Configure Access Numbers for Dial-in Conferencing

Topic Last Modified: 2009-01-25

To provide support for dial-in conferencing for on-premises audio/video or Web conferences, Conferencing Attendant must be configured with access phone numbers.

Note

You cannot use a new access phone number for dial-in conferencing until Active Directory replication of that phone number is complete.

Configure access phone numbers

  1. Log on to the Office Communications Server where you want to run the Conferencing Attendant application as a member of the Administrators group, the Domain Admins group, and the RTCUniversalServerAdmins group.

  2. Click Start, point to All Programs, point to Administrative Tools, and then click Office Communications Server 2007 R2.

  3. In the console tree, right-click the forest node.

  4. Click Properties, and then click Conferencing Attendant Properties.

  5. On the Access Phone Numbers tab, click Add.

  6. On the Add Conferencing Attendant Number dialog box, specify the following:

    • In Display number, type the conference call phone number that public switched telephone network (PSTN) phone users can dial to join a conference. (This number is displayed in meeting invitations and on the Dial-in Conferencing Web page.)

    • In Display name, type a clear, meaningful description for the conference call phone number. This is the name that will be associated with the conference call phone number in Office Communicator search results.

    • In Line URI, type the E.164 number of the conference call phone number in TEL URI format, including the + symbol before the number and excluding spaces. For example, +14255550200.

    • Optionally, in SIP URI, click the text box, type a unique SIP URI for this Conferencing Attendant access phone number. This SIP URI will be displayed in various locations including, but not limited to, call notification messages and in previous versions of Communicator clients.

      Note

      The same SIP URI cannot be reused by another Conferencing Attendant access phone number.
      If you prefer, you can use the automatically generated SIP URI.

    • In SIP URI, in the drop-down list box, click the domain of the Conferencing Attendant application that will support this conference call phone number.

  7. Optionally, to use an existing contact object instead of creating a new Active Directory Domain Services contact object for the specified conference call phone number, click Advanced.

    Important

    If you want to use an existing contact object, you must have Read/write permissions to the OU that contains the contact object. To specify this advanced setting, you must delegate permissions to the RTCUniversalServerAdmins group.

  8. If necessary, delegate permissions to the RTCUniversalServerAdmins group by running the following command: Lcscmd.exe /domain /action:CreateLcsOUPermissions /OU:OU=<DN of the OU where the contact object resides> /ObjectType:AppContact where OU is the DN of the organizational unit containing the contact object to which you are granting administrative permissions, excluding the domain root portion of the DN. Otherwise, skip to the next step.

  9. In the Advanced Configuration dialog box, select the Specify an Active Directory Contact object check box, type the DN of the contact object you want to use, and then click OK.

  10. Under Serviced by pool, in the drop-down list box, click the pool that is running the instance of Conferencing Attendant that will support this conference call phone number.

  11. Under Language Settings, click the Primary language drop-down list box, and then click the language in which prompts will be played for this conference call phone number. (Supported languages are displayed alongside each access phone number in meeting invitations and on the Dial-in Conferencing Web page.)

  12. Optionally, to provide users with additional language options for this conference call phone number, click Add.

  13. In the Select Language dialog box, click the Available languages drop-down list box, click an additional language that you want to support for callers to this conference call phone number, and then click OK. (You can select up to four secondary languages for each access phone number.)

  14. When you are finished, click OK.
