[OpenSIPS-Users] ACC problems

[Brett Nemeroff]

Hello List,
I'm having a problem with the ACC module in 1.5.3. For most call flows,
there isn't an issue capturing the necessary elements. But for this one
flow, that I seem to be getting over and over, there is a problem.

The call is canceled at the same time a 200 OK comes from the destination.
The CANCEL is retransmitted a few times and then is replied with a 200 OK
(canceled after 200 OK for invite). Seems like a race condition of sorts.
Then about 7 seconds later, the originator sends a BYE *also*. Opensips
ignores the BYEs and the originator retransmits it a few times. Then gives
up.

Then the dialog module kicks in with the dialog timeout (4 hours later).

The resulting ACC records are unusual and I'm really not sure what to do
with them. They basically look like:

INVITE->183
INVITE->200
CANCEL->200
BYE->200 (generated locally 4 hours later).

Seems like something is horribly wrong here.. no? Any ideas?


Thanks,
Brett
