[Asterisk-Users] Alternatives to SpanDSP??

[Matthew Boehm]

Damn. I'm using spandsp0.0.2pre15 and asterisk 1.0.7 with a single span card
(US PRI) and I can get it to work about 85% of the time on a single 1 paged
fax. I count a failed fax if any of the tiff images don't look like the
original.

I tried sending thru a 15 page fax. All 15 pages were received in the tiff
image, but every 2 or 3 pages, it would seem as if the image skipped an
inch. So instead of being 8.5 x 11, it was 8.5 x 10 (or 9).
