<tt>Hi Jorge,<br>
<br>
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.<br>
<br>
Anyhow, sending a CANCEL to caller is bogus - CANCEL is all the
time sent to callee sides only.<br>
<br>
So, I suggest to wait for the ACK to pass and only then do the
terminate stuff.<br>
<br>
Regards,<br>
<br>
</tt>

<tt>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 ?</tt><br>
