Azure MMR Integration System Requirements
Prerequisites
To use Azure (Entra) Virtual Optimization with 8x8 Work for
Desktop and Web, you must meet Microsoft's prerequisites.
Note: Multimedia redirection isn't supported on Azure
Virtual Desktop for Microsoft 365 Government (GCC), GCC-High environments, and
Microsoft 365 DoD.
Whitelisting the Application
After installing multimedia redirection on session hosts,
you have to enable the optimization for 8x8 Work Web or Work Desktop.
To enable Work for Web:
IT Administrators must enable call redirection for 8x8
domains. In the Azure environment, IT Administrators need to add the following
registry keys:
If
the browser used is Edge add the following key:
If
the browser used is Chrome add the following key:
Regardless
of whether you are using Chrome or Edge add the following:
To enable Work for Desktop:
The Azure redirection feature must be enabled on the Work
Desktop side by setting a config flag via `8x8work-config.json` or
`AppConfig.ini`.
To enable the Azure MMR redirection optimisation using the
8x8work-config.json file add the following config in the file:
To enable the Azure MMR redirection optimisation using
AppConfig.ini add the following config in the file:
To create the ‘8x8work.config.json’, IT administrator has to
create a .json file in the Azure environment.
Path for .exe installer:
root:\Users\<user>\AppData\Local\8x8-Work\8x8work-config.json
Path for .msi installer: C:\Program Files\8x8 Inc\8x8
Work\8x8work-config.json
Network Firewall Changes
Thin clients or the endpoints used to connect to the Azure
sessions require a network environment that doesn't block the traffic to the
8x8 data centers, as with the optimization, the voice path is offloaded to the
endpoints. See
X Series Technical
Requirements.
Network Traffic and Routing
RTP
(voice traffic) will egress from the local machine when MMR optimization
is enabled, not from the Azure Virtual Desktop.
DNS
Queries will be performed on the Azure Server, where the application runs.
Please take this into account when troubleshooting. DNS queries issued
from the Azure Server may cause discrepancies in the 8x8 Global Reach
Traffic Routing due to the Client's physical location compared to the
Azure VDI Server.
Checking Optimization
You can check if Azure optimization has been activated
inside the app by checking the following indicators:
Log
in to 8x8 Work for Web.
Select the
MMR extension icon in the upper-right corner.
Confirm
that Call Redirection has a green checkmark.
Make
sure the Enable call redirections for all sites setting
is toggled on (blue).
Local Audio Devices
Within the app, check Call using dialog and assert Computer
- Azure MMR is showing.
Important Notes
The Operating System microphone permission may prevent the
8x8 Work Desktop app from accessing the microphone. Ensure the app has mic
permissions.
Known Limitations
This
optimization is focused on VoIP / telephony only at this moment. Video
Meetings optimization is not supported at the moment.
UC
headset call controls are not supported when running in Azure VDI.
3-way
calls are not supported in 8x8 Work for Desktop and Web while the Azure
optimization is active.
