Actually, the digital radio (cdma, gsm) data
interfaces are already encrypted. However, I am not
sure how strong of encryption it is, and I think it
only affects the radio network. So, you would have to
check to see if the connection between the radio
network and the internet is encrypted. For mobile to
mobile calls that stay in the same radio network (i.e.
if the asterisk machine was within the provider's 
private network), you would be ok I believe.
