[OpenSIPS-Users] B2BUA marketting scenario

[Bogdan-Andrei Iancu]

Hi Sebastian,

The 200OK from FS must be followed by ACK+SDP to linphone. See:
     http://www.opensips.org/Documentation/Tutorials-B2BUA#toc14

If this does not happen -> do you see any errors in the logs (around the 
processing of 200OK from FS) ?
