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.

1. I was trying to record the session using ztmonitor, but it gives me

Writing combined stream to /tmp/zaptel.wav
Nothing to do with the stream(s) ...

when I execute ztmonitor 1 -f /tmp/zaptel.wav

Probably I'm using wrong tool? So I need your advice.

2. Probably, but not in near future.
