Question

A company was looking at the IT charges and saw many long-distance and international calls primarily to sites in North America and around the world. The administrator wants to optimize the PSTN expense. Which dial plan configuration reduces PSTN connectivity charges by using the IP network to bring the egress point to the PSTN as close as possible to the called number?

Options

Atranslation patterns
Btail end hop off
Cclient matter codes
Ddial rules

Explanation

Tail End Hop Off (TEHO) is a dial plan design strategy where calls are routed over the corporate IP WAN to a PSTN gateway that is geographically nearest to the called destination, rather than exiting the PSTN at the caller's local gateway. This minimizes or eliminates long-distance and international PSTN charges because the call only traverses local PSTN trunks at the far end. Option A (translation patterns) manipulates dialed digits but does not inherently reduce costs. Option C (client matter codes) tracks call costs by client/project for billing but does not optimize routing. Option D (dial rules) applies transformations on IP phones but is not a cost-optimization routing strategy.
