Firmware upgrade for 7942G IP phones Phone

1. We are running Cisco CallManager 4.3. We have recently acquired Cisco 7942-G IP Phones running sccp 42.8-3-3sr2s load file.

2. When we connect the new phones to the network, they are able to go through the IP Phone configuration process on the network i.e, acquire power from the POE switches, acquire VLAN settings from the switches, acquire IP address configurations from the DHCP servers (Routers in our case) including the IP address of the CallManager (which in our case is also the TFTP server).

3. After the 7942-G IP Phones complete the IP address configuration process, they are attempting to register with the CallManager. However this is not possible since the CallManager in its present state does not have the necessary files and configurations to support the 7942-G IP Phones.

4. we installed  the file cmterm-7942_7962-sccp.8-3-3sr2.exe

firmware and the zipped files in after download cmterm-7942_7962-sccp.8-3-3SR2.zip,

the installation process was successful,

4. However even after installing the firmware the Callmanager New IP Phone addition procedure drop down menu does not provide the 7942-G IP Phone type

Can anyone assist with where i can get the file cmterm-7942_7962-sccp.8-3-3-readme.htm which i believe could have more information.

Anyone with an idea of what we can do.

thanks

Re: Firmware upgrade for 7942G IP phones Phone

Hi,

Can you check if you see just 7942 or 7962 as valid phones from the add phone drop down list

If they are there - that is what you use.

If they are not there in the list you need to load and install the latest device pack 22

Please see this link

Firmware upgrade for 7942G IP phones Phone

Hi,

Can you check your call manager version number

For 7942G/7962G support you need to be using at least 4.3.1
