Country or region

You must specify the country or region in which the system is to be used by typing its international dialing code. For example, for the U.S. or Canada, type 1; for France, type 33.

There is no default value for country or region. Once you have made your choice, the telephony configuration wizard excludes choices of values for other items that are inappropriate for the country or region that you have selected.

Parameters that seriously affect the operation of the system are set according to the country or region selected; this might affect compliance with telecommunications authority regulations, and must only be done by authorized personnel familiar with these requirements.

The choice of country or region dictates whether the system is E1 or T1. In an E1 system, each trunk has 30 channels; in a T1 system, each trunk has 24 channels.
