Feature description

Call Forward Busy (CFB) automatically routes incoming Direct Inward

Dialing (DID) calls to the attendant console when a telephone is busy.

This capability is allowed or denied in the Class of Service (FBA/FBD) of

the telephone.

Operating parameters

On incoming DID calls, Hunting takes precedence, followed by Call Waiting,

then Call Forward Busy. In busy situations, the call hunts if the telephone

has Hunting speciﬁed.

Feature interactions

Attendant Alternative Answering

If Call Forward Busy is allowed for the Attendant Alternative Answering

(AAA) DN (and that DN is busy), a DID call is returned to the attendant and

can again be eligible for AAA timing and operation.

Attendant Busy Verify

Attendant Busy Verify does not affect Call Forward Busy.
