Re: [hylafax-users] Send fax ERRORS: COMREC invalid response received to PPS - No response to PPS repeated 3 times

["Luigi Carrieri" <l.carrieri@xxxxxx>]

Thank you Lee for your help.
Note that actually hylafax is installed in a production
environment and it is used for daily fax communication to/from
our customers. For outbound faxes we use hylafax
as a mail-to-fax gateway service. Documents to fax out are
*ALWAYS* PDF files attached to mail.

So I *MUST* be careful that whatever test does not degrade the service.

Here is some more information:

1. In <hylafax-dir>/var/spool/etc/config.ttySx per-modem configuration file
I 
put the following parameters
   Class1ECMSupport:	NO
   ModemSoftRTFCC:   	NO

2. In <hylafax-dir>/var/spool/etc/config per-server configuration file I put
the following parameters:
	JobReqBusy:		180
	JobReqNoAnswer:	180
	JobReqNoCarrier:	180
	JobRetryBusy:	20
	JobRetryNoAnswer:	20
	JobRetryNoCarrier:10
	RingTimeout:	15000

3. I sent the same document to both the faulty fax equipments (as in my last
mail):
- the first one (see success-7586.log file in attachment) received the fax
successfully;
- the second one (see fail-7608.log) never received the fax because of "busy
signal detected" error. But the receiving fax equipment was NOT busy! 
Hylafax tried to dial many times and it was possible to hear the sound of
carrier for less than a second but then the initial handshake was suddenly
interrupted. 
The I tried to send a fax to this machine from another desktop fax equipment
and
all went fine. 
  
What do you think about this strange behavior? 
Thank you again.
Luigi

As for the DCN after PPS-MPS (the first log).  Does that happen *every* 
time you send *any* fax to this destination?  We've seen at least two 
reports of this kind of thing going on, but we have not been able to 
nail anything down because in the first case that I investigated the 
problem suddenly disappeared on its own, and in the second case the 
reporter never has followed up with test results.

If it is not completely reproducible 100% of the time then please 
determine under what conditions it is at least reliably reproducible, 
and report back.  If you can get it 100% reproducible, then follow these 
steps:

First, call the receiver up and have them reboot their fax machine.  
Then retest.  If it works then report back.  If not, go to the next step.

Second, send them a test fax like this:  echo " " | sendfax -n -F "" -t 
1 -T 1 -d <fax_number>   If it works then report back.  If not then go 
to the next step.

Third, send them a test fax like this:    echo " " | sendfax -1 -n -F "" 
-t 1 -T 1 -d <fax_number>

Fourth, in your modem config file put "ModemSoftRTFCC: no" and then send 
them a test fax like in the third step.

Fifth, send them a test fax like this:  echo " " | sendfax -n -F "" -E 
-t 1 -T 1 -d <fax_number>  Report back.

Hopefully that's enough testing for me to get an idea as far as what's 
going on.

As for the "no response to PPS" error.  Please call the receiver and 
find out if they received any of the page at all.  And if they did, then 
please see if any of the page was missing.  Please report back on that.  
Also, following the steps above would be quite helpful for this case, too.

Thanks,

Lee.
