Hi Jignesh,<br>
<br>
I don't think that it should matter if you send reInvite or Invite to
UE-B.<br>
I will explain what happens if you use the refer scenario:
<a class="moz-txt-link-freetext" href="http://www.opensips.org/Resources/B2buaTutorial#toc15">http://www.opensips.org/Resources/B2buaTutorial#toc15</a>. This scenario
tells the B2BUA to pas through on the other side all requests until it
receives a Refer message - when this happens, the B2BUA will end the
dialog with the endpoint that sent the Refer and connect the other
party with the URI in Refer-To header.<br>
This has nothing to do with the other dialog where A and C are
connected. That dialog might neither exits - there is no connection
between the two and you can not put a condition of this kind (
referring to another dialog) in the B2BUA scenario.<br>
<br>
Regards,<br>
Anca<br>

Hi Jignesh,<br>
<br>
This scenario will work with the B2BUA component if you use the refer <br>
scenario, but you have to put the B2BUA in the middle of the call from <br>
the beginning (the call where the REFER is received, in your example <br>
from UE-C to UE-B), it is not possible othervise for it to send a <br>
reInvite in that dialog if it is not controlling it. The only thing
that <br>
you won't see is the Notify at the end sent to UC-E, now B2BUA does not <br>
send this.<br>
<br>
Regards,<br>
<br>
