Do a siptrace on the calls with sngrep and see what codecs they are using.

Once you have recorded the audio convert it it the correct WAV format using this website:

The settings you want are:
Bit Resolution - 16 BIT
Sampling Rate - 8,000 Hz
Audio Channels - Mono

This should do the trick,

If it doesn't then also try and disable all codecs in FusionPBX with the exceptionof PCMU and PCMA
