Summary:                    Wideband Streaming Music-On-Hold (slin16)
Description: 
I'm using this to stream MOH from a local icecast service.

musiconhold.conf:
[default8]
mode=custom
application=/usr/bin/icestream.sh
format=slin

icestream.sh:
#!/bin/sh
/usr/bin/mpg123 -q -s http://localhost:8000/station.mp3 | sox -t raw -s -r
44100 -4 - -s -r 8000 -2 -c 1 -t raw -

It works great, but now that I have wideband capable phones I would like
to stream the MOH in wideband. I tried setting that up:

musiconhold.conf:
[default16]
mode=custom
application=/usr/bin/icestream16.sh
format=slin16

icestream16.sh:
#!/bin/sh
/usr/bin/mpg123 -q -s http://localhost:8000/station.mp3 | sox -t raw -s -r
44100 -4 - -s -r 16000 -2 -c 1 -t raw -

"sox": -s is signed, -2 is 16 bits, -c 1 is mono, -r 16000 is 16khz
This is what I assume is the "slin16" format specification.

Using the "default16" music-on-hold, I get stuttered audio (sound on/off
10 or so times per second).
