Introduction
This document describes how to configure a Cisco Microsoft Teams Room (MTR) device to join 3rd party meetings.
Prerequisites
Requirements
Cisco recommends that you have knowledge of these topics:
- Knowledge of onboarding Cisco endpoints to MTR.
- Knowledge of Microsoft PowerShell
Components Used
The information in this document is based on these software and hardware versions:
- Cisco Codec Pro September Stable version, fully onboarded into Microsoft Teams as an MTR device (or dual registered with Webex Control hub).
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
Background Information
When your Cisco device is set up in MTR mode, only meetings for Microsoft Teams are presented with a join option by default. In order to see join buttons for Webex or Zoom meetings, there are some additional steps needed achieve this. Without performing these steps, the display can show meeting information without a join option or show no meeting details at all.
Configure the Device and Resource Mailbox
Device Configurations
There are two considerations for device configurations:
1. The resource account must be able to process the third-party meeting invite.
2. The device must be enabled to join third-party (Webex and Zoom) meetings.
For point 2, there is a setting on the device when it is running the MTR experience that you need to toggle to On to allow it to show the Join button for Webex and Zoom meetings.
To locate and change this setting:
- Navigate to the Home screen of the MTR device.
- Navigate to More > Teams admin settings.
- By default, the MTR settings are locked, so they must be unlocked first. If the device is in MTR Only mode, the password is created by the administrator during setup.
Device Settings Teams Admin Settings
- If the device is dual registered (Teams and Webex Control Hub), unlock the settings menu from the Control Hub under All > UserInterface > SettingsMenu > Mode > Cisco Room Bar and select Unlocked.
Control Hub Device Settings Menu
- With the settings menu unlocked, navigate to Meetings > Third party meetings and enable Webex and/or Zoom:
Settings Menu - MTR
Resource Mailbox Configurations
To change the calendar processing attributes in Office 365, an exchange admin must connect using PowerShell and issue this PowerShell command:
PowerShell command:
Set-CalendarProcessing -Identity “[ResourceName]” -AutomateProcessing AutoAccept -AddOrganizerToSubject $false -DeleteComments $false -DeleteSubject $false -ProcessExternalMeetingMessages $true -RemovePrivateProperty $false -AddAdditionalResponse $true - AdditionalResponse "This Is a Microsoft Teams Meeting room powered by a Cisco collaboration device!”
Some of these settings are suggested values. With regards to processing third-party meetings, the most important attributes here are DeleteComments $false and ProcessExternalMeetingMessages $true. The other attributes can vary based on your organization's preferences.
Troubleshooting
See the Meeting Invitation but no Join Button
If you see the invite on the device but no join button, check that the mailbox settings in Exchange are correct. Specifically, check calendarProcessing > DeleteComments.
This value must be false, but by default is set to true when creating new resource mailboxes.
Also, third-party meeting support in the Settings > Meetings menu must be enabled.
Cannot See the Meeting Invitation
If the third-party meetings are not showing at all, then it is likely that the resource mailbox is not processing the invite. Check this resource mailbox calendarProcessing configurations:
- DeleteComments must be set to false.
- ProcessExternalMeetingMessages must be set to true.
