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 traditional telephone lines / T1

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.

I have an trixbox system setup, and all my phones are IP based, different Grandstream phones to be exact. I have some fax machines that are still around, using analog lines of course. I've read a little into FOIP and the changing of the signals form t30(traditional fax machines) to t.38 ( ip
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
Dear Steve,
SU So how does the FAX get from the fax machine to the T.38 channel

In our case we will try to strip spandsp and will use directly

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 can't understand from your mail can I use SpanDSP or not?

Yes. T.38. *

Hello Steve,
In the project OpenH323 the T.38 is supported. The easyest way is to
correct Asterisk logic with OpenH323.
