Try configuring CCM IP address either trough DHCP parameter, or Network configuration on the phone.

I cant test my 7941g because i keep getting a small bullseye on the bottom left corner of the screen


Your phone is trying to connect to a TFTP server address to download a firmware and/or config file update. You need to figure out what IP address it is trying to connect to (You may have to use wireshark or another packet sniffer to determine this).

Once you know the IP it is trying to connect to, you'll need to set up a small network with a TFTP server running on that same address, and feed the phone a firmware update and/or config file. It will likely not fully boot unless it gets a firmware update.

Phone looks fine but there are lines through the connection. I dial and get busy signal. Check all connections, everything seems fine, reset the phone a bunch of times, still not connected though.


If there are lines through your line appearances than your phone is likely not properly registered with your Callmanager or SIP registrar, you need to configure your phone properly so it registers and associates with an extension on your PBX or hosted service.

How power need Cisco 7941G-GE IP Phone


These phones can take their power from a Power over Ethernet switch, where all you need to do is plug the phone in to the switch and it gets its power from there.

You can also get power cubes for these phones, but they do not come with the phone as standard, as most people like the convenience of having the power coming from the switch, and not needing to use up a further power socket in the floor/wall.

Hope that this helps!

Good day! How Cisco 7911G IP Phone can connect to the Call manager Cisco 7912G IP Phone?


You must have a valid functional callmanager. You then set option 150 in your DHCP which specifies the IP address of the TFTP server which is ultimately callmanager.

How do you hide the displayed number on Cisco Phone?


You will need to modify the template assigned to that particular phone. Depending on the service you are using (CallManager onsite or hosted VoIP, or other options), you may or may not actually have access to make these changes.

Is the phones registered to CallManager or CME?
if CM, then it could be because of partitions and Calling Search Spaces. PTs are placed on the line and are restricted by CSSes. http://cisco.com/en/US/docs/voice_ip_comm/cucm/admin/4_1_3/ccmsys/a03ptcss.html#wp1020642

If it is CME, then it could be a configuration issue
