[Asterisk-Users] DTMF Detection and noise in TDM10B

[Sergio Serrano Revuelto]

HI all,
	we get a TDM10B to probe it. I find two problems:
	
	-First, I hear a lot of noise in communication. I have tried do
"dd if=/dev/zero of=/dev/null &" but it isn't work.
	-Second, When I pickup phone connected to TDM10B I hear a
strange dial tone and * doesn't detect DTMF.

Any idea?

Thanks in advance,
srsergio
