I don't have an SPA-2000, nor am I any expert on these things, but it sounds like you are facing the traditional Asterisk + hybrid PSTN line echo issues. Chances are that any SIP device plugged into the local side of your asterisk box will start with a nice echo - which eliminates itself as echo training occurs.
Have a look at the wiki ( http://www.voip-info.org/tiki-index.php? page=Asterisk%20echo%20avoidance ) and at the list for the last few weeks and read some of the settings you can try to eliminate the echo.
Not sure if it helps... but good luck!
