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.

I will run these files through Asterisk DSP code to see what asterisk
thinks.
However as you left landline tones in the raw file - I bet you can hear
the huge difference yourself. Just compare the last set of three DTMF tones
from the raw file (landline) with the previous (cell). Compared to the
cell, landline signal is just perfect.
