Hi I have an MGCP gateway configured with MGCP as per the Media and Signaling Authentication and Encryption Feature on Cisco IOS MGCP Gateways Cisco Document. There is nothing in here to say how to configure the IPSec on the UCM version 6. Without the IPSec connection to the CM Cisco do not consider this as being secure. Is anybody able to help me to get this configured? I have the crypto config below and some debugs are attached. (keys have been ommitted for obvious reasons).
