Default 9650 Tepehones

- if the phone suddenly reboots, then there is a chance something triggers the firmware on the phone to reboot and it might be worth investigating other areas than the customer network. if customer network goes down, the phone will try the recovery algorithm for sometime (i.e., look for the gatekeeper, then alternative gatekeepers and then reboot after x amount of time) - provided that these parameters are configured properly.

- if the phone is not getting enough power over PoE (or there is power fluctuation), then this might trigger the phone to reboot

- Are there additional modules connected to it? they might drain more power.

- is the data swtich providing the necesary PoE?

- does the phone reboot while being used, or it just reboots when sitting idle?

- Do the phones all reboot at the same time? (or perhaps phones connected to a specific CLAN, or to a specific network region, or a specific data switch)?

- Are these remote phones?

- do only 9650s behave like this? or other IP phones as well?

- A reason why there is no event logs could be that event logging is disabled. Below are some details. "Log IP Registrations and events" on "change logging-levels" page 2.

- it was suggested in the previous post, choose a phone that has been behaving like this for sometime and capture a network trace from both the phone side and the gatekeeper side. that will help you to check if the problem is possibly on customer network or not.

Hope these help.
