Introduction

This document describes how to disable the encrypted HTTP connection between TMS and MCU. This is useful when troubleshooting a booking related issue and you want to capture the actual packets for API exchanges between TMS and MCU. Signaling and media encryption will not be disabled by this.

 

 

TMS Settings

For TMS version 14.X and earlier

1. Login to TMS Web UI as an administrator, and 

2. Go to Administrative Tools > Configuration > Network Settings > Secure-Only Device Communication, and set "Secure-Only Device Communication" to off.

3. Save the change

 

For TMS 15.X and later

1. Login to the Windows Server that hosts TMS as a user with administrative privileges

2. Run Start > Programs > Cisco TelePresence Management Suite > TMS Tools

3. Go to Security Settings > Advanced Security Settings > Transport Layer Security Options, and set "Communication Security" to Medium

4. Save the change

TMSSnmpService and TMSPLCMService services are automatically restarted.
