I had just got a new Cisco 7942 installed in my desk. For first time when the phone booted up it showed some four digit no. on the top right line. for eg it was 2466 in my case. After some time I was going thro some menu and some message displyed "Erasing XXX". After that phone restarted and that four digit no was not displayed then afterwards. Can you tell me how to configure that no. because probably that might be the epabx no.
