7940s don't reregister with CM after WAN outage

Unanswered Question
Dec 9th, 2008

Can anyone offer any help for the following? We have several remote sites with Voip phones (7940 series) that are connected to a central Call Manager. At a couple of those sites, whenever there is a WAN outage, the phones aren't automatically re-registering with CM once the WAN link is reestablished. In one case, the VOIP outage was overnight.

Other sites come back with no problems.

Any ideas what to look for?


I have this problem too.
