Daniel,
The pcap shows only one leg of the the communication (I guess caller
versus OpenSIPS). So I cannot see what happens on the callee side.
Still, I see the first cancel is rejected with 400 (I guess by OpenSIPS
- check the logs to see the reason) and the second one is accepted by
OpenSIPS (no idea if relayed to callee or not). Still, if there is a
race between the cancel from caller and the answer from callee, it is up
to the caller to sort it out....according to RFC, the caller must ACK
the received 200 OK (even if CANCEL was sent) and if it really wants to
terminate the call, it has to fire a BYE.

Hi Daniel,
Without a pcap showing the signaling is hard to understand (not to
mention helping) your scenario. Please provide a link to the pcap
or ngrep.

Hey
I had a problem when receiving simultaneous CANCEL from customer
and 200 OK from gateway.
Seems that the first CANCEL was rejected, but the second CANCEL
was accepted. This second CANCEL did NOT go to the gateway, just
Opensips received and replied with 200 OK.
This is the log of the first CANCEL:
Feb 15 18:39:22 /sbin/opensips[28845]: SCRIPT:TRAFFIC:WARNING:
method CANCEL ([email protected]/
<http://[email protected]/>XAeG2xj278512T2
/ 1839212581509953 ) not validated and not fixed ( code=-1 )
code -1 is the return of validate_dialog()
Second CANCEL didn't generated a log.
Shouldn't all CANCELs be rejected? On this case, just the first
one was rejected.
I'm using version 1.9.11.
