Hi men,

Just a quick howto install FAX.

In my case, I am playing with Asterisk 1.6.1, downgrading my previous 1.6.2 which can't have FAX modules for now.

You must synchronise the correct FAX version with your Asterisk version !

After having received your FAX license and registered it with the "register" tool, you must download and execute the "benchfax" to know what is the correct FAX module version for your Asteris kserver environment :

wget http://downloads.digium.com/pub/telepho ... 0.7-x86_32

chmod 500 benchfax-1.0.7-x86_32

./benchfax-1.0.7-x86_32

After few minutes (5 x 14 tests !) you must read the result and know what version you must download.

Mine was "opteron".

Then, download the two necessary modules (change for yours depending Asteirsk version and CPU) :

wget http://downloads.digium.com/pub/telepho ... _32.tar.gz
wget http://downloads.digium.com/pub/telepho ... _32.tar.gz

tar xzvf res_fax-1.6.1_1.0.8-x86_32.tar.gz
tar xzvf res_fax_digium-1.6.1_1.0.8-opteron_32.tar.gz

Then, copy the two modules to the good Asterisk lib repertory :

cp res_fax-1.6.1_1.0.8-x86_32/res_fax.so /usr/lib/asterisk/modules
cp res_fax_digium-1.6.1_1.0.8-opteron_32/res_fax_digium.so /usr/lib/asterisk/modules

Restart Asterisk and you can check if ok by entering any command starting by "FAX" from the Asterisl CLI :

asterisk*CLI> fax show version
Fax For Asterisk Components:
Applications: 1.6.1_1.0.8
Digium Fax T.38 Driver: 1.6.1_1.0.8 (optimized for opteron_32)
Digium Fax G.711 Driver: 1.6.1_1.0.8 (optimized for opteron_32)

That's all !
Thank you Digium guys !

Best Regards,
Francois BERGERET

Okay, cool.

You must have downloaded the tarballs within the first few hours they were available. We had a build error with them that we corrected. We did not rev the version number of the tarballs though.

Please download res_fax and res_fax_digium again from the Digium downloads server. We've seen your specific problem before, exactly, and we've fixed it with the new tarballs.

Cheers.

Malcolm,

Great Sir! that worked so i downloaded tarballs within first few hours of release and now i removed the old and installed new and its working.

Now another help i need....! hope you dont mind?


Im using AsteriskNow 1.5 which has freepbx as GUI and most things i do is with GUI and not hand edit as im not good at this.....so if you can please show me how to do make a fax working with FreePBX or a dialplan example for sending and receiving fax....!

as on FreePBX there is Fax Detection application is NVFaxdetect would that word with Digium Fax Application after successful tests we will go for commercial one and will continue using free version for testing purposes.

please provide step by step guide. cant thank you enough Malcolm am i complete newbie for Linux and Telephony world.

Hey f6hqz,


Thank you very much for your guide i actually followed that but the problem was with source tarballs which is solved.

now if you can really guide me through a step by step guide for making it work with AsteriskNow 1.5 and FreePBX as GUI, also some pointers on how to do windows PC to Fax (send/receive). that would be a great help.

Just d/l the tarballs again, still same problem. Any new suggestion to troubleshoot? This forum post is the only place this string exists according to google.

Howdy,

Does res_fax.so load correctly?

[mykhyggz]

Of course, I just posted some error on the module load.

However, it appears to work... just haven't gotten fax detection working, so as to share this with incoming voice calls...

Since I'm replying to myself, maybe I'll report back if that works as well.

Basically, I just upped the rx value and the fax worked. Even with hpec apparently still active. Hmm. Maybe it'll work to detect the fax tones now and do the exten => fax stuff, too!

[mykhyggz]

So, I guess without nvfaxdetect, I can't do what I'd intended. I'll wait until http://www.spinics.net/lists/asterisk/msg88489.html Justin Newman does the promised porting.

No matter. I can just tweak the dialplan if I'm actually intending to receive a fax. Point is, it works.

[mykhyggz]

My bad, the problem was a typo in my extensions.conf. All good.

And as for the other error, I quote: "The FAXSTATUSSTRING channel variable is not used by the Open Source Asterisk trunk app_fax module."... which seems a *lot* like it's related to:

Error loading module 'res_fax_digium.so': /usr/lib/asterisk/modules/res_fax_digium.so: undefined symbol: ast_fax_state_to_str ...

Anyway, I can't get it working again ,
