chan_dahdi.c, dtmfmute, rtp.c
...code that handles this in the case of rtp
to rtp, it says "Ignore potential DTMF echo...".
I also looked at chan_dahdi.c the only way to ignore DTMF is with
disable_dtmf_detect() which seems to be used when Native bridging, so
it's not what I am looking for.
I found the chan->dtmf_tv variable in channel.c which specifies a gap
between DTMF, but it requires 45 milliseconds, in theis case the echo is
113 milliseconds later, and on a different channel, so that doesn't drop
the duplicate DTMF.
How can I tell asterisk that the DTMF coming back is an echo and not a
new DTMF...
