Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 70

Which DTMF relay method configured on a SIP dial-peer will ensure that a media resource is not invoked by Unified CM for calls to UCCX IVRs?

Answer options

• A. sdtmf-relay h245-signal
• B. dtmf-relay rtp-nte
• C. dtmf-relay sip-notify
• D. dtmf-relay sip-kpml

Correct answer: D

Explanation

The correct answer is D, as 'dtmf-relay sip-kpml' ensures that the call signaling information is sent without invoking media resources. Options A, B, and C either do not prevent media resource invocation or use different signaling methods that may not align with the requirements for UCCX IVRs.
