All IP Phones keep rebooting

[telephonesteve]

The system is a BCM 400 4.0.2.03.
All phones are i2002.
On Friday my customers phones keep going offline and rebooting.
The screen says "Server unreachable restartinig in xx seconds". Once it does connect it only stays connected for 30 seconds +/- then reboots again.
When it does connect the phone works fine (for 30 seconds that is)
System has been in 4 years with no problems until Friday.
All digital phones and all other functions are working correctly.
Any thoughts.
Thanks Steve

Network issues I'm sure, are the IP phones off site?

Yes. But I'm at the main office where the BCM unit is with a i2002 and I get the same thing.
I'm coming directly out of the BCM to a POE switch and the phone plugged in there.
I have my laptop plugged in to the port on the phone and I can ping the server address that is says it can't reach. I tried using DHCP but the result is the same, but the BCM is handing out DHCP address to the phone and laptop.
Thanks

Find who changed your network configuration on Friday and what they did.

I'm always suspicious of other people's work but all IPs, etc.are as they should be. I still have my original job notes from 4 years ago and everyting is the same. The phones are running on a completly physically seperated isolated network so any config changes to the data network should not impact the phones.
I have a PoE switch plugged in to the BCM LAN port and just one i2002 phone plugged into the switch and I still have problems.
The phone registers, works for 30 seconds, then go to "server unreachable" once you either press now or once the countdown timer expires in connects and the whole cycle continues.
The phone does works for the 30 seconds once it is conncected.

UPDATE:
I went in early this morning before the office was full, did a back-up and then a nice warm reset and everything is good. Crazy computers.

The last time I saw this problem someone had assigned the BCM IP address to another server. Changed that server's address and all was good.

 

[telephonesteve]

Interesting. I'll contact the IT vendor and see if he assigned that IP to something else recently. Maybe he didn't document that he gave me that IP address. Thanks for the idea.

I also saw an issue like this after someone has played with the QoS settings on some parts but not the whole network....
