I figured out the problem. Actually the sending fax machine speed was set
as 33000 bps, later I set to 14400 bps and in my dial plan, I forcefully
set to use T.38 protocol. After that I was able to receive fax.
Thanks
Hi Tim,
I'm using Asterisk 10 and on Cisco GW the protocol is set for FAX is T.38
and when I try to send the fax from a fax machine i.e. HP 3180, I'm getting
some warnings as listed below;

Hi Tim,
...
While the fax machine starts to send the fax after a while it gives
the message, 'Fax failed' with error code: '388'. Is it the end
point fax machine issue or else? Please assist me out to resolve
this issue at earliest.
Please do not email me

Hi all,
Couple of things I would like ask, does Asterisk provides free
license for FoIP (for 1 channel) or need to purchase it? Couple of
years back, I was able to send and receive the fax using Digium T1
card, in term of FoIP how can I able to receive fax from

Hi Tim,
Thanks for your response. Here is my topology as listing down below;
PSTN Line -- Cisco Voice GW -- IP Cloud -- Asterisk
Will Asterisk able to receive the fax (as in topology above) using
its' fax module? In sip.conf I enabled fax detection and T.38.

Christopher,
Also, how am i supposed to get my fax machine onto my ethernet network? i
assume it needs some kind of Aanalog Telephone Adapter, just like with VOIP.
You need a T.38 capable ATA. There are a few but not too many. I
believe the Grandstream ATAs have T.38 support or will have it
Hi Miroslav,
It sounds like you don't really understand what T.38 is. You need some
form of modem to get from a normal FAX machine to a T.38 channel.
spandsp can do that. A normal FAX modem can do that. You need a modem
somewhere, though. That is why developing the FAX modems was the first

I tried this a lot, but with no sucess , even in a local network , there
is always some loss and you receive only chunks of the original file .

assuming that some of these CODECS do error correction and drop any
information that hasn't come through instead of doing error detection and
request to re-transmit the lost information, is somewhat expected. Are there
any Fax over IP protocols?
Yes. T.38. *

Someone should put a bounty on T38. We're using spandsp right now and

We used spandsp on the voip side. Our inbound vendor sets the call up
G711 and spandsp answers. It's a bit slow as it seems to only negotiate
v29 terbo, but it works.
Finding the correct version of libtiff was a pain. One sub version off,

Hello Steve,
There is another way to send fax if you use Fax Machine on some FXS
port.
and exactly how does that get the FAX into the T.38 channel? :-\

In the project OpenH323 the T.38 is supported. The easyest way is to

Maybe, but from a quick look last year it didn't appear easy to make

I switched to spandsp rather that purchase an expensive multi-port
FaxModem card for a fax server.

Any chance of a clue as to how you did it?
I've had some success utilities from Hylafax, it works perfectly on one
machine but fails on my actual * box.
