[OpenSIPS-Users] B2b 'terminate_call' function!

[Jorge Henrique Pinho]

Hi, I am using b2b module with topology hiding.
I am trying to terminate a call when i receive the 200OK response to an Invite. To accomplish this i am using the 'terminate_call' function defined in b2b_logic module.
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:

Feb 28 15:01:41 [1466] DBG:b2b_logic:b2bl_parse_key: hash_index = [286]  - local_index= [0]
Feb 28 15:01:41 [1466] DBG:b2b_entities:b2b_parse_key: hash_index = [310]  - local_index= [66]

Feb 28 15:01:41 [1466] ERROR:b2b_entities:b2b_send_request: No transaction saved. Cannot send CANCEL

B2b fails to find a transaction to A (caller) and fails to generate a Cancel message to this user.

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

Kind regards

Jorge Pinho
