For something completely different, I have been making
phone calls where the path between two Asterisk PBXs is
GPRS. The GPRS channel is not symmetrical.
Just when I was wondering how to tweak things to fit
the bandwidth, I see that the Asterisk 1.2 version
has a handy codecs.conf file.
Even without special tweaking, I actually can listen
to voicemail from a GPRS connected laptop using speex.
The next interesting step is to see if I can get
IAX2 UDP packets between two ID-1 radios using
their ethernet interfaces....
