Also try looking in the display of a forwarded phone it should read something like

XXX - YYY

XXX= extension number
YYY= voicemail pilot

This should be able to tell you what the pilot number is so you can reforward your phone. When you forward us #603 (CF no answer) or #604 (CF busy/no answer).
If you use #601 that callforwards all calls to the destination you assigned without ringing your extension.
