Spesifically, see subjects "Voice over GPRS?" and "Encrypting
voice communications" in the February archive page at
http://lists.openmoko.org/pipermail/community/2007-February/thread.html

Summary: Possible to code support for this using GSM data calls (not GSM
voice calls due to GSM chip restrictions), which come with the quality
of service GPRS lacks. May cost a bit extra depending on your provider.
Compatibility with cryptophone.de probably possible, since their
protocol seems to be up for reimplementation. Either way, at least
Moko-to-Moko encrypted calls are quite possible to implement, just that
somebody (TM) needs to do the work.
