According to the RFC, the UA calculates when to initiate a reREGISTER based on the expiry time. It's a percentage of the expiry time, minimum x seconds (don't remember right now). If there is a time problem on the UA, this calculation can fail, so I would start looking there. Also, I have seen some UAs (older Grandstreams) coming in with a reRegistration too late (after the contact being expired). If the UA doesn't understand that, it can end up without registration.

Let's bring it up: who are the vendors, the models, the firmware versions ... ;-) g-)

I am seeing the same thing at a few of our sites so if anyone has any insight, I would be interested as well.
