Configuring Per User Role Lync/Skype for Business Call Prioritization
In AOS-W 6.3.x, you can configure the UCC call prioritization system-wide only. For example, Lync/Skype for
Business voice, video, and collaboration applications can be configured system-wide on the switch. Starting
with AOS-W 6.4, an administrator can configure Lync/Skype for Business call prioritization on a per user-role
basis. With this feature, you can have one set of users have priority on real-time media traffic over another set
of users. An administrator can configure the per user-role Lync/Skype for Business call prioritization based on
the deployment needs.
Important Points to Remember
If two clients in an active call are in different user-roles and traffic prioritization, the traffic prioritization is
based on the following order:
1. Voice
2. Video
3. Best-effort
4. Background
The above is applicable for both; the caller and called parties.
Example
Client 1 (C1) is assigned user-role 1 with voice priority enabled. Client 2 (C2) is assigned user-role 2 with voice
priority disabled. When C1 makes a voice call to C2, both parties have prioritized voice call.
Traffic prioritization may not apply if it is a conference call or the caller and called parties are in multiple switches.
You can configure the per user-role UCC call prioritization for Lync/Skype for Business ALG using the WebUI or
CLI.
In the WebUI
Configure the Lync/Skype for Business traffic control profile:
1. Navigate to the Configuration > Advanced Services > All Profiles page.
2. Select Other Profiles to expand the Other Profiles section.
3. Click the Traffic Control Prioritization profile.
4. Under the Traffic Control Prioritization Profile section, enter the profile name and click Add.
