Dears,

The above link I have been before and it was only mentioning SRTP package for MGCP gateways which is not possible in my environment becz the CUCM in not in mixed mode Please confirm to me m I correct ???

For VPN connection perspective between CUCM and MGCP Gateway I think we can do which will encrypt the signals also the payload,

Apart from the above I don't see anything related to security for MGCP gateways.

Please confirm experts.
