[Asterisk-Users] Fax support?

[TC]

I beleive there is some issue/bug in the low level fax detection logic in
dsp.c
see dtmf_detect
if you look in  chan_zap.c around lines 3066-3088 & stick a DEBUG msg in
there
you prolly notice that that the FRAME type is not set to DTMF & the subclass
<> 'f'

Mark says Thr or Fri this week he may have some time to look at this he
we get a hold of him on IIRC ..

(unless we have some other dsp gurus who know anything about  goertzel & fax
energy harmonics :)
