sofia doesn't send a CANCEL in this
case. We have code that attempts the call again, so another INVITE goes
out. This leaves it receiving 180 RINGING and 200 OKs for both INVITEs.
Essentially two calls but the first is dead. After a couple seconds sofia
sends a 481 Call Does Not Exist for the first Call-Id.

Of course, I have no idea how to reproduce this and it's pretty rare so I
don't have much to go on. But we do see it occasionally and I'm trying to
understand it.
