Defect Information

Defect ID	Headline
CSCwf99961	Navigator in MTR mode responses slow

Problem Description

Cisco Room Navigators may perform slowly or become unresponsive when they are running Microsoft Teams Rooms.

Background

Cisco has identified user interaction performance issues in a specific batch of Cisco Room Navigators while they are running Microsoft Teams Rooms, such as slow performance on menu and call control.

This issue does not impact customers who are using Cisco Room Navigator to run Cisco RoomOS with Cisco Webex Software, Cisco Unified Communications Manager (Unified CM), Cloud Video Interop (CVI) for Microsoft Teams, or Web Real-Time Communications (WebRTC).

Problem Symptom

Right-swiping to the control menu on Cisco Room Navigators can take up to four to five seconds, and actions in the Microsoft Teams Rooms application while using Cisco Room Navigators can take a substantial amount of time to respond. This condition can occur when Cisco Room Navigators are used for the first time, when they are rebooted, or after they have been dormant.

Workaround/Solution

If symptoms on an affected Cisco Room Navigator substantially degrade the end-user experience, Cisco recommends replacing the device with the most current Cisco Room Navigator version, which will improve the user experience.

There may be a slight color difference between earlier versions and the most current version of Cisco Room Navigator.

The replacement product identifiers (PIDs) for this Field Notice will be applied when replacement orders are created. One of the following PIDs will be used for the replacement:

CS-T10-TS-L-K9= (table-stand Navigator)
CS-T10-WM-L-K9= (wall-mount Navigator)

How to Identify Affected Products

For an affected Cisco Room Navigator to be eligible for replacement, the following conditions must be met:

Cisco Room Navigator is running Microsoft Teams Rooms.
The PID is listed under Products Affected in this Field Notice.
The serial number of the Cisco Room Navigator device will be validated by the Cisco Technical Assistance Center (TAC).

Customers who are experiencing slow Cisco Room Navigator performance while it is running Microsoft Teams Rooms but whose device does not satisfy all of the above requirements should reach out to the Cisco TAC for immediate support. The Cisco TAC will provide the necessary guidance and assistance to address this issue.
