7940s don't reregister with CM after WAN outage

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?
