Number formats supported by Office Communicator

Dialstrings and E.164 International number format are the two types of numbers used by Office Communicator. Both number formats apply to computer and phone calls with Office Communicator.

Dialstrings

By default, digits dialed from Office Communicator that are not fully qualified are sent as dialstrings. The sequence of digits entered in Office Communicator are sent directly to the Call Server to be dialed. This allows a user to dial all numbers that you would typically expect to dial from a phone local to the CS 1000. Normalization rules should be defined in the Location Profile to convert the dialstrings to the E.164 International format for all types of PSTN calls. For example, NXX, NPA and International.

E.164 International Format Numbers

The recommended format of numbers stored in Microsoft applications is the E.164 International number format. This is a variable length number that consists of a plus sign (+) followed by a 1 to 3 digit country code and a national number 15-n digits long—where n is the length of the country code.
