Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 96

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?

Answer options

• A. translation patterns
• B. tail end hop off
• C. client matter codes
• D. dial rules

Correct answer: B

Explanation

The correct answer, 'tail end hop off', effectively decreases PSTN costs by routing calls through the IP network to the closest exit point to the destination number. The other options, such as 'translation patterns', do not specifically target reducing PSTN charges, while 'client matter codes' and 'dial rules' focus on call management and billing rather than optimizing connectivity costs.
