Hello,

why do you need to process cancel requests? They have special routing requirements related to associated invite and sent from tm directly. The event route is for the requests sent by modules via tm.

Haven't tried, but maybe onsend_route will capture it.

Cheers,
Daniel

Hi All,

in a call forking, after one branch answer the call (200 OK reply), a CANCEL SIP message has been sending to other/another branch(es) and I need to process this/these cancellations in configuration file. After reading some documentations, I discovered there is event_route[tm:local-request] block, which is executed when tm generates internally and sends a SIP request, Such cases are:

SIP messages sent by msilo module

SIP messages sent by presence server

SIP messages sent by dialog module

SIP messages sent via MI or CTL interfaces

I didn't understand very well this cases, so I insert event_route block in my kamailio.cfg but neither CANCEL SIP message or other requests generated by tm module was handled by event_route. I must be using wrong concept to handle this CANCEL SIP message, it's possible handle this messages in configuration file?

Best Regards
