Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 195

The same digits sent in OOB, as well as in-band on the Cisco Unified Border Element, are being interpreted as duplicate digits by the receiving end. Which configuration must an engineer implement to resolve this issue?

Answer options

• A. DTMF Relay SIP-KPML
• B. DTMF Relay SIP-Notify
• C. DTMF Relay RTP-nte
• D. DTMF Relay Digit-Drop

Correct answer: C

Explanation

The correct answer is C, DTMF Relay RTP-nte, as it is specifically designed to handle DTMF tones over RTP, preventing duplication issues. Options A and B refer to SIP-based DTMF relay methods that may not address the OOB and in-band conflict, while option D, DTMF Relay Digit-Drop, does not provide a solution for duplicate digit interpretation.
