Summary:                    DTMF is not working correctly for cell phones.
Description: 
We have an issue calling the extension number from cell phones. Sometime is
works, but mostly fails.

The problem is that DTMF tones are coming as doubles or just in wrong
order. I'll attach asterisk console output for cell phones and land one
(yes, land phones works as expected - always).

Any help is really appreciated as most of our customers are mobile.

The question is when the distortion occurs? GSM->Telco -> zaptel ->
chan_dahdi.so. If I got things right, they are all the subject. Since the
records were made using Monitor() extension command, this involves all
chain, right?

I'm trying to debug the issue with Telco to see what they are getting.
I'll post a result as soon as I have it.
