Creating Dial-In Access Numbers

Dial-in access numbers are the phone numbers users dial to reach the audio conferencing service. For each access number, a SIP-enabled contact object is created within Active Directory.

Each dial-in access number has a dial-in conferencing region associated that ties it to a particular dial plan. The following options are available when you are creating a dial-in access number:

• Display Number—The text format of the number as it is displayed to users in the Online Meeting invitation.

• Display Name—The name of the Active Directory contact created for the access number.

• Line URI—The phone number assigned to the dial-in access contact. This should be specified in E.164 format with the “tel:” prefix.

• SIP URI—The SIP URI assigned to the contact object. It must be unique within the organization and use a “sip:” prefix.

• Pool—The pool where the contact object is homed.

• Primary Language—The primary language used to make conferencing announcements.

• Secondary Languages—Any secondary language choices for conferencing announcements. Up to four secondary languages can be specified.

• Associated Regions—Dial plan regions that are associated with the dial-in access number. Multiple regions can be associated to a single number, or a region can be associated to multiple dial-in access numbers.
