Hi we use Linphone and Speex AEC in Linux on an ARM platform. We have issues with long settling time at system start and if some sudden sound like hand claps etc occur during a call. This is a system with speakers in both ends. Are there any settings that we can use to optimise this? We have tried with shorten filter lengths (now we use 2048 @ 8 kHz sampling) so ~250 ms we have tried to cut this but then we don't get rid of all echo. Any ideas are welcome.
