Calling Number – Delete
Calling Number – Insert
Calling Number – Numbering Format
This field indicates the TON/NPI encoding applied to CPN information modified
by the CLI Prefix feature. This encoding does not apply to calls originating
locally. The Numbering Format field on page 2 of this screen applies to calls
originated from this switch.
If this field is blank, DEFINITY ECS passes on the encoding received in the
incoming setup message. If the incoming setup message did not contain CPN
information and digits are added, the outgoing message will contain these digits.
If the Numbering Format field is blank in this case, the value defaults to pub-unk.
If the Numbering Format field on page 2 of this screen is also administered as
unknown, the trunk group is modified to “unk-unk” encoding of the TON/NPI.
Therefore, this field also must contain a value other than
unknown.
NOTE:
The values for this field map to the Type of Numbering (TON) and
Numbering Plan Identifier (NPI) values shown below.
