even if it is a bug, the ATA should try to register again at regular interval (reg. interval, specified in the ATA config.)
We've been asking Grandstream the same question for the last few weeks. They seem to be very hit and miss with re-registering on their own if there is any kind of service interruption (even a few seconds).

They are "aware of the issue" and "hope to fix it in the next firmware".

We're still pressing for a better answer than that.
