Call by Call service selection for PRI
PRI lines can be dynamically allocated to different service types with the Call by
Call feature. PRI lines do not have to be pre-allocated to a given service type.
Call types that may be available, depending on your service provider are:
Public
Public calls connect your Enterprise Edge set with a Central Office (CO). DID and
DOD calls are supported.
Private
Private calls connect your Enterprise Edge set with a Virtual Private Network. DID
and DOD calls are supported. A private dialing plan may be used.
Tie
Tie lines are private incoming and outgoing lines that connect Private Branch
Exchanges (PBX) such as Enterprise Edge.
FX (Foreign Exchange)
FX calls connect your Enterprise Edge set to a remote CO. It provides the
equivalent of local service at the distant exchange.
Outwats
Outwats is for outgoing calls. This allows you to originate calls to telephones in a
specific geographical area called a zone or band. Typically a flat monthly fee is
charged for this service.
Inwats
Inwats is a type of long distance service which allows you to receive calls
originating within specified areas without a charge to the caller. A toll-free number
is assigned to allow for reversed billing.
Consult your customer service representative to determine whether or not this
feature is compatible with your provider.
Dialing Plan and PRI
The Dialing Plan supports PRI connectivity to public and private networks. The
dialing plan is a collection of features responsible for processing and routing
incoming and outgoing calls. All PRI calls must go through a dialing plan.
The Dialing Plan
• allows incoming calls to be routed to sets based on service type and digits
received
• allows Enbloc dialing by buffering user-dialed digits until a complete DN has
been dialed
• provides the ability to map user-dialed digits to a service type on a Call by Call
basis
