Question about Cisco 7905 IP Phone
Posted by Anonymous on
the reason for this would be that it is not getting it's config from the CallManager (or CME router).
The steps in a phone booting up something like this:
1) DHCP for IP Address, and Option 150 for TFTP Server
2) TFTP to address provided by DHCP Option 150
3) Get config file, a(an upgrade of firmware may occur at this point)
4) Connect to Call Manager/CME as specified in config file
First check DHCP server to see if it is allocating an address to the MAC address of the phone
Second confirm if DHCP is providing Option 150 and that is the IP Address of the TFTP Server (typically one of your Call Managers)
Third check that the phone is correctly configured on CCM/CME. A common error at this stage is that the phone is configured with the wrong model type.
Call back if you get to that stage and are still having problems.
