I am testing out inbound faxing using res_fax and res_fax_spandsp.so
My system answers the call but then sets there on the ReseiveFax line then
comes back with an error that it exceeded the maximum retries.
How would I go about debugging this? Below is my very simple dialplan code
I am using, and the fax show version gives the following as well.
FAX For Asterisk Components:
Applications: SVN-branch-1.8-r297535M
Spandsp FAX Driver: 20110122 075024
[fax_inbound]
exten => ProcessFax,1,Answer()
exten => ProcessFax,n,Wait(2)
exten =>
ProcessFax,n,Set(TIFF=/var/spool/fax_in/fax_${STRFTIME(,,%Y%m%d-%H%M)}_${RAN
D(1)}.tiff)
exten => ProcessFax,n,ReceiveFAX(${TIFF},d)
exten => ProcessFax,n,NoOp(Error = ${FAXOPT(error)})
exten => ProcessFax,n,NoOp(Status = ${FAXOPT(status)})
exten => ProcessFax,n,NoOp(Header = ${FAXOPT(headerinfo)})
exten => ProcessFax,n,NoOp(RemoteID = ${FAXOPT(remotestationid)})
exten => ProcessFax,n,NoOp(Result = ${FAXOPT(statusstr)})
I can't figure out how to turn on any debuging for this nor can I
understand why this should be failing. I am using the spandsp version that
Steve recommended (0.0.6pre18)
Any ideas or feedback would be appreciated.
Thanks

See if you can figure out anything obvious. Why are you doing a Wait(2)?
also the "Answer" is redundant in logger.conf console => warning,error,notice,debug,fax 2011/1/24 David Backeberg <dbackeberg at gmail.com>:> On Mon, Jan 24, 2011 at 2:53 PM, Bryant Zimmerman <BryantZ at zktech.com> wrote: >> I am testing out inbound faxing using res_fax and res_fax_spandsp.so >> >> My system answers the call but then sets there on the ReseiveFax line then >> comes back with an error that it exceeded the maximum retries. >> How would I go about debugging this?

Inc.) Ok I got a
inbound fax to work with our audiocodes pri gateway but I am having no luck
with a number on Level 3.
I did figure out that I can use "fax set debug on/off" and I
found
that I can add the "fax" keyword in logging.conf to see the fax
debugging.
The issue now is I am unsure how to figure out the cause of the fail. I
have attached a text file with the debug logs.
The attached file was too large so I am putting in a link to the file.
It is a virus free text file.
Fax Debug.txt
Thanks for any help.

Has anyone else seen an issue with t.38 faxing on Level 3 with res_fax and res_fax_spandsp.so What we are seeing in the packet captuers is that the call is trying to do t.38 but does not appear to be completing the handshaking. No data is being transmitted. I have included a link to my pcap of this. Can anyone give me some more insight? cap-t38.pcap Thanks Bryant -------------- next part -------------- An HTML attachment was scrubbed...
