ISDN Numbering Calling Party Number Conversion for
Tandem Calls
Tandem calls that route to the public network cannot always provide the correct calling party
information, resulting in loss of caller ID information. Communication Manager provides a way
of modifying the calling party number on a tandem call that lands in the public network.
Use the Calling Party Number Conversion for Tandem Calls screen to administer calling
party number formats for tandem calls. To generate a calling party number for the public
network, the system compares the incoming calling party number to the sets of calling party
lengths, calling party prefixes, and trunk groups. When a match is found, the calling party
number is constructed by deleting digits identified in the Delete field on the Calling Party
Number Conversion for Tandem Calls screen, and then inserting the digits specified in the
Insert field. The numbering format specified in the Format field is used to determine the
encoding of the NPI and TON fields for the calling party number.
Entries on this screen are only exercised if the Modify Tandem Calling Number field on the
ISDN Trunk Group screen is set to y. To access the Calling Party Number Conversion for
Tandem Calls screen, type change tandem-calling-party-number. Press Enter.
