[asterisk-users] app_txfax, app_rxfax

[Craig Guy]

That is not true regarding voice / fax detection with iaxmodem.  If you are
running zaptel, then let it do the fax detection and have the iaxmodems
called from the fax context.

Another question along these lines : How does everyone one fax detection 
on a sip channel? The only thing I've found is NvFaxDetect - anyone know 
of anything else?
