Phones and Voice Applications

Most external applications emulate 5220 sets and require similar resources when they connect
to the 3300 ICP. They will also use sockets and place monitors on the users’ sets, similar to
the MiCollab Clients and server in the above tables.
The UC Express application connects to the phone for access to call control. All of the UC
Express supported phones have a SAC connection, but may not invoke a monitor. When UC
Express is connected, all of the supported phones will invoke a monitor, due to the added
application support.
Although resilient devices may not consume resources immediately, these should still be
provisioned to cover the possibility of these devices being active during resilient operation.
Note: A hot desk phone will consume resources as required by the phone. A hot-desk
user that is not logged in to a phone will consume a monitor resource within the SAC
application. When a user logs into a phone, that user monitor will take over control,
replacing the phone monitor, thereby reducing the number of active monitors. The worst
case condition is therefore hot desk phones without any users logged in.
