That's what www.cryptophone.de does to avoid latency issues. Some networks
block mobile to mobile data calls though.

It doesnt need to cost a bit. In fact, this is why I am on this list and
why I'll be getting a Neo phone. We presented at CCC:
The video is available at: http://chameleon.cypherpunks.ca/

In essence, a phone using Openswan, Xl2tpd, openvpn, pjsua, Jabberclient talking to an
server running Openswan, Xl2tpd, openvpn, asterisk, jabber server.

We hope to have Neo firmware available before you can order the hardware :)

For more details, see our presentation.
