Per: http://soft-switch.org/spandsp_faq/ar01s07.html FAXing with spandsp keeps giving me core dumps. Its crap, isn't it? Actually the crap in this case is probably libtiff. Versions 3.5.7 and 3.6.0 seem reliable. The FAX image handling in version 3.6.1 is broken. All the core dump problems I have investigated turned out to be due to a very old version of libtiff, or version 3.6.1. I am getting crashes of Asterisk on transmitting faxes (not receiving), and have libtiff-3.6.1-10 installed. Does anyone here have experience with spandsp's txFax? is libtiff 3.6.0 available somewhere somehow to try it out?

Not a thing. Really don't know who is doing what or if there is something else I am doing wrong. Not only is AAH 2.8 based on Centos 4.3, but Asterfax is being put on top of that and it uses spandsp.... I **think** I am the only one trying this to a SIP attached fax, rather than a zaptel attached fax. And it MIGHT have something to do with improper codec negotiation. I have to put ethereal on the line and dig there. Just not getting answers from either the AAH or Asterfax list. And nothing from soft-switch.org (source for spandsp and comment about libdiff)....

Boy, I wish that I had looked here earlier... At 06:35 PM 5/24/2006, William Suffill wrote:>After chatting with the author of SpanDSP he tends to suggest using >3.8.0 of libtiff.

I realize currently libtiff is 3.8.2 but results drasticly >vary.Where do I get an rpm for libtiff 3.8? And once I install this later version, will a yum update put it back to 3.6.1-10? If so how do I exclude libtiff (I know, man yum).
