The interfaces for delivering fax that I know about are: 1. Modem tones embedded in acoustic/bearer path; 2. T.38 (to gateway with TDM or analog PSTN trunks). Is there another method I don't know about? On April 27, 2017 7:35:42 PM EDT, Colton Conor <colton.conor at gmail.com> wrote:
I am pretty sure all these carriers just use HTTPS Faxback technology. I know Concord Fax provides wholesale fax service to Momentum Telecom. All that I have seen require an Audiocodes HTTPS fax adapter. Not sure what runs the server piece. Is there anything opensouce that supports HTTPS fax? No, I am not talking about SIP or T.38 that shit doesn't work well.

Fax is dead. Long live fax.
We've resisted supporting it, but customers still need it on occasion, and they hate having a separate landline carrier just for a fax line. So I'm wondering what others here use successfully to provide their customers with a "fax line" to a physical machine. We would only use a handful of them, and only with our customers who have a fully managed service (IE, 2-3ms connection directly to us over MPLS). We run Asterisk and pass T.38 to a few carriers. We currently do fax to e-mail inbound on Asterisk with no issues.
Volume is very light, maybe 3-5 per day per customer, so things like the Vitelity FaxEnable don't make economic sense ($25/mo unlimited our cost).
