On my TDM410P pci-card I have an hardware echo cancellation module (Digium VPMADT032 EC Modul). I have set 'echocancel=yes' in my chan_dahdi.conf to activate this hardware module.
Do I now have 2 echo cancellers that are activated ? A software echo canceller and a hardware echo canceller ?? Form the documentation on DAHDI : ; Note that if any of your DAHDI cards have hardware echo cancellers, ; then this setting only turns them on and off; ; echocancel=yes ; That's al I have for echo cancellation... I thought the hardware module of Digium was of great quality ?! > > I have seen this happen with the aggressive echo cancel algorithms.
