I modified app.c to print out the totalsilence when recording the message in the voicemail and ... dspsilence=0 dspsilence=0 dspsilence=0 it always equals 0... maxsilence=8 silencethreshold=128 My line seems to be pretty silent... (and it also doesn't detect silence...) any hints? I'm having some problems.. Could it be because it's on the same IRQ as my ethernet adapter? Thank you very much for your help!
