Converting Cisco Phones from Enterprise to MPP
Posted by Freddy Tabet

Whether you’re migrating from On Prem Call Manager to WebEx Calling, Spark to WebEx Calling or just have some old phones you want to add to your WebEx Calling Deployment; you will need to convert your phones from their Enterprise Firmware to the cloud supported MPP firmware.

First you need to go over the steps needed to convert the phones to MPP and make sure that you have all bases covered. There’s nothing worse than starting the task and then realizing halfway that those phones won’t work.

Below is a highlight of the actions needed:

  • Check WebEx Calling supported phone models and hardware revision to make sure that the phones will work in a WebEx Calling Deployment.

  • Make sure those phones are running the minimum firmware version required to convert them to the MPP firmware

  • Network Requirements

  • Verify that you have access to the WebEx Control Hub.

  • Make sure you have Webex Calling Licenses.

  • Migration Methods: CUCM Registered Phones vs DHCP (Staging Phones)

  • If you’re phones are not currently registered to a Call Manager, you need access to your DHCP server to setup a few parameters.


  1. Devices Support for Firmware Conversion

IP Phones Supported for Conversion

7800 Series

8800 Series

Conference Phones





ATA 191



8832 (8831 Not Supported)

ATA 192


















  • 7821 & 7861 requires a V03 or later hardware to convert to MPP.

  • 7841 requires a V04 or later Hardware version to convert to MPP

  • You can check the label on the back of the phone to find your version (VID).

II. Phones Minimum Version

A. Call Manager Registered Phones

If the phones are running an older version then follow the below steps:

  1. Go to CUCM Administration → Device →Phone

  2. Scroll download to Phone Load Parameter and enter the phone load that is relative to your phone type

    3. Scroll further down to Load Server and enter cloudupgrader.webex.com

If the phones are running an older version, then you need to upgrade the firmware using a DHCP/TFTP server.


III. Network Requirements

If you are using a firewall only, note that filtering traffic using IP addresses is not supported, as the IP addresses used by Cloud Upgrader are dynamic and may change at any time. If you firewall supports URL Filtering, whitelist the following URLs:

  • Cloudupgrader.webex.com, ports 6970/443
  • Activate cisco.com, ports:443
  • Activation.webex.com, ports:443
  • *.wbx2.com, ports 443.

Note that WebEx Calling have other ports and network requirements to successfully register your phones to WebEx Calling, check them out below:


Other Network requirements are DNS, Internet connectivity from Voice VLAN and DHCP Options (if you’re using the Staging Phones migration method).
