I mentioned this some days ago in this list. Echo suppression/cancelation. First of all it's a question of some rubber parts. Improve housing! But these won't do the job completely. I think, a 400MHz CPU plus Wolfson chip can do the magic (well, diminished responsiveness while canceling echo. So what? We're in a call). ZyXEL 9600 were able to cope with (transatlantic) echo. Though I had no close look at it yet. > According to my sources this function is normally built into the GSM > chipset. So we should check that when we shop for different ones. Maybe. There's few info on this. (someone send me the Siemens specs? Please!) /j
