asterisk users - Feb 2006 - DTMF Sporadicaly Being Generated

I just wanted to see if any one else has seen this or could help point me in
the right direction on this problem. 

I have a TE411P card in my * box. I am running FC4 x86_64. I used to have
two TE110 cards in the same box that worked without any problems. Since
changing to the TE411P cards, I am getting random DTMF tones being produced
on a bridged connection through the same Channel Bank that I was using
before upgrading to the TE411P. 

Port 1 -> PRI 1 
Port 2 -> PRI 2 
Port 3 -> Channel Bank 
Port 4 -> Empty 

The channel bank then connects to our recording computer through a 66 block.
So, our recording computer is picking up these tones on the recordings and
sometimes the DTMF tone is # sign which triggers our system to stop the
recording and produce a number (this is by design). We need to stop the
generation of these random DTMF tones so that our recordings do not end
prematurely.

Does anyone have any ideas where the DTMF tones are coming from? Are there
any know problems when there is a cell phone involved? 

Thank you, 
Michael Young

This is a known problem, been discussed on the lists many times. You 
should contact Digium Support, since you just purchased a Digium card. 
They are best equipped to handle issues related to Digium hardware.

To quote Kevin:

DTMF handling in the trunk is in a state of flux right now. It won't be 
resolved until this weekend.

Don't use SVN for a production system, it's lots broken right now. If
you really must, stick with r8786 for a while.
