Is this what is happening?

1. Phone rings but does not answer
2. Phone reregisters as normal (after an hour?)
3. Phone rings but does not answer
4. Phone fails to register

If so, then it is a known problem. Grandstream know about it and should
have put the fix into 1.0.6.7 but they mucked up. It should be fixed in
the next release. This only seems to happen with the BT10x phones.

What I have done to alleviate it is to set the "Register Expiration" on
the phone to some large value. It's not perfect, but it helps.
