tel:+14255551212;ext=5551212;ad-rdn=telephoneNumber;display-
Name=(425)555-1212
The ad-rdn = telephoneNumber is a proprietary parameter describes
the type of the phone number and displayName, which is a proprietary
parameter that holds the display format of this phone number (by default,
the original phone number before normalization).
By default, the msRTCSIP-RCC Line is copied from the proxy address
(attribute ad-rdn=telephoneNumber). The phone number is copied without
ad-rdn and display name parameters.
For example:
tel:+14257771234;ext=1234;ad-rdn=telephoneNumber;display-
name="(425) 7771234 * 1234"
is shown as:
tel:+14257771234;ext=1234
Normalizing using the Address Book Service
The Run time: Address Book service normalizes the original phone numbers
in Active Directory. In this case, the normalized phone numbers are not
stored in Active Directory and the output cannot be analyzed before it is
used by Office Communicator. Having Address Book Service properly setup
for an OC client is essential in receiving correct CLID info on call pop-ups.
Creating Normalization rules
Matching incoming calling numbers to the phone numbers for a Office
Communications Server user, and transforming free-form dialstrings to URIs
that can be called through TR/87, is performed by Office Communications
Server 2007 and Office Communicator 2007 through a process called
Normalization.
Normalization rules, according to Microsoft guidelines, must be defined to
make use of the integration of Office Communicator 2007 Remote Call
Control and Office Communications Server 2007 Multimedia functionality.
Each Office Communications Server user that uses Office Communicator
Remote Call Control capability must have appropriate Office
Communications configuration (in addition to the per-TN configuration
discussed previously).
You must consider and define SIP routing for TR/87 sessions for each Office
Communications Server user.
