What do you mean by 'cannot'? Does it send a registration buit fails the challenge or does send no REGISTER at all before the expiry? > After some seconds > (maybe around 5 seconds ) phone reregister successfully.

Turn on debug logging, reproduce the problem and take a snapshot of your system and send it in.
