Hi.
DTMF recognition could be device problem.
For example I have a setup which confirm that:
However I stuck and don't know in what direction to continue.
Have such schema:
Asterisk <-> sipura3000 <-> Land Line.
When call comes from cellphone spa3k captures DTMF and in debug from
spa3k I see
first digit doubled almost each time.

On cell phone typed 1010 during Asterisk IVR.
BTW, tried on different celphones from different GSM providers.
Thanks in advance for any advices.

If this is the case, but the end sending DTMF _also_ puts it inband,
then it is broken. This is an either/or setting; it's either inband or
out of band, but not both.
Asterisk sometimes listens for inband DTMF even when RFC2833 has been
specified because the SDP tells us what the peer wants to _RECEIVE_, not
necessarily what it will send. There are devices out there that will
tell us they want RFC2833 but send only inband... many devices are just
broken and/or inconsistent.
