tbsky,
I really-really suggest you open another issue titled "DTMF duration
detected wrong", put your last comment there and attach snom-dtmf.txt

Otherwise this (11740) gonna stay forever attaching all DTMF related
problems to itself. So none of them will be closed.

You definitely has reproducible case when DTMF_END frame len field gets
improperly initialized for some reason.

[Feb 14 09:09:14] DTMF[20816] channel.c: DTMF end '1' received on
SIP/3340-0825f060, duration 74617280 ms

An I would repeat myself: 

"...which means frame's len field value is way too large. This looks like
bug in rtp.c or something. If I had to investigate such an issue, I would
be interested in:
1. inclusion of rtp debug into debug output in addition to DTMF debug
2. value of rfc2833compensate parameter for the peer.

But again, I would fill another issue. "
