If you have an ASA, you can use it as a phone proxy, or use it to set up a phone VPN

If you have Jabber, you could implement Expressway so that you can register a softphone through to your CUCM on a public IP address, though this will not work for a physical endpoint (though I believe it's roadmapped).
