[Asterisk-Users] Damn DTMF Beeps on my calls

[Me]

Well this happens a LOT when I call one particular person, not so much when 
I call others.

Both sides of the call are running Sipura ATA's with * in the middle, no 
termination or Zap in between at all.

It seems that when I call this person from my home address it occurs a LOT 
like 1 or 2 times a minute or more at times. When I call from another 
location, same ATA type but different building it doesn't happen (I don't 
think).

The other caller does not here it at all, he only hears silence when I hear 
the beep. It sounds EXACTLY like a key being pressed on my phone. It's not 
just a beep, to answer the other posters question.
