Hello,
the last option to try is onsend_route and if the CANCEL shows up there,
then use some string operations over $snd(buf) to get the Via branch,
last value after "." being the branch index. I am not sure you can get
the INVITE avps there, but you can try.
Otherwise a new event route has to be added for this purpose. Probably
not much coding, depends of what is wanted to be exposed there, as the
cancel is generated locally, there is no incoming sip_msg_t structure.
Cheers,
Daniel

Hi Yuriy,
thanks for the suggestion.
I tried both "event_route[tm:local-request]" and
"event_route[tm:local-response]" but internally generated CANCEL
messages are not captured by those event routes.
On the contrary, I can see that OPTIONS, NOTIFY and also PUBLISH
messages are there.
Do you have any other suggestion?
Thanks
Regards
Marco

You can try event_route[tm:local-request] for
this.

Hi All,
I have a question regarding call forking and how to access failed
branches: the ones for which kamailio sends out the CANCEL
because on
another one a 200OK was received.
This is the scenario:
- A calls B
- 3 devices are registered on B, so a parallel forking is done
to B1,
B2 and B3
- B1, B2, and B3 all reply with 180 Ringing
- B1 replies with 200OK
- Kamailio CANCELs the branches with B2 and B3
What I need is access to each single CANCEL that Kamailio sends
out to
B2 and B3.
In particular I need to know the branch-id and Via branch of all the
cancelled branches. Additionally it would be perfect to have them
inside
the TM module, in order to have access also to internal AVPs.
I tried with dedicated failure routes and also with per-branch
failure
routes, but I was never able to access to those values.
I also didn't found a specific event-route that can help me solve
this
problem.
Does anyone have an idea?
Kamailio version 5.2.5
Thanks
Regards
Marco
