# Define a Line Group

1. From the Main menu, select (S) System maintenance, (R) Reconfiguration, (R) Reconfigure system, then (G) Offline Menu.

2. Select (B) Duplicate Active Configuration. The system copies the current (active) configuration. When copying is complete, the short form of the Offline menu appears.

Note: All subsequent steps in this procedure – along with any other configuration entries – affect only the inactive configuration, and will take effect only after you activate the inactive configuration.

3. From the NuPoint Voice Configuration Offline menu, select (G) Line Groups.

4. Select (G) Current Group to specify the line group number.

5. Enter the number of the line group (1-24) to be used for the application.

6. Select (N) Name of Current Group and enter a descriptive name of the application line group (for example, "Incoming").

7. Add the desired lines:
   Select (A) Add Lines to Current Group. Each line number is expressed as a triplet, where module, slot, and port number are separated by colons (:). If you have a one-module server, you can refer to just the slot and port number. If you have a multi-module server, you must specify the module number as well, or the server assumes you are configuring Module 1 only. See Module/Slot/Host table.

Note: Support for multiple-module servers (e.g. NPM UM 640) was discontinued with NuPoint Release 6.0.

All of these formats are valid:

Example | Specifies
1:* | All lines
1:0:0-1:0:59 | All lines from 0 to 59 on module 1
1:0:* | All lines on module 1
1:0:0-2:0:4 | All lines on module 1, slot 0, through module 2, slot 0, port 4
1:*,2:* | All lines on modules 1 and 2

8. To enable G.729 audio compression (G.711 is enabled by default), select (P) Enable G729, and then enter 1 [Yes].

9. Exit to the NuPoint Voice Configuration Offline Menu.

10. Select (A) Line Group Only applications. A list of available applications is displayed.

11. Select (G) Group Selected and then select the application to configure from the list.

Note: If this Line Group is going to be used for Call Director, select (V) NuPoint Voice and then select (U) User Interface and (C) Call Director.

12. When you have configured the new line group, exit to the main menu and select (A) Activate Configuration.

13. When the activation is complete, test the new line group.

Note: If G.729 audio compression is enabled for the NuPoint UM line group:

- If you enable G.729, you cannot select a Fax Group Connection for the line group.

- For a Mitel 5000 CP integration, access the Speech Encoding Setting field on the 5000 CP (located in System\Devices and Feature Codes\Node IP Connection Groups\<Pxxxx>IP Call Configuration or System\IP-Related Information\Call Configurations) and select G.729.

- For a MiVoice Business ICP integration, create a network zone on the MiVoice Business ICP, enable Intra-zone Compression, and then assign all endpoints, including sets and IP extensions mapped to NuPoint ports, to the zone. In addition, make sure to equip the MiVoice Business ICP with Digital Signal Processors (DSPs) that support G.729.

- For a Dialogic Media Gateway integration, access the DMG Web Interface, select the network group for this implementation (located under Configuration > VoIP > Network Groups), and then select Low Bit Rate Codec as Audio Codec #1.
