IP Phones not connecting

[ECartman]

Hi Guys,

Have an issue with a 450 R6 (fully patched) where it rebooted for no reason. It came up with default IP (192.168.2.1) but everything else was normal/unchanged.

I reverted by to original IP, now IP phones will not connect. BCM monitor/usage indicators shows blank where IP sets should be detailed.

Tried restarting UTPS and IPtelprovider. Also rebooted a few times and no joy.

Anyone got any thoughts ?

Thanks in advance

Turn out it was a subnet mask error. This is one screwed up network :-(
