Upgrading Cisco 7841 without CUCM

[Darius Byrd]

Hey everyone, we have a Cisco phone (7841) that is stuck in registration mode and trying to upgrade the firmware. We disabled CUCM in our environment and i'm trying to figure out other ways to upgrade the firmware for Webex Calling.

We successfully migrated all of our phones to Webex Hub.

Following the link Keclair provided - https://help.webex.com/en-us/article/n19c71/Migrate-Your-Phone-to-Webex-Calling

Step 1

Select Admin Settings > Network/Ethernet Setup > IPv4 Setup.

Step 2

Scroll down to the Alternate TFTP tab. By default, this is set to No. Edit to set Alternate TFTP to On/Yes and configure TFTP Server 1 to 3.14.211.49. It is important to note that this static IP address could change, so reference the address specified on upgrade.cisco.com as it will have the latest information.

To enter these numbers, you will either have a dot button connected to the star key, or you will need to click the large circular button on the phone for the octets to show for the address. This depends on your model of phone. Select Validate.

Step 3

Select Apply.

Step 4

Select Erase if prompted that a Trust List is installed on the phone.

Step 5

Wait for the phone to download the configuration and upgrade/restart several times.

Hello! Please have a look at the steps given under  'Manual migration (Lab/PoC/Several devices)'

(Note: If the IP address isn't working, try using the IP address obtained from 'ping cloudupgrader.webex.com')

Assuming that you're migrating these phones to Webex Calling, you can utilize the tool within Control to Migrate your devices.

Things to check, is your device on the minimum firmware, is your device supported ( v04 and above)

That help article appears to assume CUCM is still around. You may also want to look at the Cloud Upgrader site under the Enterprise to MPP conversion process. There is a manual option with an alternate TFTP IPv4 address you can use there to help the phone get over to MPP. It'll still need a migration license from WCH though - which is the help article @keclair shared.
