Hi Bogdan! I trigger terminate_call function when b2b receives a bad formatted 200OK to an Invite request. In this scenario I need to immediately terminate the call.

Where do you trigger the terminate_call function ? in what context and from where exactly ?

It is supposed to send the Bye, but b2b is generating two BYEs (it is not retransmission) to end the same leg. You can see in the attachment the pcap capture that show this behavior. Do you know why b2b is generating the extra messages? Kind regards!

Why it is not supposed to send BYE to B ? if you do terminate_call, all legs will be terminated.

Yes, I prefer to use b2b, if you can look into the problem I'll be very grateful. Kind regards!

If you are keen to use the b2b, I can look into the problem.

It choose b2b support with topo hiding because this way the module will automatically match and forward requests and replies. In this example when I receive a bad formatted 200OK I need to immediately end the call. The call is ended in both clients but b2b is sending two BYE messages to B instead of one. What could be causing this behavior?

For these you can simply use the dialog module, which is a much lighter approach (with less probability for complications). Have you consider to use the dialog module, with topology_hiding() script function and dlg_end_dlg MI function ?

I am trying to terminate a call when i receive the 200OK response to a Re-Invite. To accomplish this i am using the 'terminate_call' function defined in b2b_logic module. The dialog is establish and an user sends an in dialog Invite to renegotiate codecs, but the 200OK reply is mal formed. In consequence I need to terminate the call at this stage. To accomplish this I am using the terminate_call function present in b2b_logic module. When I receive the 200OK bad formatted message, I invoke the terminate_call function. The behavior of b2b is this : A ----------------- Opensips (B2B) ------------------------ B A Re-Invite --> | Re-Invite --> B A | 200 OK* <-- B *Bad formatted 200OK A BYE <-- | B A | BYE --> B A | ACK --> B A | BYE --> B It seems that b2b is sending a first BYE to B that was not supposed to. Log is in the attachment. Can you help me fix this?
