4.10 Translating Numbers From/To E.164 Using Manipulation
Tables for PBX/PSTN Connectivity
The Manipulation tables provide the ability to translate (normalize) numbers dialed in standard
E.164 format to various formats and vice versa. Manipulation is necessary for your dial plan as
Lync 2010 uses the standard E.164 format while your PBX or PSTN implements other number
formats for dialing.
Due to Lync 2010 normalization rules, the Media Gateway may need to perform number
manipulation for outbound calls (i.e., calls received from OC clients/endpoints through Lync 2010)
and inbound calls (i.e., calls destined for OC clients). If the Media Gateway is connected to a PBX
or directly to the PSTN, the Media Gateway may need to perform number manipulations for the
called and/or calling number to match the PBX or PSTN interfaces dialing rules or to match Lync
2010 E.164 format.
4.10.1 Manipulation Tables
The Manipulation Tables submenu allows you to configure number manipulation and mapping
of NPI/TON to SIP messages. The number manipulation rules are configured in the following
tables:
For Tel-to-IP calls:
• Destination Phone Number Manipulation Table for Tel-to-IP Calls
• Source Phone Number Manipulation Table for Tel-to-IP Calls
For IP-to-Tel calls:
• Destination Phone Number Manipulation Table for IP-to-Tel Calls
• Source Phone Number Manipulation Table for IP-to-Tel Calls
Manipulation number configuration examples are provided for inbound and outbound calls in
Section 4.10.4.
¾ To configure the Number Manipulation tables:
1. Open the Number Manipulation page you want to configure (Configuration tab > Protocol
Configuration menu > Manipulation Tables submenu > Dest Number IP->Tel, Dest
Number Tel->IP, Source Number IP->Tel, or Source Number Tel->IP); the relevant
Manipulation table page is displayed (e.g., 'Source Phone Number Manipulation Table for
TelÆIP Calls' page).
Figure 4-34: Source Phone Number Manipulation Table for Tel-to-IP Calls
The figure above shows an example of the use of manipulation rules in the 'Source
Phone Number Manipulation Table for TelÆIP Calls':
• When the destination number is 035000 and source number is 20155, the source
number is changed to 97120155.
• When the source number is 1001876, it is changed to 587623.
• When the source number is 1234510012001, it is changed to 20018.
• When the source number is 3122, it is changed to 2312.
2. From the 'Table Index' drop-down list, select the range of entries that you want to edit (up to
20 entries can be configured for Source Number IP-to-Tel Manipulation, up to 120 entries
can be configured for Source Number Tel-to-IP Manipulation, and up to 100 entries for
Destination Number Manipulation).
