Summary:                    Called Party's inband DTMF removed almost entirely
with overlapdial and non-native bridging
Description: 
If you are using inband DTMF (tested on two Zap channels), and two bridged
channels are not bridged natively (e.g. because you are using MixMonitor),
and the incoming call used overlap dialing, and the Called Party tries
sending DTMF, you hear a blip and perhaps a few milliseconds of tone, but
not enough for the DTMF to be recognised by an application on the Calling
Party side. (Asterisk does not recognize the DTMF either). It is being
trimmed to within a millisecond of its life. Note, that the Calling Party's
DTMF is OK.

Sorry for the lapse in time here, but I'm not to sure how to proceed.

Seb7: Have you gained any more information either through an upgrade or
more experimentation?
