I had echo with sjphone, upgraded to x-pro (www.xten.com) today, its $30 but it seems to have eliminated the echo entirely and made my ipaq usable.
That may help your problem, although its not free.. sjphone did not seem to have any more options to tweak, asterisk didnt either, so my last choice was to buy software. Sorry if that is the only option for you, but it appears to be that sjphone doesnt have any echo cancelation and on some devices (like my ipaq) the audio in/out is so closely coupled that echo is unavoidable, on any non headset device it also appears to be.
