[Asterisk-Users] TDM04B + Voicemail poor Quality

[Nitesh Divecha]

Hello All,

Recently, I installed TDM04B 4 FXO card on to my Asterisk box and  
installation went perfect.

The only problem I am facing is the Voice mail has very poor quality  
when any users leave voice message via PSTN line.

We can not hear either from the extension nor from the WAV email  
attached.

Has anyone experienced this problem before, please help?

Thanks,
Neel
