Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 157

Due to a shortage of physical interfaces on a device, the administrator requires that a loopback for RTP is used. Which command is required when using a loopback interface for RTP?

Answer options

• A. voice-class sip early-offer forced
• B. voice-class sip bind control source-interface Loopback0
• C. voice-class sip bind media source-interface Loopback0
• D. voice-class sip resource priority mode passthrough

Correct answer: C

Explanation

The correct command, 'voice-class sip bind media source-interface Loopback0', specifically directs RTP traffic to use the Loopback0 interface. The other options do not relate to binding media traffic to the loopback interface and serve different purposes, making them unsuitable for this requirement.
