The Business Communications Manager 3.5 system performs QOS routing, but if one or more

routers along the network route do not support QOS routing, this can impact voice quality.

Business Communications Manager 3.5 system QoS can also be configured so that the system

reverts to a circuit-switched line if a suitable QoS cannot be guaranteed.
