On a remote VOIP site, I'm getting 'service unavailable' on all the phones (Nortel 1120e) when trying to connect to the PBX. The phones have static DHCP including the signalling server
Can someone shed some light on this error, is it a switch error or a phone error?
What sort of troubleshooting steps are there for this. My phone provider isn't being much help.
Thanks
Steve
