This is a weird one for me. We're using a hosted PBX flavour (Bicom systems) and something has changed on the LAN that is causing various extensions to not be registered all the time. The only thing that appars to have changed is the removal of Exchange from the LAN to a data center. There is a VPN tunnel up, but only the traffic destined for Exchange is fired down the tunnel, everything else goes out the ISP's gateway. At night when there's no traffic the extensions all seem to register, but in day 2-5 extensions will be unreachable for inbound. Of course they call outbound because the extension will authenticate fine.
The phones are all Aastra, mostly 6753 I believe, but all about a year and a half old. The firewall is a SonicWall and was installed previosly without problems until the Exchange got moved off site. Any insight is greatly appreciated.
