Station priority

Introduction
You can define a MIG RLC port to which a station is assigned as normal
priority, high priority, circuit-switched only, or IP only.
Normal priority
When both the IP and circuit-switched networks are used to route calls, calls to
and from the station are routed primarily over the IP network (if the IP network
is used to route calls). Calls transition between the IP and circuit-switched
networks whenever voice QoS levels change. (The voice QoS levels are defined
on the Quality of Service screen on the MIG RLC for your Remote Office 9150
unit.)
High priority
When both the IP and circuit-switched networks are used to route calls, calls to
and from the station are routed primarily over the IP network. Calls transition
between the IP and circuit-switched networks whenever voice QoS levels
change. (The voice QoS levels are defined on the Quality of Service screen on
the MIG RLC for your Remote Office 9150 unit.)
When the priority reservation setting is also defined on the connection between
the MIG RLC and the Remote Office 9150 unit, the following benefits are
provided:
If allowed to use the IP network to process calls (this is transparent to the
user), an active call on that station is always one of the first to be
transitioned to PSTN trunks when Voice over IP QoS has degraded. (This
transition is accomplished using the QoS transitioning technology.)
Call blocking is reduced because bandwidth is always available to these
stations.
Note: If the reserved bandwidth is being used by other high priority
stations, then new calls are processed using unreserved bandwidth.
