Dial-in users enter their phone number or extension and a PIN to join conferences as authenticated users. The telephony Line URI specified on Communications Server user accounts is required for authentication.
The procedure in this topic describes how to assign a Line URI for a single user account. If you need to assign a Line URI for multiple user accounts, you can create a script that uses the Set-CsUser cmdlet. To see a sample script that assigns Line URI to multiple user accounts, see "Assign Line URIs to Multiple Users" at http://go.microsoft.com/fwlink/?LinkId=196945.
To configure user account settings
Open Communications Server Control Panel.
In the left navigation bar, click Users.
In the search field, type the name of the user you want to configure for dial-in conferencing or click Add filter to specify search fields, and then click Find.
Note: For details about searching for users, see Search for Communications Server Users.
Double-click the user name to open the Edit user dialog box.
Under Telephony, in the Line URI field, type a unique, normalized phone number (for example, tel:+14255550200).
Note: You can specify Line URI only if Telephony is set to PC-to-PC only, Enterprise Voice, or Remote call control.
