[asterisk-users] (OT) HylaFAX, IAXModem, Asterisk

[Steve Totaro]

I have all three running on the same box.  I say OT because it appears 
asterisk is doing it's job just fine.  It must be an IAXmodem or 
faxgetty (hylafax) problem

When faxes work, they look great.  I have ten IAXmodems setup with 
different ports and they register fine.  I have ten faxgettys that 
startup fine.  I start the IAXmodems and then faxgettys in inittab.  
They are setup as a roll down in the dialplan.

Everything works for a while but at some point (not sure if a regular 
interval or random), they when a call is attempted, the channel reports 
back that everyone is busy.  Sometimes it is just one and the next grabs 
the call, sometimes all of them and the call goes to congestion.  
Faxstat shows all faxes as running and idel and show channels in 
asterisk reports zero.

I am losing about 40% of inbound faxes at times when the system is 
"working" and 100% when it is not.  I put together the configs from many 
different resources found on the net since no single Howto seemed to 
work correctly which got me to this point.

Does anyone have any clue why this happens?  I have examined every log I 
can think of and there are no errors.

Thanks,
Steve
