3.3.2.3Defining Voice Coders

The gateway communicates with Mediation Server using either the G.711 A-law or G.711 µ-law coder. You can change the default coder using the gateway's Embedded Web Server.

¾To define the coder, take these 3 steps:

1.Open the ‘Coders' screen (Protocol Management menu > Protocol Definition > Coders).

Figure 3-11: Coders Screen

2.From the 'Coder Name' drop-down list, select the required coder.

3.Reset the gateway by clicking the Maintenance button on the main menu bar. Select the 'BURN' option to burn the configuration to flash memory, and then click the Reset button.

3.3.2.4Translating Numbers From / To E.164 Using Manipulation Tables for PBX/PSTN Connectivity

The Embedded Web Server's 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 Office Communications Server 2007 uses the standard E.164 format while your PBX or PSTN implements other number formats for dialing.

Due to Office Communications Server 2007normalization rules, the gateway may need to perform number manipulation for outbound calls (i.e., calls received from OCS client via Office Communications Server 2007) and inbound calls (i.e., calls destined for OCS client). If the gateway is connected to a PBX or directly to the PSTN, the 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 Office Communications Server 2007 E.164 format.

Manipulation number configuration examples are provided for inbound and outbound calls in Section 3.3.2.4.2 on page 26.
