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.

I've the same setup with FreePBX and NVFaxDetect. Works fine.

OK, there could be a few items here:



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

Quote:

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,

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).

I am trying with ulaw/alaw codecs, both boxes are in the same LAN. The first
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?.
