- The device now supports Microsoft's proprietary SIP header X-MS-UserSite, which is used for Local Media Optimization in Microsoft's Teams environments. This header, which is present in the SIP message received from the Teams client, indicates the Teams site (name) within which the Teams client is located. Based on this header, the device can now determine if the path (connectivity) between the Teams clients is good for voice quality and thus, intended for direct media calls.
The following configuration has been updated due to this support:
- The device's handling of Teams calls to determine direct media has been updated regarding the existing IP Group's 'Teams Local Media Optimization Handling' parameter. For more information, refer to the User's Manual.
- For determining if the path is good for voice quality and thus, intended for direct media, the device uses the following mechanism:
• A new parameter 'Teams Local Media Optimization Site' has been added to the IP Groups table to define the name of the Teams site (e.g., "Singapore"). For each IP Group representing specific Teams clients, this parameter is configured accordingly with the site's name.
• A Dial Plan is used to determine if the path between the Teams clients is intended for direct media. The Dial Plan is specified by the new parameter 'Region Connectivity Dial Plan'. Each Dial Plan rule in the Dial Plan is configured with a Teams site name in the 'Prefix' parameter (e.g., "Singapore") and with logical
group(s) to which the Teams site belongs in the 'Tag' parameter (e.g., "Group=2,7"). When the device receives the SIP dialog from a Teams client, it checks the Dial Plan to see if the Teams sites of the source and destination Teams clients share a common group number. If they do, the device considers the call as direct media.
