Also, be aware, by default only G729 codec is registered when loading
mod_sangoma_codec. If you want other codecs you must enable them in

<param name="register" value="all"/>

Something like that would register all supported codecs by the card. As
stated by Steve you should not load conflicting modules, for example loading
mod_voipcodecs and registering G722 codec in sangoma_codec.conf.xml would
cause a conflict.
