Same problem here with the 3800 series if I allow more than 600 minutes to lapse (10 hours) without firing up the phones.

Try this. Power-cycle the router, wait for it to settle then power up the phone(s). Seems to work for me. A Cisco guy said it has something to do with the establishment of the secure vpn tunnel and timing out after a period of non-use. Once the phone(s) are up they stay up.
