RE: [Asterisk-Users] asterisk and fax over ip - concept
That is a nice thought and takes care of problem with fax transmission over
IP. However not applicable in my case though. Most 'fax users' will not have
Asterisk on site but some other fxs gateways instead. Also from what I've
read RxFax tends to cause problems.

Would the following be a doable solution:
1. An Asterisk-box on site with FXS
2. Plug Fax into FXS
3. User uses facsimile machine to call a number - Asterisk answers
4. Stores called number into variable ${FAXDESTINATION}
5. Use RcfFax of * to store fax within asterisk
6. mail stored fax together with ${FAXDESTINATION} off to central office
with outgoing PSTN?
No PSTN line needed, user does not need to change his/her way of doing
things.
If you want to provide feedback with regards of fax success, prefix the
phonenumber with a 3 letter account number specifying the sender to be
used for later eMail notification.
Just a thought.

[Asterisk-Users] asterisk and fax over ip - concept
I will be using Asterisk to connect remote offices to PSTN - over IP (SIP). These offices will use fxs gateways such as madiatrix and audiocodes to send VoIP traffic to Asterisk. Asterisk will in turn push their traffic to PSTN. The other way round will also work ie. Asterisk will forwards traffic from PSTN to those gateways (offices). The problem that I have though is that most companies send and recive faxes - and so will these. I dont want these offices to bypass faxes directly to PSTN but would somehow like to workaround fax over ip and Asterisk. What came to my mind was to add an fxo gateway (connected to PSTN) beside Asterisk to break out faxes to PSTN. Such a fxo gateway could communicate with the fxs gateways at customer premises and could reliably transmit faxes using t.38. The way I would imagine it is as such. When Asterisk would see a 'call' coming from a specified number (assigned to a sip port of an fxs gateway) instead of bridging the call directly to PSTN over a zap interface the 'call' coule be forwarded to the fxo gateway (over sip) that could reliably handle the 'call' (fax transmission). Would the t.38 transmission be properly handled by the t.38 supporting end points whith mediastrem passing through Asterisk ? (dont have much experience with t.38) Has anyone ever tried anything similar / different / wierder to try and deal with fax over ip and Asterisk ? Any suggestions and comments are welcome.

What I would do i this situation is work out a fax -- email gateway. Best case this could be done entirely with software on the asterisk box, worst case a faxmodem hairpinned into an fxs card using hylafax. Instead of a fax machine, the people could have a scanner, and they would send their fax as an email attachment. Likewise recieved faxes could be sent directly to a printer, or to an email address, or even stored and made accessible on a webserver...

Re: [Asterisk-Users] asterisk and fax over ip - concept
Hi! What I would do i this situation is work out a fax -- email gateway. Best case this could be done entirely with software on the asterisk box, worst case a faxmodem hairpinned into an fxs card using hylafax. Why exactly would hylafax be a worst case solution only, why would you tink that that the Asterisk solution is better at all? Instead of a fax machine, the people could have a scanner Hmpf... I've always found that to be a very bad replacement for an analog fax, at least as soon as you have to deal with more than 1 page. Plain old analog fax machines are a very well designed devices... ok, for receiving faxes some unified messaging or e-mail attachment is fine, on that part I can agree.

I guess it depends whether the people are doing more print-to-fax sort of things or feeding the fax machine with large amounts of paper... While this is just starting to get a little OT, there is another option - but it requires a little change in mindset and work habits. Instead of blindly faxing, consider setting up a PC with a decent ADF scanner. Chances are that the document being faxed is going to either be mailed as well, or just filed. It could also be a standard document that you fax to many people. The PC could drop the document as a PDF, multipage TIF, or whatever to a shared folder. The user could then email the document image, use the PC fax software (like Hylafax), or just archive the document for future reference. The old paper copy can go into deep archives (sometimes even offsite - which may be a good thing from a records keeping aspect.) Frankly, I hate filing lots of paper. Chances are that I am going to have to get the damn thing copied for someone, the paper gets lost, etc. If it's electronic, I can even look at it from home or on the road. If I'm in a meeting and someone starts questioning the details of a contract, I can pull the thing up and resolve the question instantly. All my files are available to me or other people I delegate authority to access, whenever and wherever needed. There was a big push for paperless offices, which for the most part failed. Partly, disk was Very expensive, along with scanners, special HSM software, etc. It's a LOT more affordable and practical today. ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Why exactly would hylafax be a worst case solution only, why would you tink that that the Asterisk solution is better at all? Not so much a hylafax issue, but in order for my software maintenance requirements and management simplicity I like to keep as much as possible in one app. Integration with asterisk would simply mean less applications running on my systems to worry about. Very nice to have in case of large number of boxes deployed. Instead of a fax machine, the people could have a scanner Hmpf...
