Preemption Rules
•
Voice calls always preempt data.
•
Voice always preempts data if two B-channels are used for the same
destination.
•
Call preemption does not occur on incoming calls unless a person
picks up the phone or the analog equipment answers the call.
•
An incoming voice call may not always be forwarded from the
central office if two B-channels are already in use for data calls.
You must subscribe to a service called “Additional Call Offering” for
the voice call to be forwarded to the router.
