Cisco CP8831 installation and Registraion for making a call (Urgent)

[Ibrahim Bhuiyan]

Hi,

I have purchased a CP8831 phone. After installing with my network it shown "Not Registered". So how can I register this phone? What does need for that? Need any License or any Firmware, etc. So that I can make a call. Please explain in detail.

Hi Ibrahim,

I'd recommend to start with reading and watching video on:

https://supportforums.cisco.com/document/86036/ip-phone-sccp-sip-phone-registration-process-cucm

this should help you understand how phone registers and needs to be configured.

HTH,

First thing, have you even added the device to Call Manager?

Logged into CUCM Administration - gone to Device - Phone and add new?
