194Configuration

MCM provides authorization of Remote Call Control service requests based on the configuration defined in Active Directory for each Office Communications Server user.

Office Communicator requires that all phone numbers be in the standardized TEL URI format (RFC 3966) for reverse number lookup (matching the phone number of an incoming call to a known Office Communications Server user) and for dialing (either through an adhoc interface or through a menu from a user object).

Matching an incoming phone number to a Office Communications Server user identity is used to establish multimedia sessions. If the Office Communications Server user identity cannot be determined from a phone number, then Office Communications Server multimedia sessions cannot be established with the calling or called party.

Example

A Office Communications Server user accesses an Active Directory phone number for Jim (in Outlook, for example) to make a Remote Call Control phone call. Office Communicator uses normalization to map the free-form phone number to a TEL URI prior to sending the TR/87 Make Call service request. You can assume the following points for normalizing phone numbers:

•The normalization method chosen is Address Book Service – Run time as opposed to using the offline method

•An Active Directory entry exists for Jim with business phone number ESN 343-2356

•A normalization rule exists that defines a regular expression (as defined in Figure 71 "Normalization rule example for UDP dial plan" (page 195)) to map ESN 343-2356 to +16239675000;ext=3432356.
