Com - The Power of Knowing 642-432 QUESTION 84 What are two characteristics of a distributed call processing model? ) A. sites connected via the PSTN B. sites connected via the IP WAN C. call processing agent at one site D. call processing agent at each site Answer: B, D QUESTION 85 You have all ten digits being sent to your CM from the PSTN (via a gateway). If you have four digit extensions, how do you make sure that the call gets routed? A. update the Phone Calling Parity mask B. -change the Route Group configuration C.
You are deploying an IP telephony solution using MGCP. The call agent expects the gateway to use UDP port 2427 but an application on the Certkiller network is already using that port. You want to use port 4662 instead. Which command would allow you to change the UDP port that the call agents and gateway communicate on? A. Router(config)# mgcp UDP 4662 B. Router(config)# mgcp gateway 4662 C. Router(config)# mgcp call-agent 4662 D. Router(config-dial-peer)#application MGCPAPP 4662 E. com. Numerous Certkiller users complain that they are unable to complete calls through the MGCP network.
The Certkiller network uses RTCP. Your newly appointed Certkiller trainee wants to know what RTCP does. What will your reply be? A. It provides independent services irrespective of RTP. B. It provides compression techniques to save bandwidth. C. It provides in-band control information for an RTP flow. D. It provides out-of-band control information for an RTP flow. Answer: D Explanation: RTCP provides out-of-band control information for an RTP flow. QUESTION 160 Which statement is true about the MGCP call agent?
