Nortel Networks NN43001-121 manual Normalizing using the Address Book Service

Normalizing phone numbers 193

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.
