Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 219

An administrator is configuring a new Cisco UCM with PSTN capabilities. Due to bandwidth constraints, audio compression is used on the codec. DTMF must work as expected because the customer is calling many call centers where the users must select options in the call. Where is DTMF out-of-band in a CCM 12.5 with SIP-based gateway configured?

Answer options

• A. in the DTMF setting under SIP profile on the Cisco Unified Border Element
• B. in DTMF settings in the audio codec preference list under regions in the Cisco UCM
• C. in regions on the Cisco UCM where you set the appropriate codec to use
• D. in the dial peer on the Cisco IOS router

Correct answer: D

Explanation

The correct answer is D because DTMF out-of-band signaling is typically configured within the dial peer settings on the Cisco IOS router to ensure proper transmission during calls. The other options do not address the specific configuration location for DTMF signaling in this context, as they pertain to SIP profiles or codec preferences that do not directly manage DTMF signaling in the same way.
