When your musiconhold.conf looks like that ...

---- cut -----
[general]

[default]
mode=files
directory=moh

[your_moh_class]
mode=files
directory=/your/path/to/your/moh/files
---- cut -----

... then you can put any supported file format into the specified
directory. GSM is only one option. Asterisk will take the best (meaning
"cheapest") file format availble in this directory.
