Excellent!
But ... this brings up a new question. Where do your bandwidth numbers
come from for the chart on page 6? Is that the total bandwidth in *both*
directions? The numbers are about a double of the 17kbps I calculate for
EchoLink.
{ (8000 samples/second) / (160 samples/gsm frame) / (4 gsm
frames/packet) = 12.5 packets/second. or 1 packet every .08 seconds.
Each packet consists of an IP header and an UDP header so
(12.5 packets/second) * (20+8+12+(33 * 4)) bytes/packet) * 8 bits/byte =
17200 bits/second.}
