194 Configuration
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

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
