Hi, I just started my very first attempt receiving faxes by asterisk. Compiling, installing and setup went without problems. (asterisk-1.0.7, libtiff-3.6.1, SuSE-Linux 9.1) When receiving a fax also everthings seems to work fine, but the tiff file itsself is corrupted. Various tiff viewers do report errors (wrong line lengths) and finaly display a picture, which has nothing to do with the original. Did anyone encounter the same problem? Is it a version problem of libtiff? (libtiff-3.6.1 seems to be the most recent one, besides CVS.) Thanks for any hints! Roger.

They keep breaking the FAX support in libtiff. 3.6.1 is broken, although a lot of distributions contain a patched version which works - usually because a spandsp user got the patch pushed into the distribution. HylaFAX users seemed to just give up trying to follow the buggy path of libtiff, and stick with libtiff 3.5.7 which seems to work reliably.

I had to search a while in order to find the "old" libtiff 3.5.7, which now works fine in my asterisk installation. For those being in the need of libtiff 3.5.7: Pay attention to my subsequent email!
