Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 77

A customer is deploying a SIP IOS gateway for a customer who requires that in-band DTMF relay is first priority and out-of-band DTMF relay is second priority.
Which IOS entry sets the required priority?

Answer options

Correct answer: A

Explanation

The correct answer, A, specifies the priority for in-band DTMF relay (rtp-nte) first, followed by out-of-band relay (sip-notify). Option B only sets the out-of-band relay, while C and D do not correctly establish the required priority for in-band and out-of-band DTMF relay.
