You are the network engineer at domain.com.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 TestKing 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)#mgcpUDP 4662

B.
Router(config)#mgcpgateway 4662

C.
Router(config)#mgcpcall-agent 4662

D.
Router(config-dial-peer)#application MGCPAPP 4662

E.
Router(config)#mgcpdefault-package gm-package 4662
