Use IAX and the ILBC codec.
You could also try IAX trunking to bundle multiple channels into a
single IAX stream, but in my experience this requires a fairly good
low latency connection, so it's probably a no go in your particular
case. Also, if you have jitter and want to use the jitter buffer, IAX
trunking is a no go.
Still, even without IAX trunking, IAX and ILBC with a QoS of
lowbandwidth between the two IAX hosts at each end of the satellite
connection should do fine.
