asterisk users - Jan 2007 - TDM404B VS TDM2401B

Hi List,
any good comparison between TDM404B and TDM2401B .
i'm not very happy with TDM404B voice quality, low volume and sometimes
echo.
I was wondering if any of you guys have good experience with TDM2401B.
thanks!

Same result, more FXO interfaces.

Hi

Check the gain set in the zap config file.  You can increase the in/out 
gain quite a bit over standard.

Echo is frequently a symptom of wrong country settings, hence wrong 
impedence settings.  Also endpoints matter
