Yep, it's what I tried.<br><br>Actually, it's in a lab version, so I do several tests with 2 small servers.<br><br>The big picture is :<br><br>UA -> stateless proxies (with dispatcher) -> statefull+registrar proxy<br>
<br>Later, the dispatcher will be used to send Register requests to 2 different registrar servers, and Invite requests to 2 different statefull proxies.<br><br>In this actual case, the dispatcher list file contains these lines :<br>

Ok, that's the info I was looking for :)..<br>
<br>
Looking at that group, should I understand you have only one
destination in there, while having the "use_default" on ? This
makes a bit of none sense - the group has only the default
destination (to be used in case of failure), but no regular
destination ??<br>
<br>
Anyhow, there is a bug there, but I want to understand your setting,
to be sure that the fix will be the right one ;)<br>
<br>
