Polycom CMA System Operations Guide

Determining Area Codes

It is recommended you enter area codes for:

•The area in which the site is located.

•The area surrounding the site.

•Frequently called numbers.

You should also include special rate plans for intrastate calling.

Determining Country Codes

If you make international calls and you determine that calls to a certain country are less expensive from a particular gateway, enter the dial string for this country in the LCR table for the selected gateway.

Determining the Weighted Cost

When you enter call strings in an LCR table, associate a weighted cost with each one. You can base the cost on a monetary value or ratio that compares costs between several locations. The weighted cost determines which call string is most cost-effective to use.

You can calculate costs for the following types of calls:

•Local

•Local toll

•Intrastate

•Interstate

•International long distance
