I have an ASUS N66U with several VoIP phones behind it. I am running 1.28.0000 MIPSR2-132 K26 USB BT-VPN. When the phones first boot up they work fine but periodically throughout the day they drop their registration and then register again when the re-register timer (currently set at 180 seconds) expires. I am running SIP over TCP. This experience is duplicating over 2 separate locations, both with the same ASUS/firmware combo but with different phones (one site has Polycom 550 and the other has Cisco SPA514G). I have turned off SIP ALG as well. Does anyone have any hints or suggestions?
