Implementing Cisco Collaboration Devices (CICD, legacy) — Question 43

A voice engineer is setting up a Cisco 2951 Integrated Services Router with Cisco Unified Communications Manager Express. To enable voice features for SIP endpoints, which command must the engineer enter?

Answer options

• A. telephony-service
• B. ip voice
• C. voice plan
• D. voice service voip

Correct answer: D

Explanation

The correct command is 'voice service voip', as it enables VoIP features necessary for SIP endpoints on a Cisco router. The other options do not specifically configure the necessary VoIP services for SIP, and thus are not applicable in this context.
