Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 449

An engineer configures Cisco UCM to use a second PSTN provider and ensures that the called party information that is sent matches what the provider expects. However, the engineer already configured the gateway, created the route group, and added the route group to the existing route list. Which action ensures the called party information requirement without affecting the existing PSTN provider?

Answer options

• A. Add a called party transform mask to the route list detail for the new PSTN route group.
• B. Add a called party transform mask to the route pattern.
• C. Add an external phone number mask to all devices.
• D. Add a calling party transform mask to the route pattern.

Correct answer: A

Explanation

The correct answer is A because adding a called party transform mask to the route list detail for the new PSTN route group specifically targets the new provider's requirements without altering the existing configuration. Options B, C, and D do not achieve this goal as they either modify the route pattern or affect all devices, which could disrupt the settings for the current PSTN provider.
