Signalling between CUCM and gateways is protected through IPSEC  and RTP through sRTP. That is the easy part. for secure signalling between CUCM and phone you will need to put the cluster into mixed mode, for which you will need to purchase Cisco's etokens.

This is by far the most comprehensive document I have come across:
