I'm really not sure - I think you might have to try it! Gordon The best way to do this is have a dedicated fax line, do not use fax detect, and route any calls to that zap/dahdi port to where you have the dedicated fax or just keep the fax out of Asterisk entirely. I am used to large scale fax setup, so I am more familiar with DIDs assigned to FAX and then use IAXmodem to Hylafax. Sounds like bigtime overkill for your use. You could look at www.trustfax.com (no affiliation but a happy customer), better service than www.efax.com as far as I am concerned and better pricing. My faxing requirements are very low though. Most customers that insist of dual use POTS lines invariably complain about the delay, which I have to explain, especially if they have caller ID too. -- Thanks, Steve Totaro +18887771888 (Toll Free) +12409381212 (Cell) +12024369784 (Skype) ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
[asterisk-users] setup for fax machine
Becasue of all the issues with fax over voip, we want to use pstn for our fax machine, but not dedicate a line just to fax. I'm thinking of having asterisk answer the pstn line, check for fax tones, and route appropriately. In zapata ( chan_dahdi ) set faxdetect=incoming then the dial plan would have [incoming-pstn] exten = fax,1,Dial(DAHDI/1) ; the fax machine exten = fax,2,Hangup() exten = s,1,Answer() exten = s,2,Dial(DAHDI/2) ; internal extension .

Yes, it'd work as long as Asterisk doesn't make a mistake on fax detection. From what I've read, it's sort of an art (Fax Detection that is).

Another thing you can do is get a comswitch -- they are pretty cheap and have been around for years. http://www.commandcommunications.com/products.php IMO they work pretty well. I use these as a backup. I use VoIP only at some sites and the fax line is used for the DSL. The comswitch is connected to the line and then connect the asterisk machine (using a cheap winmodem), fax machine and a red WECo 2500 clone. So if the DSL goes down the calls get routed through that phone line and the comswitch routes them to the Asterisk machine and the IP phones ring like normal. If the PBX goes down or the power for a long time, they can use the Red phone The main motivation for going to this setup was a low cost way to keep 911 working while trying to stay 100% voip . The comswitch was installed so in case 911 needs to call back it won't go straight to the fax. The use of the line as a backup ended up being an unintended consequence, but it seems to work well. This setup works very well, but if you are using this on a main phone line then be advised there will be an extra 1-2 ring delay -- the comswitch actually answers the call when it comes it and does fax detection. I also see these installed in many retail stores -- normally they will have 3 lines in a hunt group -- the 3rd line is shared between the fax and the hunt group using the comswitch. ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
