There has to be a way (=button, =LCM) to end the call at least ;-) Sure it's not nice to have CPU running full power for some task that can be done in GSM chipset (though i'm not sure this is a common feature for these chips. Maybe we really need a specialized chip for this), but switching off display is sth that can be done only while you really have the phone pressed to your ear - there are all kinds of user interaction (e.g. Hold, Mute/Volume, DTMF) and usefull info (e.g. duration, BattState) during established call, that need a working LCM. We have no keyboard! Just TS. You're not suggesting an interface-free phone you have to shake or sth to end the call? However, to throttle down the CPU while call sure is a good thing, that's worth looking for different ways to cancel echo. cheers jOERG
