[Asterisk-Users] Software FAX

[Steve Underwood]

I am taking note of people's messages about soft fax, even if I might 
appear to be ignoring them. I am getting V.27ter finished off right now, 
to flesh out the facilities in the software. V.27ter is used for 4800bps 
and 2400bps faxes - not critically important, but useless for lousy 
lines. That's seems to be nearly functional now, so I should soon be 
back to fixing things.

Most of the crashes seem to be where people have an older version of 
libtiff. In each case I've followed up on they have a nice new libtiff, 
but still had an old version too. Older versions seem to cause trouble. 
I don't intend to find out why, since newer versions are OK.

An 8 byte TIFF file means it has been opened, and a header written. The 
basic TIFF header is always 8 bytes.

Regards,
Steve
