Hello,

I only work on Avaya Communication Manager, not ip office but I assume they would work in a similar way.

- is only one phone not registering or all phones?
- how does the phone get the ip address of the phone and the call server? via dhcp or manual assignment?
- did you run a trace to see what are the messages exchanged between the phone and the server? was there any error?

Thanks,
Tristan
