Sorry, I did a poor job explaining that. That's basically correct, with the receiving end first and our originating end last in your diagram. For outgoing faxes only, this is the setup: Fax interface (LAN website, in short) -> Asterisk PBX -> DSL modem -> Internet -> nexVortex trunk -> [recipient] Incoming faxes are generally more reliable, but I still get small number of failures. I've mistakenly overestimated the incoming failure rate. Don't have clean statistics on that, though. > Unexplainable FAX call failures (i.e. not wrong numbers of other >obviously wrong things) should be well below 1%. On a dedicated DSL >line, if everything is set up properly you should be getting that kind >of rate.

All of these faxes are going out to unknown, external machines. I have no control over anything on their ends, and the hardware/connection is as variable as you could imagine. I'll definitely look into SpanDSP. FWIW, the dedicated DSL line is just a 6 Mbps up/768 Kbps down Internet connection that is solely used by our in-house PBX to connect to the trunk. >However I'd just suggest that you look at the business case for screwing >around with fax at all. Oh man, if only... I'd LOVE to just drop fax completely and use email instead.
