[Asterisk-Users] Yet another faxing issue..

[Darren Bentley]

Hello,

fax/ata(ht286) -> asterisk/tdm04b -> pstn fax machine

I can fax out from the sip side, but I can't fax in from the PSTN side.

When I try to send a fax, asterisk sees the call and show me this:

"Redirecting Zap/1-1 to fax extension"
"Timeout on Zap/1-1"

TCPDUMP doesn't show any activity to the extension that I configured to
be the fax machine. Here's my config:

extensions.conf
;
; Zap Fax
;
exten => 8021,1,Dial(SIP/8021,20)
exten => 8021,2,Hangup

[incoming]

exten => s,1,Answer
exten => s,2,Wait,1
exten => s,3,DigitTimeout(10)           
exten => s,4,ResponseTimeout(20)
exten => s,5,Background(vm-extension)
exten => fax,1,Goto(8021,30)
exten => fax,2,Congestion
exten => fax,102,Congestion
exten => t,1,Hangup

zapata.conf

Yes, I realize faxing isn't reliable but I should at least get
something. Any ideas? Thanks,
