Avaya MultiVantage supports sending a non-ISDN trunk name as the connected
name. Therefore, a non-ISDN trunk name can be sent as the connected name even
when a call starts out as an ISDN call but is interworked over non-ISDN trunks.
Call Identification Display
Two types of identification numbers are provided with ISDN and may be used in
the various types of displays used with ISDN. The two types of identification
numbers are as follows:
■ Calling Party Number (CPN): A 0–15 digit DDD number associated with a
specific station. When a system user makes a call that uses ISDN, that
user’s CPN is provided by the system for ISDN. ISDN public-unknown
numbering or ISDN private numbering screens are administered to create a
0–15 digit CPN from a local station number.
■ Billing Number (BN): The calling party’s billing number, which is
provided to an inter-exchange network via Equal Access or CAMA. This
number is stored at either a local or network switch. If a customer is
connected directly to the AT&T Switched Network, the BN is the
customer’s billing number stored in that network. If the CPN is not
provided on an incoming ISDN call, the network uses the BN for the
station identification number.
The following types of display information are provided with ISDN:
■ Calling Party’s Number
The calling party’s number appears on the called party’s display. This
number is provided only if the outgoing ISDN trunk group is administered
to send the CPN, and if ISDN public-unknown numbering or ISDN private
numbering screens are administered to create a CPN. On calls incoming to
a system, the network may provide either the CPN or BN as the calling
party’s number. Extensions and 12-digit international numbers display
without dashes. Dashes are only used for 7-digit and 10-digit numbers
when North American Area Code is enabled on the Dial Plan screen.
