    Hi,

    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.


    Cheers, Simmo99.

Hi,i wanna use cisco ip phone 7940 as sip ip phone.when i power up the phone ,it can get ip from network,but finally,it shows "TFTP timeout"in display led.All the buttons can not be used.What...


Hi,

the DHCP server should be providing the address of the TFTP Server as DHCP Option 150. The most likely problems are:

Option 150 not defined, or not the correct IP address of the TFTP Server.
Or possibly your TFTP Server is not functioning properly.

If you have not Option 150 defined, the phone will use the default gateway as the TFTP server address.

Cheers, Simmo99.

Cisco IP Phone 7940 and 3com nbx as 3rd party SIP phones


Here are the instructions for configuring these units for 3cx

Since the 3cx softphone worked well, I don't see why you couldn't configure each as for 3cx and make them work as well.

This phone can be access through a menu/ setting buttons.

Useful link on how to navigate through the phone:

I think the main problem is to determine the intergrated router or Call manager configuration
You can also connect on switch and type:show cpd neighbor This will show the physical port connections

Phone stuck in Configuring IP


Did you check the TFTP settings on the IP phone? You may need to disable DHCP on the phone and assign the TFTP manualy or make sure the correct TFTP server is assigned.
