Normalizing phone numbers

Office Communicator 2007 requires that all phone numbers be in standard
TEL URI format as defined in RFC 3966 for dialing and for reverse number
lookup.
Office Communicator 2007 uses phone numbers that are provisioned
(Active Directory and Outlook) and that are adhoc from the user through the
user interface. All sources can be free format—a convention that is not in
compliance with TEL URI.
The phone numbers configured for the Office Communicator user in the
Active Directory are normalized. The PBX private dialing plan phone
number is normalized to the Line URI format. For example, E.164;ext=CDP
number or UDP number, based on the dialing plan.
The following lists some examples of normalization:
•
•
•
Phone numbers are normalized in Active Directory. Each user can have
multiple phone numbers such as Office, Mobile, and Home. Two options are
available to normalize these numbers: Offline and Address Book Service.
See Microsoft Office Communications Server 2007 Planning Guide for more
information on normalization.
All normalization rules must be in Generic script.
Normalizing Offline (Recommended)
The user's phone number is read from the Active Directory user object,
original fields. These numbers are normalized offline to TEL URI format and
stored in Active Directory in a different field named proxy address (multi
value). Microsoft provides a reference on how to build a tool for this task.
If you use this option, then Address Book Service must not normalize the
phone numbers and must instead publish only normalized phone numbers
in the proxy address.
Each number in the proxy address is attached with an attribute that
describes the phone number (for example: Office, Home, and so on).

.
The number ESN 343-5555 would be normalized to
+16139620100;ext=3435555.
The number +1 (425) 7066340 would be normalized to +14257066340.
A number 1-800-368-3908 would be normalized to +18003683908.
