[Asterisk-Users] spandsp and app_rxfax(alternative topic:t38modem)

[Jeff]

While I appreciate your response (as much as anyone else's) I wonder if you
are referring to the link on the FAQ here
(http://www.opencall.org/faq/x26.html)? It tends to blame Fax modems where I
stated that I ALSO used a Fax machine. No modems just a big old plain paper
fax -remember those everyone  ;-)

Someone else pointed to a shared interrupt issue and despite not having any
other zaptel issues with * (leading me to believe that I did NOT have one) I
tried disabling all onboard devices and used a good ole 3COM NIC just to be
sure but I get the same results using a trunk (FXO) and a station (FXS) port
as I did in my original post (as does Ryan the OP in his).

Here is the output from /proc/interrupts on this clone:

           CPU0
  0:     616244          XT-PIC  timer
  2:          0          XT-PIC  cascade
  5:        716          XT-PIC  eth0
  8:          1          XT-PIC  rtc
 11:     590558          XT-PIC  wctdm
 14:       4327          XT-PIC  ide0
 15:       5087          XT-PIC  ide1
NMI:          0
ERR:          0

I have nothing else on this box and no other traffic so I will try it in a
Compaq deskpro and post my results...

Sorry I couldn't help you Ryan...

and thanks to others for trying.

Jeff
