Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 51

How are E.164 called-party numbers normalized on a globalized call-routing environment in Cisco Unified Communications Manager?

Answer options

• A. Normalization is achieved by stripping or translating the called numbers to internally used directory numbers.
• B. Normalization is achieved by setting up calling search spaces and partitions at the SIP trunks for PSTN connection.
• C. Call ingress must be normalized before the call being routed.
• D. Normalization is not required.

Correct answer: A

Explanation

The correct answer, A, indicates that called-party numbers are adjusted to match the internal directory numbers, which is essential for proper call routing. Option B focuses on search spaces and partitions, which do not directly contribute to normalization. Option C mentions call ingress normalization but does not specify the process for E.164 numbers. Option D incorrectly states that normalization is not necessary, which is false in this context.
