[asterisk-users] Unable to receive faxes

[Laurent CARON]

Hi,

I'm experiencing a quite strange behavior while trying to receive faxes 
through Asterisk (either directly through app_rxfax or with spandsp + 
hylafax).

Config:
HFC quad BRI card (3 T0 connected to the card)
Asterisk 1.4.21
asterisk-app-fax 0.0.20070624-2
hylafax 2:4.4.4-10.1
libpri 1.4.2
libspandsp3 0.0.4pre16

/etc/zaptel.conf
loadzone=fr
defaultzone=fr

span=1,0,3,ccs,ami
span=2,0,3,ccs,ami
span=3,0,3,ccs,ami
span=4,0,3,ccs,ami

bchan=1,2
dchan=3
bchan=4,5
dchan=6
bchan=7,8
dchan=9


/etc/asterisk/zapata.conf
[channels]
language=fr
switchtype = euroisdn
signalling = bri_cpe_ptmp
pridialplan = unknown

nationalprefix = 0
internationalprefix = 00
echocancel=yes
rxgain=1.1
txgain=1.1
group = 1
context=zaptel-in
channel => 1-2
channel => 4-5
channel => 7-8


/etc/asterisk/extensions.conf:
exten => 0258,1,Answer()
exten => 0258,n,Set(FAXFILE=/var/spool/asterisk/fax/fax-0258.tif)
exten => 0258,n,rxfax(${FAXFILE})
exten => 0258,n,NoOp()
exten => 0258,n,Hangup


Here is the asterisk cli output:

     -- Accepting voice call from '' to '0258' on channel 0/1, span 1
     -- Executing [0258 at zaptel-in:1] NoOp("Zap/1-1", "") in new stack
     -- Executing [0258 at zaptel-in:2] Set("Zap/1-1", "CALLERID(num)=") in 
new stack
     -- Executing [0258 at zaptel-in:3] Goto("Zap/1-1",

     -- Goto (default,0258,1)ff o

     -- Executing [0258 at default:3] RxFAX("Zap/1-1", 
"/var/spool/asterisk/fax/fax-0258.tif") in new stack
     -- Channel 0/1, span 1 got hangup request, cause 16
     -- Hungup 'Zap/1-1' channel

The resulting tiff file is nearly empty.

Do anyone have a clue about this issue ?

What is "cause 16" about ?

Thanks
