[Asterisk-Users] Incomplete incoming fax using spandsp 0.0.2pre10

Hi,

I have successfully compiled spandsp 0.0.2pre10 with * 1.05 which can accept
inbound fax calls. However, all fax received are incomplete  (the first 10%
of an A4 page is fine, the remaining is either missing or garbled). I
suspect this is due to 'training error' (see below) which, according to
Steve Underwood's postings, cannot be resolved further. I wonder if it would
help to upgrade my test machine which uses Asus m/b + Celeron 2.4GHz cpu +
512MB Ram + 2 Clone X100P cards (MD3200 chipset based) + RH 7.3. Secondly,
will the use of a Digium card fix the problem?

Thank you for sharing your inputs.

Steve FH
