I have 1 x T54W phone just setup , we notice an issue where the phone doesn't ring for incoming calls .
You can pickup and make a call out
If you reboot via power cycling the phone it will ring , then randomly it wont receive a incoming call until you power cycle it ???

Sounds to me like it's losing the registration/connection to the server.

I think the SIP service provider should be able to assist you with something like this. Perhaps you're not re-registering in a timely manner or you don't use properly Keep Alive.
