Depends what sort of calls you mean. If it's GSM voice calls then the same problems apply as already discussed. If you're talking about a data link encrypted end to end and passing voice data then it's possible, probably using established standards. You could make an OpenVPN or IPsec tunnel end to end, then use SIP, h323 or IAX2 over it. You could use one of the secured versions of SIP directly, at least one of which uses public keys, but none of them are universally accepted. You could even roll your own protocol using TLS or something. _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
