Add an Extension Number to a UM Auto Attendant

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

Topic Last Modified: 2012-07-23

You can configure an extension number or multiple extension numbers on a Unified Messaging (UM) auto attendant in Microsoft Exchange Server 2010. When you add an extension number to a UM auto attendant, that number can be used by callers to access the auto attendant. Also, you may have to add extension numbers because there is more than one extension number that callers can use to access an auto attendant. By default, no extension numbers are configured when you create an auto attendant.

Note:
An extension number for a UM auto attendant is also known as a pilot identifier or pilot number.

You can create a new auto attendant without setting up an extension number for the auto attendant. You can also associate more than one telephone or extension number with a single auto attendant. You can either add the extension numbers when you create the UM auto attendant or add them after you configure the auto attendant. The number of digits in the extension number you configured on the UM auto attendant must match the number of digits for an extension number that's configured on the UM dial plan associated with the UM auto attendant.

Note:
You can also add a Session Initiation Protocol (SIP) address instead of adding an extension number. A SIP address is used by some IP Private Branch eXchanges (PBXs).
