[arm-allstar] Best Codecs for Portable Nodes

[Doug Crompton]

The other thing you need to be aware of is that as far as I know only
hamvoip code has the ilbc codec and even some hamvoip hubs and nodes may
not have it "turned on".  The best thing to do is have a fixed (home) node
that you connect to from your mobile hotspot node using ilbc. The fixed
node would then be connected to your ultimate destination(s) using any
available codec. This also allows others to connect to you on your hotspot
node via your fixed node as they probably could not directly connect.
