Dial Plan

A dial plan object is required for dial-in conferencing to normalize numbers entered by users. The normalization rules are used with conferencing to convert extensions entered by users to E.164-formatted numbers that are then matched to a user account. This enables users to enter only their extension instead of full phone number when dialing in to a conference from a phone.

To create a new dial plan to be assigned to dial-in conferencing users, perform the following steps:

1. Open the Lync Server 2010 Control Panel.

2. Click Voice Routing.

3. Click Dial Plan.

4. A dial plan can be scoped to apply at the site level, to a specific pool, or even just to a specific set of users. Click New and then select either Site dial plan, Pool dial plan or User dial plan.

5. Enter a Simple name for the dial plan to uniquely identify it within the topology.

6. Enter a Description for the dial plan.

7. If the dial plan is associated with a Dial-in Conferencing Region, enter the name of that region.

8. If users need to use any kind of prefix to dial external numbers, enter these digits in the External access prefix field.
