What is digit analysis in CUCM?

• A. The process of recording digits for billing.
• B. The process of collecting digits and comparing them to patterns for routing.
• C. The process of encoding digits for voice codecs.
• D. The process of ignoring digits and routing by default.

Answer: (B)

Digit analysis in CUCM is the mechanism that collects the digits dialed by a user and compares them against the dial-plan patterns to decide where to route the call. As digits are entered, CUCM uses defined patterns (route patterns, translation patterns, etc.) and stop digits to determine the best match, then routes the call accordingly. This enables flexible handling of variable-length numbers, prefixes, and different dialing plans. It’s not about billing digits, encoding digits for codecs, or ignoring digits; it’s about turning the dialed digits into a routing decision by matching them to predefined patterns.
