Security and Tunneling

Can one create some kind of tunnel for voice channels so no one can sniff the packets? The only security that's offered is the H.235 (H.Secure) that encrypts the RAS (Registration, Admission and Status) packets using MD5 encryption algorithm. There's no material about VoIP tunneling and/or running VoIP calls via VPN. Encrypting voice channels doesn't make any sence to me, being that it will introduce additional delay. Does anyone have an answer for this problem?

Sure you can encrypt voice traffic (and prioritize it accordingly with QoS) over an IPSec tunnel. No problem

Shannon, I am trying to get one of our customers to work with encrypting voice the QOS is already setup on the routers and everytime I turn on crypto map, no one dial in from the outside, but local numbers work fine. Please advise.
