[Asterisk-Users] Receiving faxes with spandsp - strange problem
Hello,
I'm trying to receive faxes with asterisk. My configuration is like this:
PSTN fax -> ISDN -> Cisco router with VoIP module -> Asterisk
When I try to send a fax from PSTN fax I got the standard fax signal,
Asterisk starts rxfax application and then call ends and there is no tif
anywhere. On the fax display there is still one message: Calling...
Part of my extensions.conf:
[incoming]
exten => 2933975,1,Goto(fax,2201,1)
[fax]
exten => 2201,1,Macro(faxreceive)
[macro-faxreceive]
exten => s,1,SetVar(FAXFILE=/var/spool/asterisk/fax/${UNIQUEID}.tif)
exten => s,2,DBGet(EMAILADDR=extensionemail/${MACRO_EXTEN})
exten => s,3,rxfax(${FAXFILE})
exten => s,4,Congestion
exten => s,103,SetVar(EMAILADDR=defaultuser@example.com)
exten => s,104,Goto(3)
2933975 is the number on which asterisk should listen for new faxes and
it works (in a way that rxfax is being run).
Info from asterisk console:
-- Executing Goto("SIP/62.111.174.65-f67004d0",
"fax|2201|1") in
new stack
-- Goto (fax,2201,1)
-- Executing Macro("SIP/62.111.174.65-f67004d0",
"faxreceive") in
new stack
-- Executing SetVar("SIP/62.111.174.65-f67004d0",
"FAXFILE=/var/spool/asterisk/fax/1138819786.1.tif") in new stack
-- Executing DBget("SIP/62.111.174.65-f67004d0",
"EMAILADDR=extensionemail/2201") in new stack
-- DBget: varname=EMAILADDR, family=extensionemail, key=2201
-- DBget: set variable EMAILADDR to bpiec@softhis.com
-- Executing RxFAX("SIP/62.111.174.65-f67004d0",
"/var/spool/asterisk/fax/1138819786.1.tif") in new stack
And that's all. Fax disconnects and there is no
/var/spool/asterisk/fax/1138819786.1.tif file. What can be wrong?
I saw that people are using 'fax' in extensions.conf (exten =>
fax,1,rxfax(${FAXFILE})). When this can be used? It isn't working for me...
Maybe it is an issue with Cisco router configuration? Normal calls (not
faxes) from PSTN lines work great...
I have installed asterisk 1.2.4 and spandsp 0.0.2pre23.

Everything works 100% except I do not have Cisco in between. I use TDM400 FXO card. Check if rxfax actually receives anything... Bartosz
