[OpenSIPS-Users] B2BUA not responding to reinvites

[Bogdan-Andrei Iancu]

Hello Kevin,

Once the B2B session started, the sequential request will not land to 
your script as they will be captured by B2B before the script (and 
handled according to the XML script).

Still, with debug level 6 you should see various messages from OpenSIPS 
when the B2B would handle the re-INVITE.

Are you sure the re-INVITE is actually reaching OpenSIPS on the right IP 
and port ?

Regards,
