Can anyone recommend software that sends faxes over SIP? I have plenty of inbound fax to email services, but now and then I need to send a reply and it looks tacky to use one of the free web ones that put an ad on it. I know that if I wanted to pay $15/mo there are lots of lovely services but we're taking about one fax a month, maybe, here. Ideally it'd take a postscript or PDF or Word document and a phone number and fax it to that number. I have Ubuntu, FreeBSD, and MacOS boxes. Any suggestions?

Not SIP, but over TCP/IP, I have been happy with iFax from www.ifaxapp.com <http://www.ifaxapp.com/> which takes a document and a phone number and sends the document to that number. Charging is against credits which are available at varying prices. The iFax application is available for macOS, Windows, iOS, and Android. I use it on iOS and macOS. See the website for more details on inbound fax, document scanning, HIPAA, and other features. James R. Cutler James.cutler@consultant.com PGP keys at http://pgp.mit.edu

I ran into this issue when we went to a SIP phone system earlier this year. We opted to go with HelloFax and it has worked well. They do have a free account which allows you to send up to 5 faxes a month. ---- Andy Ringsmuth andy@newslink.com News Link – Manager Technology, Travel & Facilities 2201 Winthrop Rd., Lincoln, NE 68502-4158 (402) 475-6397 (402) 304-0083 cellular
I've found T.38 5o be very reliable. We have many customers using it daily. On Wed, May 30, 2018, 5:39 PM Andy Ringsmuth <andy@newslink.com> wrote:

No. Just NO. The problem is that all the modulation methods that FAX transmission use requires time stability in the analog channel, and there is no way that SIP is going to be that stable. How do I know this? A number of years ago, a cable system maker asked me to consult on why V.29 fax wouldn't work over their voice-over-coax solution. I used a 23-tone test on the analog channel for 24 hours, and found the phase jitter was off the charts -- no way that fax machines could send faxes over the analog channel. (Traced it to the timing chain oscillating across the system.) Have you considered paying the $0.50 per page to have the local copy shop send the once-a-month faxes? The other answers have far superior suggestions sending fax over TCP/IP.
In article <a09c48d0-de6c-042d-b72f-0791f541544d@satchell.net> you write:

Since the local copy shop is about a half hour drive from here, no. I don't really care if it's flaky. For one fax a month a few retries are not a big deal. But hellofax's free 5 pages a month will probably do the job. R's, John

For folks that have made it this far, you might be interested in this article that I've kept a link to for over a decade: https://www.soft-switch.org/foip.html You *can* get a fax across a G.711 connection if your throughput, latency, and jitter align and create what looks like a DS0 to the two modems. And if does it for a long enough time to get the entire fax through. Tune the fax machines so they only run 9600 bps or less, and you might just make it. Good luck. You're going to need it.

My SIP provider supports T.38. How much difference does that make? Regards, John Levine, johnl@iecc.com, Primary Perpetrator of "The Internet for Dummies", Please consider the environment before reading this e-mail. https://jl.ly

It can make a great deal of difference. You change the dynamics from: fax ------------ fax modem <-> VOIP <-> modem ------------ Into something more like: T.38 service fax ----------------------------- fax modem <-> modem <-> IP <-> modem <-> modem ----------------------------- Fax communications have a data envelope that don't play well with anything that has latency/jitter/loss issues that don't act/feel like a POTS system. Also, the envelope doesn't recover well from errors. So --- faxes fail. So, you terminate the envelop at each end, and plug them together with and IP connection. You may still have problems, but a single issue doesn't necessarily mean that you have to terminate the transmission and start over. More (and better/more accurate) details with the article I linked earlier: http://www.soft-switch.org/foip.html
I would recommend simply outsourcing it to voip.ms for $2 a month. Port your fax DID to them. Incoming fax arrive as PDF in your choice of email inbox. You can send outbound fax from a predefined list of your own email addresses, destination to fax@voip.ms. Put the destination phone number in the subject line, attach the document to be faxed as a PDF. There is also an https web portal for uploading documents to be faxed, there is no tacky addition of advertisement. https://wiki.voip.ms/article/Virtual_Fax On Wed, May 30, 2018 at 1:13 PM, John R.

Freeswitch's t38 support also is said to work well. Hylafax, iaxmodem and asterisk has worked well for mulaw faxing, provided a low-jitter path to the pstn provider, but lately I've been using the above path. Of course that is probably only one fax every few months. -JimC -- James Cloos <cloos@jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6
Hi All, Looking for similar, but other one. Have Asterisk with E1 connection to PSTN (not VoIP). Is there some software to let it work as a fax and modem? 30.05.18 23:13, John R. Levine пише:
