Using mpg123

Using mpg123 for streaming you MOH i think its discouraged, you get the following problems while using it:

• you get this warning inside CallWeaver console/logs:

  Warning, flexible rate not heavily tested!

• you get this inside the logs:

  res_musiconhold.c:457 monitor_custom_command: Request to schedule in the past?

  again try not to use mpg123 for MoH.

just switch to madplay.

Using madplay

Install madplay and use this in musiconhold.conf:

[default]
mode=custom
directory=/var/spool/callweaver/moh
application=/usr/bin/madplay -Qzr -o raw:- --mono -R 8000 -a -12
format=slin

If you get this problem:

frame.c:1541 opbx_codec_get_len: Unable to calculate sample length for format unknown

probably its because you used “moh reload” during your migration from mpg123 to madplay. To fix this only chance is to issue a “restart” from the CLI.

This problem was not reproducible.
