You might be able to do something with an ISDN/SIP gateway device (probably one that supports T.38 to give you more options in terms of software that will work with it) and Asterisk and either its built-in fax support or passing the call to a setup with iaxmodem+hylafax. Or with freeswitch (not in ports mostly due to their policy on bundling libraries). I'd probably try to outsource it personally. Expect some headaches, especially if you haven't dealt with voip software much..

See comms/hylafax! We've had AT-speaking ISDN "MoDem"s. It was fiddly but worked once it worked. I know of large "Office Printers" that can handle this job... Not saying it's better that way.

Hi Stuart thanks it is for a client who wants to take faxes multiple numbers in on a hardline ... and then convert to email and vice versa any suggestions you have would be appreciated...

Hi Tom, Mandatory reference material to restore retro knowledge where applicable. Integrated Services Digital Network (elements) https://en.wikipedia.org/wiki/Isdn#ISDN_elements BRI (2B+D) https://en.wikipedia.org/wiki/Basic_Rate_Interface PRI (30B+2D) https://en.wikipedia.org/wiki/Primary_Rate_Interface > Would need more information about what the "legacy services" are before > it's possible to make any kind of suggestion (but apart from some data > services on BRI which might work with an async TA, it's not really going > to involve OpenBSD in directly terminating the ISDN). There are both external and internal modems for BRI ISDN, with similar to the analogue (ISDN is digital) modem caveats. External modems use HAYES, https://en.wikipedia.org/wiki/Hayes_command_set#The_basic_Hayes_command_set command set (AT commands) and can do bonding at ISDN level so you get the 128 kbps as advertised when using both B channels. I've successfully did a number of deployments using Zyxel external modems which could be bought in stores as CPE (Client Premises Equipment) just as the other modems but at a considerably higher cost. The nice part of the ISDN setup were that you could pick up the phone and the modem would go single channel auto as the D line for signalling handles these, and you can get a micro ISDN PBX setup with the 2 lines for up to 8 phone lines of the "cheapest" models.. There are also internal cards, Fritz! AVM is one notable brand of devices AVM (BRI ISDN PCI cards) https://en.wikipedia.org/wiki/AVM_GmbH#Products both hardware and software based sets (the soft WOULDN'T work) which were possible to get to work yet very unreliable. As for the PRI ISDN, I have done only a couple of deployments for considerably high costs (300 EU/mo) local fees + activation (2x) and it is terminated by the TELCO as E1 line 2048 kbps most typically as HDSL2E1 termination for PBX E1/PRI interfaces so this provided 30 incoming and outgoing concurrent digital phone lines. You'll probably never have the chance to use PRI these days as faster and newer less complicated (and expensive) subscriber lines do the last mile. The time frame this got obsoleted is 2005 here in the SE EU with the mass avail of inexpensive ADSL broadband for the general population all towns. The most looked after feature was the synchronous data line rates for BRI and the almost instantaneous dial (digital signalling) connection set up, which I was typically configuring as dial-on-demand (at the gateway PC).. In Germany (where I worked at the time) ISDN lines were also used as ADSL due to the reliable and fast operation (digital lines) and similar costs. As a closing line (pun intended) the ISDN is considered obsolete in 2018. Kind regards, Anton Lazarov
Re: ISDN Card /PRI Card support on OpenBSD
We all weren't deprived, I had both an ISDN terminal adapter and IDSL circuit at my house. Both were outrageously expensive, they provided by the company I was doing contract work for. They had dialup ISDN data connections, I was their test node if other folks reported problems.

It definitely took AT commands. It's possible you could turn up something on ebay or similar (actually I see one up on ebay right now selling for about a tenth of the nominal price I paid for one way back then), so it might be worth a try. > Now if you could get those to work using ppp, I have no clue.

I think Paul is very much on the right track here, given that the box you connect has a traditional serial port or is able to fake one via something like a USB-to-serial adapter. - Peter -- Peter N.

PRI = up to 30 B channels over an E1/T1 circuit). Would need more information about what the "legacy services" are before it's possible to make any kind of suggestion (but apart from some data services on BRI which might work with an async TA, it's not really going to involve OpenBSD in directly terminating the ISDN).

Re: ISDN Card /PRI Card support on OpenBSD
Hi Tom, With the answers you already got, I think it's obvious that the american continents were deprived of this fine technology .. their envy is showing ;) However, there's one possibility: There used to be external ISDN "modems" (not really modulating or demodulating anything, but that's what marketing people called them so people would understand what these were in the same sense as regular modems were). These would simply connect to your serial port and provide you with a dial up interface that you could use. With some AT commands, these could be made to connect to the internet (if I recall correctly, they could even emulate a real 'modem' for old-fashioned dial-up). Eicon was the brand, DIVA the model of one particular example I've actually had the "pleasure" of working with. You can still find references on the web. The web 1.0, that is. Now if you could get those to work using ppp, I have no clue. But I think it's your best bet if you want to use your ISDN connectivity on OpenBSD in 2018 (which you don't).
