Asterisk, TE110P and outbound faxes

Asterisk Asterisk Support
1

Hello,
I’m trying to use asterisk to send fax, too…

We have a Digium TE110P, and we are using asterisk 1.2.x (AAH2.2)

We can dial out, dial in, fax in without problems (well… now without problems :smile:

However, we cannot fax out (we are using asterfax); after some tests we can dial out and if I call myself on my home number I can hear the fax tone (generated by asterisk/digium card)

But, If I call a real fax machine, we get this: (where is the problem, if called people can hear the “beep” of asterisk-fax? why the fax machine hangup?)

I tested with Winfax on one PC…

It says:

Answering…

Linked to remote fax… (my asterisk/asterfax)

Training…

and then hung up.

I have the exact same problem.

I can’t wonder where to look anymore… Seems like it’s an Asterisk problem of some sort, because I’ve tested fax transmission using call files, bypassing any other addons to the system - and the same thing happens, result 14 and the line being dropped and fax reporting “communication error”.

Also when transmiting fax i can hear the fax tone when i pickup the call. Maybe Asterisk is trying to send faxes using some weird protocol that my 2 faxes don’t like and hangup? Don’t know…

Receiving faxes is fine tho…

The problem appears to be a permission issue.

Error 14 is reported by the txfax application when it can’t open the tiff file.

This is an issue that I’m currently investigating for an AsterFax user.

It appears that the tiff file written by AsterFax for txfax to transmitt does not have the correct permission set.
AsterFax must have read/write access to the directory and Asterisk must have read access to the directory and the resulting file.

I have been able to reproduce the problem but I’m still working through the details for a recommended configuration. When I come up with one I will post it on the asterfax forums.
This is not likely to be before the 23th of Jan as I’m currently on leave.

The problem was a bug in AsterFax beta 5 (and earlier).
The problem has been resolved in beta 6.

Appologies for the inconvenience.
