[Asterisk-Users] Alternatives to SpanDSP??

[Craig Guy]

I agree with Steve on this, am piloting Spandsp 0.0.2pre15 on asterisk 1.0.7
with a TE405p, euroisdn.  Fedora Core 2, kernel 2.6.9.  Running on an old
Dell Optiplex desktop PIII 450mhz with 256mb ram.  Takes on average 350
faxes / day with just under 1% failed faxes.  I define a failed fax as one
with a filesize of 8bytes or won't render to pdf.  On the strength of the
pilot I am planning to install it to production at another site that takes
approx 800 faxes per day.
