Separate Calling Party Number and Billing Number in SIP

External Presentation Name and Number Overview

Cisco Unified Communications Manager Administration can be configured to contain separate calling party and presentation number.

In previous releases, Cisco Unified Communications Manager cannot be configured on a per line basis to have a different number sent to the PSTN in the FROM and PAID header. If a group of users is configured to present the same Calling Line Identification Number to PSTN users, which is a nongeographic E.164 number and cannot be used for billing. Therefore, the users actual DDI must be sent in a different field than the presentation number. With this release, Cisco Unified Communications Manager supports External Presentation Name and Number that is different from existing Identification Name and Number. The configured Presentation Name and Number are for display purpose on the following devices:

  • SIP

  • SCCP

  • Single Number Reach Destination (SNRD)

  • CTIRD

  • SparkRD

Configuration Overview

You can configure the external presentation name and number feature on the following pages:

  • Directory Number Configuration

  • SIP Profile Configuration

  • Trunk Configuration


Note

  • When you configure the External Presentation Information on the SIP Profile Configuration page, the value of External Presentation Number and External Presentation Name on the SIP Profile Configuration page is used, overriding the settings configured on the Directory Number page.

  • When you configure the Presentation Information on the Trunk Configuration page, the value of Presentation Number and Presentation Name on the Trunk Configuration page is used, overriding the settings configured on the SIP Profile Configuration and Directory Number Configuration pages.

Call Processing

This section describes the incoming and outgoing call behavior when you configure the external presentation name and number feature.

Incoming Call Process

Cisco Unified Communications Manager looks for FROM and PAID header information when there is a call initiated from the PSTN network. The FROM header contains the external presentation name and number (if configured). However, this is not the real identity of a user, it is used only for display purpose. The PAID header contains the identity (original DN or DDI) of the user.

If FROM and PAID headers have different numbers and Enable External Presentation Name and Number option is enabled in the SIP Profile Configuration page and Display External Presentation Name and Number service parameter value is set to True, then Cisco Unified Communications Manager displays the FROM header information (configured external presentation name and number) on the called device. Similarly, if an option is disabled, Cisco Unified Communications Manager displays PAID header information (user's original DN or DDI) on the called device.


Note

  • By default, Enable External Presentation Name and Number field is unchecked.

  • Default value of a service parameter Display External Presentation Name and Number is False.

Invite Received from the PSTN Network


From: "Customer Care" <sip:1800000@example.com>;
To: <sip:someone@example.com>
P-Asserted-Identity: "Your personal adviser <sip:user1@example.com>
Remote-Party-ID: "Your personal adviser <sip:user1@example.com>

In the preceding example, FROM header contains a number different from the PAID header. If you check Enable External Presentation Name and Number check box and set Display External Presentation Name and Number value to True, Cisco Unified Communications Manager displays Customer Care / 1800000 on the called device.

If you uncheck the Enable External Presentation Name and Number check box or set the Display External Presentation Name and Number to False, then Cisco Unified Communications Manager displays Your personal adviser / user1@example.com on the called device.

Outgoing Call Process

Let us assume, a user configured with External Presentation Name and Number initiates a call to a PSTN network through the SIP trunk with Enable External Presentation Name and Number configured in its SIP Profile. Then, Cisco Unified Communications Manager sends the configured External Presentation Information in the FROM header of the outgoing SIP message and displays on the called device.

If Enable External Presentation Name and Number option is disabled or External Presentation Number and External Presentation Name fields are not configured, the Cisco Unified Communications Manager sends the directory number information in the FROM and PAID headers and displays on the called device.

External Presentation Number Mask Operation

Cisco Unified Communications Manager allows you to mask the external presentation number, to be displayed on the called device. You can mask the presentation number on the Directory Number Configuration, SIP Profile Configuration, and Trunk Configuration pages.

When you enter the digits in the External Presentation Number field with trailing X, the value of X is replaced with the directory number information starting from right to left.

Mask Operation on Directory Number Configuration

If you mask External Presentation Number as 180011XXXX on Directory Number Configuration page for a Directory Number 5551234, then Cisco Unified Communications Manager displays the presentation number as 1800111234 on the called device.

Mask Operation on SIP Profile Configuration

Let us assume External Presentation Number on Directory Number page is 180011XXXX and if you mask External Presentation Number on SIP Profile Configuration page as 180022XXXX for a Directory Number 5551234, then Cisco Unified Communications Manager displays the presentation number as 1800221234 on the called device.

Mask Operation on Trunk Configuration

Let us assume External Presentation Number on Directory Number page is 180011XXXX and on SIP Profile Configuration page is 180022XXXX. If you mask Presentation Number on Trunk Configuration page as 180033XXXX for a Directory Number 5551234, then Cisco Unified Communications Manager displays the presentation number as 1800331234 on the called device.

Directory Number Overview

In Cisco Unified Communications Manager Administration, use the Call Routing > Directory Number menu path to configure Directory Numbers (DNs). Using Cisco Unified Communications Manager Administration, you can configure and modify the DNs that are assigned to specific phones.

A new section External Presentation Information is added on the Directory Number Configuration page. The administrator can now configure the presentation name and number of their choice to display on the supported devices for external calls. If an administrator does not want to show users' identity, they have a privilege to display configured External Presentation Number and External Presentation Name as Anonymous on the called party device.

Intercluster SME Call Flows

The Cisco Unified Communications Manager Session Management Edition software is same as the Cisco Unified Communications Manager used mainly for a call routing between clusters or various devices. With this release, Cisco Unified Communications Manager supports the intercluster SME calls.

Incoming Calls

Let us assume a user from a PSTN network initiates a call with Enable External Presentation Name and Number enabled in its SIP profile. If Display External Presentation Name and Number service parameter is set to True, then Cisco Unified Communications Manager sends the presentation number information to the X-Cisco-Presentation header and displays on the called device. The FROM and PAID headers contains the identity of the user that is the user's DN or DDI.

If Display External Presentation Name and Number service parameter is set to False, then Cisco Unified Communications Manager sends the presentation number information to the X-Cisco-Presentation header. The FROM and PAID headers contains the user’s DN or DDI and displays on the called device.

Outgoing Calls
A user who is configured with External Presentation Name and External Presentation Number initiates a call to a PSTN network through intercluster SIP trunks. If Enable External Presentation Name and Number check box is disabled in its SIP profile, then, Cisco Unified Communications Manager sends the original directory number information in the FROM and PAID headers and displays on the called device and configured External Presentation Information in the X-Cisco-Presentation header. Similarly, if Enable External Presentation Name and Number check box is enabled in its SIP profile, Cisco Unified Communications Manager sends the configured External Presentation Information in the FROM header and displays on the called device and original Directory Number in the PAID header.
