Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 429

An engineer must configure DTMF relay on a Cisco Unified Border Element by using RFC2833 as the preferred relay mechanism and KPML as the next preferred relay mechanism. The engineer logs in to the CUBE and enters the dial-peer configuration level. Which command should be run at the dial-peer configuration level?

Answer options

Correct answer: D

Explanation

The correct command, 'dtmf-relay rtp-nte sip-kpml', specifies the primary DTMF relay method as RFC2833 (rtp-nte) and the secondary as KPML. The other options either misplace the preferred methods or include incorrect combinations that do not align with the specified preference.
