Cisco Webex Board Pro 55 G2 CUCM registration

[johnmontgomery101]

I am trying to register a new Cisco Webex Board Pro 55 G2 in CUCM version 14SU2

I am getting SIP registration Failed 485 Ambiguos / Device type mismatch

I have tried to register the device as a:

Cisco Webex Board 55

Cisco Webex Board Pro 55

Cisco Webex Room 55

All get the same errors, the device is showing the SIP URI, provisioning is showing my CUCM IP correctly and I can make certain changes within CUCM that affect the device, such as CAPF and Web access etc.

has anyone else come across this problem and do you know which Phone Type (and Protocol) I am to use for this device?

Looking through the logs, it says the phone is type 36351, how do I relate that to the device type name?

You need to add the device as Cisco Board Pro 55 G2 as seen in this picture.

If you do not have this device type available you'll need to install a device pack to get the device added to the system.

You'll need this device pack or later to get the G2 models. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/device_packs/1401-devpack-for-may-2024.html
