<tt>Hi, Milan!<br>
<br>
The only SIP method that can refresh a SIP dialog is a re-INIVTE
(according to RFC 3621 [1]) or an UPDATE (according to RFC 3311
[2]). A REGISTER message cannot change the Contact of an ongoing
dialog. Therefore, your application has to send a re-INVITE after
it connects to a new network.<br>
However, there is a small limitation in the dialog module that
doesn't allow you to update the remote-address (Contact), not even
for re-INVITEs or UPDATEs. But there are some guys that are
working to fix it, luckily the fix will be out soon.<br>

<div><br>

</div>
<div>I'm running into next issue:</div>
<div><br>
</div>
<div>My SIP clients register to Opensips server with Expires
interval of 3600 seconds and calling/initializing call to
other SIP client or PSTN network works fine but issue comes
when my SIP client send re-register during active call (it
sends re-register 300 seconds after initial REGISTER message
or in case IP/network on which it is has changed since those
are mobile SIP clients) . So when calling SIP client
re-register Contact field for that AOR will be updated to new
value ( It will change network socket , IP:Port ) and if/when
called party (either PSTN or other SIP client on my
network) wants to hangup that call BYE that comes from called
party is not send to new/updated Contact of caller , rather it
is trying to send it to "old" Contact which does not exist any
more.</div>
<div><br>
</div>
<div><br>
</div>
<div>Do you have any idea how I could fix this so that BYE goes
to new/update Contact value ?</div>
