2.29 Workgroup
You can configure Bria to display information about users in a workgroup. Only Bria for Windows supports
workgroup. Workgroups implement functionality also often associated with BLF (Busy lamp field) and BLA
(Bridged line appearance).
A workgroup is a group of people who work together. Via the Bria Workgroup window, members of a
workgroup can monitor each others’ calls, pick up on behalf of another member, and join an established call.
Workgroups can be set up in two ways:
• In server mode by integrating with an RLS application. In this mode, workgroups can be set up through
remote provisioning or they can be set up by each user, on the Account > Presence tab.
• In peer-to-peer mode. In this mode, each Bria endpoint subscribes to other Bria endpoints. The feature is set
up entirely within each individual Bria; there is no server component. Peer-to-peer workgroups are set up
by each user; they cannot be set up through remote provisioning.
In both modes, ach member of the workgroup can be set up as:
• A regular member: every member monitors and is monitored by everyone else.
• Or as a supervisor: the supervisor monitors but is not monitored by other members.
Configuring in RLS Mode
In RLS mode, workgroups are implemented through support of dialog events (RFC 4235) and through
subscription to a “resource list server” (RLS) in accordance with RFC 4662. The workgroup feature uses full
updates (not partial updates) for dialog events.
The server application (your PBX that includes workgroups or the workgroup application) must support RFC
4235 and RFC 4662. Bria does not support resource list subscriptions for the “presence” event package.
How Workgroup Works
Here is a typical implementation. The RLS application is set up with one or more resource lists. Each list has its
own URL. Each list contains the URIs (extensions) of people who are considered to be in a workgroup and can
therefore monitor each other.
On the Bria side, each user is set up with the URI of the resource list they belong to. Each user is also set up to
allow monitoring by other users.
When the SIP account becomes registered, Bria automatically contacts the RLS with the URL of the specified
list. The RLS sends out subscription requests to all the URIs in the list. Each online user automatically responds
to the request. When responses are received, the RLS sends status information to the requesting user.
When all the “online” (SIP account is registered) users in the workgroup do this, the result is that each user is
able to monitor the activity of every other online member of the list.
One variation on this setup is for supervisors. The setup is identical except that the supervisor is not set up to
allow monitoring by other users. When the supervisor goes online, their requests to monitor other people in the
list will be accepted, but requests from other people to monitor that supervisor will be blocked. The result is that
the supervisor is able to monitor the activity of everyone in the list but no-one can see the supervisor.
How to Set up
1. On the RLS application, create the resource list or lists and add the appropriate people. Each list has a name
such as “sip:[email protected]” or “sip:[email protected]”.
