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              Bryant Zimmerman (ZK Tech 
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.
