Hi Jorge,
trying to terminate the call on 200 ok is not really a good idea - you
have to wait for the call to establish properly (have the ACK) and do
the terminate.
Anyhow, sending a CANCEL to caller is bogus - CANCEL is all the time
sent to callee sides only.
So, I suggest to wait for the ACK to pass and only then do the terminate
stuff.

Hi, thank you for your feedback.
User A (caller) sends an Invite to User B (callee). When the Invite
arrives to opensips, b2b_init_request is called with 'topology hiding'
and the Invite is sent to User B.
Callee reply with a 200OK with sdp content, when this messages arrives
to b2b, if something is wrong with the response i need to terminate
the call in this phase, and I use the 'terminate_call' function
present in the b2b_logic module.
The b2b creates a BYE to user B (callee) but fails to generate a
Cancel to user A (caller).
It is possible to end the call at this stage?
Kind regards

Hi Jorge,
The "terminate_call" is a C function in the b2b API module. Now, I do
not fully understand what you are trying to do - could you detail a
bit the state of the involved calls when you do the terminate ?

The b2b module successfully generates a BYE to user B (callee), but
fails to generate a Cancel to user A (caller). Here is the log where
it fails to send cancel:

B2b fails to find a transaction to A (caller) and fails to generate a

Is it possible to do what I am trying or is it a bug?
