Hi all, the company I work for has an aging Digital PBX attached to an E1. This PBX has a few analogue lines, one of which we use a 'traditional' fax machine on. I want to upgrade our PBX and Asterisk is almost a perfect fit. The only problem I can't seem to find a working solution for is Faxing. I don't want to use Hylafax or other similar methodologies. I believe there maybe someway to bridge an Analogue FXS port to a channel on the E1? Basically I want to mimic what we have now. 1. Any person can send a fax using the fax machine, and the PBX picks the next free channel on the E1. 2. A fax call can come over any channel on the E1, and the dialed number is matched and sent to the analogue FXS port of the PBX to be received by the fax machine. Is there anyway I can do this in Asterisk that will work seamlessly? I have not yet purchased any hardware, so recommendations would be greatly appreciated. (I believe some of the problem exists due to timing, does any hardware; E1 card / Analogue card; support linking a timing signal together?) Sangoma, Digium, Pika? Thanks all for any help on this one.

Hi, For that you need to purchase sangoma FXS card and connect your fax machine in the fxs card. so that the fax machine will seems as an extension for asterisk. whatever fax comes in it we can write a rule where a fax nmber will reach the extension connected fax machine.

One is to use iaxmodem and hylafax. This option works the best. You can try to use an analog adapter or card to connect a conventional fax to but this is not allways reliable. I have spent alot of time working on faxing with asterisk. If you need any help you can email me and I will send the links and scripts that I have to help you in your setup. FYI, They are all for RH/CentOS. Hardware, how many phone and trunks do you plan on using? Digium cards for analog phone's and faxes work very well, linksys makes very good ATA's too. Digium or Sangoma T1 cards are the most suppoted that I have seen. but there are others. OS, there are alot of different *nix OS's that are out there. Pick the one that you are the most comfortable to use. Asterisk was developed on RedHat though. Depending on your needs for support I would suggest either EL4 or CentOS4 with Asterisk 1.2. There are alot of people running 1.4 in production but the commercaial version of Asterisk is still on 1.2 Jonn
As another suggested the Sangoma cards should work. However we need someone to write a frontend to Steve Underwood's wonderful spanDSP library. This will allow us a T38 gateway of sorts meaning you can connect a Linksys ATA using T.38 and we can say that (assuming your fax machine strictly complies with the relevant standards) faxing will work with 100% reliability, thats a bit more assuring that it "should work," no?

Since both legs of the call pass through the same E1 interface card asterisk can bridge the call on the card itself and the timing issue should become moot. I have not done this nor have any hands-on experience to share, but I have done some research into this in the past. This is also the method Fonality recommends for customers of their asterisk based system: http://help.fonality.com/index.php/Fax_Machine_and_Modem_Support_in_PBXtra -Dave
Depending on how many faxes you have coming in a simple fxs/fxo card will do the trick .. either Sagnoma or Digium or any others you could also use any decent ATA.. Asterisk only needs to know its a fax and what dialed number it came on to route it to the correct fax machine. Asterisk would just act as a pass thru..
