Hi Steve,
I was waiting for your answer :-P

I started to use your SpanDSP library since some years ago but,
unfortunately, my experience was only related to lab or personal use
and/or systems with PSTN or BRI cards and low fax volume where it's
impossible to have valid statistics.

I read the link you provided me and now I'm confident that IAXModem
running on the same asterisk box with a PRI board is something I can
propose to my customer.
There are some other variable I would like to evaluate, like, for
example, what type of PRI connection people of this list are using in
their fax servers.

Thank you for writing SpanDSP and best regards,
Marco Signorini

I'm not sure where you got that idea. Most comments about iaxmodem + 
HylaFAX are very positive. It does, of course, require a reliable 
connection between iaxmodem and the PSTN, but most people set these 
things up in a reasonably well controlled environment. There are some 
notes at http://www.soft-switch.org/spandsp-soft-fax-performance.html 
about the results of serious real world volume testing of iaxmodem.

A single server that I administer, receiving 12,000 pages and sending

I would strongly disagree with this statement. 

I'm running 3 systems.  All 3 are PRI/iaxmodem/HylaFAX+.  I may see a 
failure maybe once every other month.  Usually it's because the end user 
has cancelled.

We average around 180 faxes a day

Hi Gordon, thank you for your answer.

It's not mandatory to use an external box to handle the PRI. I was
thinking to use a Patton device instead of a TE120P just because I would
like to be able to switch to T38 in the near future or if working with
inband faxes will reveal problems.
I'm open to any suggestion, being in the initial requirements analysis
stage.

External devices, also, let me able to select a server independently by
the PCI, PCIXpress or any other connectors will be ready in the future,
maximizing the customer investment... but this could be the less
interesting part.

Thank you to All People answered me on this subject.
Analyzing your answers, seems that fax handling is still today
problematic with IAXModem and Hylafax... or I'm wrong?
What about other solutions?

I had a very good success rate with multitech modems connected to fxs card
and calling out with T0 (bri) I had 3 modems in total, - 1 receiveing 2
sending, they were heavily loaded and i had very low failure rate 20 000
faxes and only 3 failed (!) from 3 only one due to incompatibility (brother
model know issue) and 2 bad line. I dont inclide here wrong numbers.

My recommendation would be to stay away from VoIP even T.38 whenever possible.
That said yout best option is to use TDM, for that you can either use
1 single span T/E1 from digium and an analog TDM card for FXS.
Or you could uee a dual span T/E1 card and a channel bank with FXS
ports. While the later is more expensive I prefer that, since it gives
lots more options in the long run.

Well, as i said before this setup works quite fine now. What doesn't was 
when using hylafax
 over IAXmodem on two separate servers.

And hardware faxes make a much better job at handling faulty 
communication than hylafax

You'll find that faxing over IAX is problematic at best.

If this is your only option, I'd suggest that you have HylaFAX+ running 
at both ends.  Capture the faxes coming off of the E1 as PDF, do a 
remote send to the other fax server and have the remote HylaFAX+ do the 
faxing to the fax/copy machine.

Well the Fax machine and the E1 input are wired in two differents locations,
and at the time of the setup all links between the two servers rooms where
used for networks and other stuff.
Also the first asterisk already had a TE220 and a B410p and i feared adding
one more card wouldn't be a great idea.

Couldn't you hack a faxsend script for hylafax to do this ? my first setup
involved sending all fax by mail to some people in pdf form but to speed up
filtering spam & all, i also sent the first page of the inbound fax in a 
jpg image
so it appear directly in the e-mail

The TE220P and the TDM800P are in different Asterisk boxes? Any particular 
reason for that?  I now have an E1 coming in to the asterisk box and 
IAXmodem and HylaFAX to receive faxes which works flawlessly.

Outbound i still have an old faxserver connected to an old analogue line 
though.

My faxing needs require that i have a hardcopy printout of every fax that 
is sent like a reduced size of the fax sent on one A4 together with all 
status info (Fax number it was sent to, status, duration, ID of the 
receiver, date, time etc.). So far i couldn't find any solution that does 
that.

Out of curiosity, why an external box rather than something like a TE120P

Personally, I think you're adding complexity and can't see why that would 
be better than an on-board PRI card...

Re: [asterisk-users] Faxing success rate on PRI

2009-03-08 Thread benoit

Here is my current setup:

E1 => [Asterisk with TE220p] => IAX Trunk (routed network) => 
[Asterisk with TDM800p] => Fax/Copy Machine

This seems to work fine, a few failed Fax or very slow sending/process 
sometimes but no complaining
users, so this must be ok :)

My previous try was:

E1 => [Asterisk with TE220p] => IAX peer (same network) => HylaFax 
machine with IAXmodem

While the users did like the facility of receiving PDF documents, we had 
many calls for people unable
to send Fax to us, so i kinda ditched to solution. I've updated the 
setup to use IAXmodem/Hylafax on
the first asterisk machine but until now i haven't tested it.
