+You can also easily stream music over the Internet/LAN for MOH with sox.  The ''ast-stream-mp3'' script directly supports MP3 streams or indirectly MP3 streams via a ''.pls'' playlist.
+Create file: ''/mnt/kd/bin/ast-stream-mp3''
+  #!/bin/sh
+  # Set VOLUME variable to linearly multiply the volume by a number.
+  # Value: "0.8" is 80%, "1.2" is 120%, default is "1.0" when not defined.
+  VOLUME="0.8"
+  URL="$1"
+  if [ "$URL" != "${URL%.pls}" ]; then
+    PLAYLIST="$(wget -q -O - $URL)"
+    if [ $? -ne 0 ]; then
+      sleep 10
+      exit 1
+    fi
+    URL="$(echo "$PLAYLIST" | sed -n -r -e 's/^File[0-9]*=(.*)$/\1/p' | head -n1)"
+    if [ -z "$URL" ]; then
+      sleep 10
+      exit 1
+    fi
+  fi
+  if [ -n "$VOLUME" ]; then
+    FOPTS="-v $VOLUME"
+  else
+    FOPTS=""
+  fi
+  wget -q -O - $URL | sox -t mp3 $FOPTS - -t raw -r 8000 -c 1 -
+Make the "''/mnt/kd/bin/ast-stream-mp3''" file executable:
+  chmod 755 /mnt/kd/bin/ast-stream-mp3
+Edit the Asterisk configuration file "''/etc/asterisk/musiconhold.conf''" and add this context:
-musiconhold.conf:
   [internet-stream]
   mode=custom
-  application=/mnt/kd/bin/stream-mp3.sh http://wnycfm.streamguys.com:80/
+  application=/mnt/kd/bin/ast-stream-mp3 http://wnycfm.streamguys.com:80/
-/mnt/kd/bin/stream-mp3.sh:
+!!Note ->!! The example MP3 source URL shown above is only an example, and does not imply it is legal to use for MOH in your country.  Choose a MP3 source URL carefully.
-  #!/bin/bash
-  wget -q -O - ${1} | sox -t mp3 - -t raw -r 8000 -c 1 -
+Reload the Asterisk MoH module:
+  asterisk -rx "module unload res_musiconhold.so"
+  asterisk -rx "module load res_musiconhold.so"
+!!Tip ->!! Never edit the ''ast-stream-mp3'' script without first unload'ing res_musiconhold.so .
