<tt>Hi Sebastian,<br>
<br>
The 200OK from FS must be followed by ACK+SDP to linphone. See:<br>
<a class="moz-txt-link-freetext" href="http://www.opensips.org/Documentation/Tutorials-B2BUA#toc14">http://www.opensips.org/Documentation/Tutorials-B2BUA#toc14</a><br>
<br>
If this does not happen -> do you see any errors in the logs
(around the processing of 200OK from FS) ?<br>
<br>
Regards,<br>
