Use this option to specify your system’s home area code. This is the area code in which the system is installed. You must make an assignment in this program so that Caller ID can properly process callbacks (return calls).
Options 3712-03: Home Area Code Exception List Type through 3715-[01-96]: Foreign Area Code Exception List Table Data determine how the system redials Caller ID calls received as 10 digits or less. This is the US standard (i.e., the leading 1 is not received from telco for long distance calls). If the system is in an area where the telco provides more than 10 digits, the digits are redialed as is (with no modification).
