[Asterisk-Users] Softfax/spandsp

[Alex Zarubin]

Hi,

We've tried J2 faxing with the newest release of spandsp and found
the same issue as with our own Dialogic based faxing.

Steve, we can fax to your system from our platform and/or J2 if you
think it can help.

Here is what we see on incoming fax from J2:

Hi all,

It seems this week's release of spandsp fixed the major problems in the 
previous release, but still people have had a lot of trouble...
