If you're looking for encryption enough to foil casual sniffers why not just 
use something like DES1 or even straightforward and fast XOR encryption and 
use a hash of the call ID, trunking messages and rekey with new values 
every few seconds (let's say with a random sample of the unencrypted audio 
from the stream) -- the only hard part is verifying that both sides have 
that particular packet.
