What is a translation profile?

• A. A device that plays hold music.
• B. A policy for QoS on voice traffic.
• C. A set of translation rules applied to called/calling numbers.
• D. A script for dial plan normalization.

Answer: (C)

A translation profile is a collection of digit transformation rules that are applied to called and calling numbers to fit the dial plan and routing needs. It lets the gateway rewrite numbers as they leave or arrive, so local numbers can be mapped to proper international or trunk formats, or prefixes can be added or removed automatically. You define rules that match digit patterns and specify how they should be replaced, then attach the profile to a voice port or dial-peer so the device applies the changes automatically during call setup. This is all about normalizing and routing numbers, not playing hold music and not about QoS policies. It’s also not a general script for dial-plan normalization, but a defined set of rules that handles the number transformations required for proper call routing.
