1 Faxes usually do not work over straight IP. I know
they can and many including myself have had success the mechanics of the IP
network usually won't allow it.

On the same LAN it should work OK, using a dedicated NIC and a
crossover cable to the HylaFax server is the best way if possible.

2 If you are using anything other than a/u law forget
it.

I use SLIN

3 What is the connectivity between the Asterisk boxes?
If they are plugged into the same private backbone (ie Same Ethernet
network) you have a fighting chance. If not, it is up to the Gods of Network
congestion.

True. Again, a direct connection to the fax server via crossover
cable is the best method.

4 You may want to read up on the IAXModem pages, Mr,
Underwood, explains the use of IAXModem and gives a few pointers on useing
the IAXModem to terminal/originate calls on the same machine that has the
TDM circuits and use remote serial to bring the fax data back to the hylafax
machine.

I think his is the root of the problem. Not understanding how
IAXmodem works with HylaFax.
Thanks,

Hello! I need to send Faxes from an Asterisk box to an Asterisk + Iaxmodem +
Hylafax installed on other box. I have setup IAX trunks between this boxes,
all works fine but can?t send faxes from one to other, Im trying with or
without NVFaxDetect application but does not work. Is there a way to get it
working?. If I connect a fax machine directly to Asterisk with Iaxmodem and
Hylafax, I have no problem. But between Iax Trunks nothing happened and the
fax machine registered on the first PBX give me a communication error.
Thanks for any help or idea to setup and get it working.

Crossover will certainly help with IP issues such as latency.
I think your problem is that you don't really understand how IAXmodem
and Hylafax work.
Here is a link to a well documented Hylafax installation that I did
for a fairly large mortgage company. Alex came in after me and did a
great job documenting my work (and taking credit).

box have Asterisk 1.2 and the other have installed Asterisk 1.4, I can do
calls between boxes without problem. So the solution for this model is
connect both server through a crossover cable?.
