4621SW IP Phone loses connection but doesn't restart

[gddoec]

Have a customer with an IP500v2 8.0.16 and a remote 4621SW IP phone. Phone works. But every 5-10 mins or so, it seems to 'roll' from page 1 to page 2. Phone never reads discover (call server address). If you are on a call, it will lose audio and buttons don't work (park locations, other appearances. All seem to be frozen). It will still show call connected and time continues. Eventually it will disconnect on its own. Then everything works fine again-dial tone, ability to receive calls, etc.

Tried phone both at my office (Linksys 8-port router) and at customer site (sonicwall) with same results

Any thoughts?

The remote (system side) router will be effecting traffic/ports, seen similar before
