Numbering — Public/Unknown Format

Last Updated : Jun 17, 2019 |

Use this screen to specify the required digits for the Calling Number Information Element (IE) and the Connected Number Information Element (IE), in addition to the QSIG Party number, for any extension in Public and/or Unknown Number Plans. Use this screen for Automatic Route Selection (ARS) public trunks as well as SIP trunks. This screen supports the ISDN Call Identification Display feature. This feature provides a name and number display for display-equipped stations within an ISDN network. The system displays the name and number of the caller on the telephone display of the called party and displays the name and the number of the called party on the telephone display of the caller.

You must administer this screen if either Send Calling Number or Send Connected Number is specified, or Supplementary Service Protocol is b on the Trunk Group screen.

You must administer the following in the public numbering table on the Numbering-Public/Unknown Format screen:

  • Extensions of all calls traversing SIP trunks

  • Extensions terminating on SIP integrated Modular Messaging. However, do not configure a prefix for the SIP trunk group by which the Modular Messaging is integrated.

Note:

If an entry applies to a SIP connection to Avaya Aura® Session Manager, the resulting number must be a complete E.164 number. Communication Manager automatically inserts the plus (+) digit.

You can use the following command to modify the fields on this screen:

change public-unknown-numbering n, where n is the extension length from 0 to 16.

CPN Prefix

Use this field to enter the number that is added to the beginning of the extension to form a Calling Party Number (CPN) number.

You must enter only digits. You cannot enter leading spaces, or spaces in between the digits. You can enter up to 15 digits. Communication Manager formulates the CPN number in the following manner:

  • If the length of CPN Prefix matches Total CPN Length, the extension number is not used to formulate the CPN number.

  • If the number of digits in CPN Prefix plus the extension length exceeds the administered Total CPN Length, Communication Manager deletes excess leading digits of the extension when formulating the CPN number.

  • If the number of CPN Prefix digits plus the extension length is less than the Total CPN Length, Communication Manager does not allow the entry.

  • If the Total CPN Length is 0, no calling party number information is provided to the called party and no connected party number information is provided to the calling party.

Note:

If you leave this field blank, the extension is sent unchanged.

Ext Code

In the case of a four-digit Ext Len, an Ext Code of 12 is the equivalent of all extensions of the screen 12xx, excluding any explicitly listed longer codes. If a code of 123 is also listed, the 12 code is equivalent of all extensions of the screen 12xx except extensions of the screen 123x. The coding precludes having to list all the applicable 12xx extensions.

Valid Entry

Usage

0 to 16

blank

Accepts up to 16 digits depending on the administered extension length. When 0 alone is entered, the administered extension length must be 1 and the DDD number must be 10 digits.

attd

Generates a private calling number for a call from the attendant group.

Ext Len

Valid Entry

Usage

0 to 16

blank

The number of digits the extension can have.

Corresponds to the extension lengths allowed by the dial plan.

Total CPN Len

Valid Entry

Usage

0 to 15

The number of digits the extension can have.

blank

Used when deleting an entry. This is the default.

Trk Grp(s)

Communication Manager generates the station’s identification number if Ext Code is administered, and this field is administered with the trunk group number carrying the call. Accepts one to seven digits. If blank, the identification numbers are independent on the trunk group carrying the call.
