Webex Teams Calling Cucm

The first option is purely cloud based ie Webex Teams app uses whatever webex calling plans you have, Ie if you have Webex calling (with Local gateway) enabled you can still make calls to CUCM and PSTN. The second option registers your webex teams app to CUCM as a CSF device. Can also leverage MRA to register off premise.

Introduction

This document describes an issue where Webex is not able to place calls when it is paired to an on-premise registered device via proximity.

Problem: Webex Unable to Place Calls when it is Paired to an On-Premise Registered Device

When you attempt to make an outbound call or join a Webex meeting from Webex app, while it is paired to an on-premise device, Webex throws the error 'This device does not allow you to start calls or join meetings using your Webex app. Try placing the call directly from the device.'. Steps to reproduce the problem are described here:

Step 1. The Webex app successfully pairs to the device as shown in the image:

Step 2. When the meeting becomes available to join, click the Now button to launch the join screen as shown in the image:

Step 3. Verify the device is selected and click Join Meeting as shown in the image:

Step 4. After you click on Join meeting you are presented with an error as shown in the image:

If you need these error collect logs from the Webex app for analysis.

Location of log files for Webex Application is:

Windows: %USERPROFILE%AppDataLocalCiscoSpark

Solution

This issue occurs when CallControl under Proximity settings is not enabled. You should enable CallControl under the Proximity settings of the device. This can be achieved with one of these options:

Option 1. The GUI of the Device

Log in to the endpoints GUI and Navigate to Setup > Configuration > Proximity and enable CallControl as shown in the image:

Option 2. CUCM if the Device is Registered to CUCM
