500-443 Question #18: Real Exam Question with Answer & Explanation

The correct answer is C. CTI ports use out of band DTMF, and SIP trunks use RFC2833 in-band DTMF. D. MTP resource is required to convert mobile agent out of band and CVP in-band signaling.. One of the requirements for MTP configuration in Mobile Agent is that CTI ports use out of band DTMF, and SIP trunks use RFC2833 in-band DTMF, as this allows CVP to receive and process DTMF signals from different sources. Another requirement for MTP configuration in Mobile Agent

Question

Options

AHardware-based MTPs in Cisco IOS gateway is cost-efficient than software-based MTPS in Cisco
BSynchronization between servers and clients is needed.
CCTI ports use out of band DTMF, and SIP trunks use RFC2833 in-band DTMF.
DMTP resource is required to convert mobile agent out of band and CVP in-band signaling.
ESoftware-based MTPs using the Cisco IP Voice Media Streaming Application is supported.

Explanation

One of the requirements for MTP configuration in Mobile Agent is that CTI ports use out of band DTMF, and SIP trunks use RFC2833 in-band DTMF, as this allows CVP to receive and process DTMF signals from different sources. Another requirement for MTP configuration in Mobile Agent is that MTP resource is required to convert mobile agent out of band and CVP in-band signaling, as this enables CVP to communicate with mobile agent phones using different protocols.
