Unless you have created a transaction in the course of processing the redirect, there is
no transaction to terminate, and accordingly no 487 to generate. However, these decisions
are made by the default CANCEL handling (with hooks into TM) from the stock Kamailio
config. You should not need any special logic of your own here.

Hello,
I’m using Kamailio as sip redirect server where SBC forwards the calls to Kamailio which
sends the routing back to SBC in 3xx response.
Now, I need to handle CANCEL requests sent from SBC to Kamailio. Here is the scenario:
the client sends CANCEL request to SBC which responds with 200 OK and 487 Request
Terminated and then sends CANCEL request to Kamailio.
I’m not sure how Kamailio should handle the CANCEL request here, should it send only 200
OK back to SBC or also should send 487 request terminated?
Regards,
Ali Taher
