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.
