asterisk users - Dec 2009 - Random DTMF tones generated from speech in conversations

Hi,

My Asterisk systems runs like a dream with mISDN, SIP and even and old
Digium board. But have almost in every conversation some irritating DTMF
being generated. The seems to be just as often from all trunks but are
worse if noise load speaker in other end.

Any good advices?

Where to look for forgotten DTMF detection settings?

Thank you!

HB

I used to have this problem with a Digium 400p -- even when not in use
and a Motherboard which was inadequate in terms of the interrupts for
the Digium card -- when I got a better Motherboard the problem went
away.

Your life is like a penny.  You're going to lose it.  The question is:
How do
you spend it?

I have seen this years ago, i received complaints about women voices 
triggering dtmf.
With some help from Mr. Underwood, it was able to confirm lots of false 
positives on the dtmf detection.

My issues went away when we upgraded all cards to the ones with the 
octasic DSP chip on them.
