Specifying Parameters for the Routing Decision
1. Open the Network Call Routing page on the Trunk Group edit page, shown in Figure 23.

2. Enter values into the Local Area Code, Additional Local Area Codes, and Nearby Area Codes
fields.
3. Open the Trunk Group edit page and, toward the bottom of the page, click Go to Local prefixes.
The Local Prefixes dialog box appears. It allows you to enter prefix exceptions against a local area
code. The Network Call Routing algorithm handles prefix exceptions for the local area code as
long distance, which minimizes toll charges.
Refer to the ShoreTel System Administration Guide for more information about the Trunk Group
edit page and the Local Prefixes dialog box.
The area codes on the Site edit page have no impact on call routing decisions.
