<p>Hello,</p>
<p>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.</p>
<p>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.</p>
<p>Cheers,<br>
Daniel<br>

<tt>Hi Yuriy,<br>
<br>
thanks for the suggestion.<br>
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.<br>
On the contrary, I can see that OPTIONS, NOTIFY and also PUBLISH
messages are there.<br>
<br>
Do you have any other suggestion?<br>
<br>
Thanks<br>
Regards<br>
Marco<br>

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