[Asterisk-Users] Damn DTMF Beeps on my calls

[Jeremiah Chapman]

Well, it sounds to me like his phone actually "IS" sending you keypresses.
You stated that it goes silent on his end while you are hearing his DTMF
tones. Sounds like the phone is silencing his end, as it would if he were
intentionally dialing out. I am guessing that he has a bad phone or
something on his end is causing the issue.

Sincerely,

Texas Web Geek

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.
