The 3.6.1 release problem with G3/G4 is a given. And then there was the 16-to-32 bit type change that occurred with the 3.4.x-to-3.5.x change. In all the years of using HylaFAX I've never had any other libtiff issues give me any grief with HylaFAX. In fairness, however, HylaFAX only uses a very narrow set of functions and utilities from libtiff. It has its own G3/G4 encoder and decoder built-in and relies on that most of the time. Lee. It doesn't matter what facilities you use. If you get libtiff to open a bad TIFF file, it may well dump core. TIFF has been one of the most abused standards over the years. It used to be that hardly any FAX software would read the TIFFs produced by another package - both because they were too stupid to read perfectly good TIFFs, and because many of the TIFFs were not good.

I think this was while he was at Pixar, ... but at any rate libtiff was (and still is) very robust, and very unlikely to dump core at a moment's notice. Sam retired from the project and there have been a few quality control issues since then (very specific and limited in scope), but it's still fairly actively maintained and still 'good code' IMHO. TIFF and standards are not entirely synonymous, I agree. Blame Adobe, keepers of that spec for not disseminating it effectively. That's just politics though ... libtiff's stability is not linked to that. Have you reported the stability problems you're seeing to the libtiff crew?

Steve has already made it clear that he sees no future in fax, and that he does not intend to bridge that feature-set gap at all. I'd like to amplify that, and make at least one serious comment on this thread. First of all, the fact that fax isn't rocket science has led all manner of goofballs to engineer devices that take great liberty with the standards, ... and that fail in all sorts of weird and wonderful ways. The low barrier to entry, combined with the ubiquity of fax technology, means that any _industrial_ fax application needs an extremely robust T.30 engine at its core if it's going to be taken seriously. There's just SO MUCH CRAP to contend with out there. Fact: fax is easy to do poorly, and difficult to do extremely well I know what you're going to say ... my $75 toshiba fax machine does it well, it can't be hard! That may be true, but consider how many people, how much RD and how much intellectual property is tied up in their fax T.30 engine, and you can see there's a reason desktop fax machines generally fax much more reliably than, for instance, faxmodems (which are generally crap). Spandsp's rxfax and txfax could one day be suitable for mission-critical use (even if they _do_ have the capability to take down asterisk), but today they're not quite there. I certainly would not base a business on this technology. It's a very cool tool for hobbyists right now .. .a classroom exercise on how to do faxing from first principles and a way to illustrate the power of a much more generally useful technology, namely spandsp itself which is, quite simply, awe inspiring. As Lee has highlighted, the author does not plan to flesh out the fax implementation. If our customers were to implement spandsp many of them would be facing monthly phone bills that are _thousands_ of dollars higher than what they're presently paying thanks to the superior feature set in dedicated Eicon and Brooktrout fax boards, or even in HylaFAX's own Class 1 implementation. Anyone who has studied the economics of faxing will know that the up-front cost generally pales in comparison to the ongoing cost of telco charges and administrative headaches if lots of faxes are failing. Sure, HylaFAX itself if a wonderful platform for mission-critical or enterprise faxing. It also has a very robust scheduler which is highly configurable, that scales well (we routinely send batches of a half-million faxes with no problems at all), and it generally does everything you could ever want a fax system to do, with the lots of hooks for anything more ... eccentric. But features and functionality are only worth something if you need them, and as some people have rightly pointed out, some people don't need anything more than fax reception, PDF conversion, and mailing. To those people who then conclude spandsp is the right way to go, I say you're missing the point - you need to look much deeper into the heart of the matter. How good are txfax and rxfax at coping with real-world fax freakishness? Personally, I think it's a shame spandsp's author doesn't think fax is sexy like we do. -The Undertaker -- Darren Nickerson Senior Sales Support Engineer iFax Solutions, Inc. www.ifax.com [EMAIL PROTECTED] +1.215.438.4638 +1.215.243.8335 (fax) ___ 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

If my choices are between HylaFAX and spandsp and if I want outbound queueing and a client-server interface for networked usage, then spandsp will not cut it alone. So yes, anyone who wants these features will need to use HylaFAX. And to use HylaFAX with Asterisk currently one must send the fax calls to an FXS port and then to a HylaFAX-controlled modem. Theoretically chan_capi could also be modified for fax support, since that is already part of the CAPI specs. But spanDSP works for all channel types so i dont see the need for this. Anyhow capi4hylafax and chan_capi will gladly coexist. You just tell asterisk to ignore the DIDs that are used for fax. [snip] Oh, and btw, i receive all my faxes with capi4hylafax and HylaFAX of course, just because SuSE comes with such a nice configruation tool for it (and i am lazy!). :) Wouldn't have thought otherwise.

Steve has already made it clear that he sees no future in fax, and that he does not intend to bridge that feature-set gap at all. Unless someone does something serious about the flakiness of libtiff, I don't think either spandsp or Hylafax will ever be very stable. :-( I said I see FAX as a dwindling market that will gradually drift away. I never said it was not significant right now. I really want spandsp to offer people a cheap way to fulfill this fairly long term, but not very high profile, need. So, show me a T.38 channel driver for Asterisk. And if you think that using t38modem is ugly, then show me a T.38 driver for HylaFAX. I really want to see spandsp talking through T.38 across the internet. T.38 and fax to/from e-mail were my main goals is writing spandsp.

How can we help you get there? If we can get spandsp talking T.38 then we can use t38modem, and you wouldn't really have any pressure to work on flaky fax any more as everyone could just use HylaFAX.
