Benny, The following code in the function pjmedia_silence_det_set_params(...) gave a divide by zero error: sd->min_signal_cnt = min_signal / sd->ptime; sd->min_silence_cnt = min_silence / sd->ptime; sd->recalc_cnt = recalc_time / sd->ptime; I was experiencing other errors, but this code should be protected against error conditions and should check the value of sd->ptime for zero before performing the division operation.
