<DIV><FONT face=Arial size=2><SPAN class=277095022-04072007>
We are having major problems with a remote site that links to the head office
via a VPN tunnel. The phones will register fine and work for a few minutes to
hours but then will drop their connection and will no register to asterisk even
with a restart of the phone. We have 2 other remote sites that work exactly same
and they are not having any issues so i believe it has to be be something to do
with the network rather then asterisk but this is the sip debug for a phone
trying to register. Any idea where i should start to look as this has me totally
confused as obviously the phones can communicate with asterisk at all times just
something is causing the registration to get screwed up.</SPAN></FONT></DIV>
