[OpenSIPS-Users] b2b terminate_call!

[Jorge Henrique Pinho]

Hi Bogdan!
Here is the sip trace, opensips is on ip 10.112.137.205:5065:

[cid:image001.png at 01CE1BEC.3283E6E0]

Don't mind the duplicate '100 Trying' message. I send one in my config file before calling b2b_init_request, and b2b send the other after this.
In attachment I send the log where the opensips generates the BYE and ACK messages.

Kind regards.

Jorge Pinho

Are you sure it is not a retransmission ??

Could you post a SIP capture of the entire call ?

Hi Bogdan!
The call is terminated in both clients, the issue is that b2b is sending two BYE messages to B instead of one.
Is there any way to fix this behavior?

Kind regards,

Hi Jorge,

Why is the order important ( A or B first) ? as you simply want to terminate the whole call :).

Hi, I am using opensips with b2b module with topology hiding.
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.
Can you help me fix this?

Kind regards
