Title: RE: [Asterisk-Users] SoftFAX/spandsp - rxfax findings (spandsp-0.0.1i)

Hi,

One more step ahead, with:
- no problems receiving from the regular fax machines in the office,
- 3 attempts receiving from J2: 2 successes, 1 failure (page cutoff),
- 3 attempts receiving from Dialogic VFX/40ESC: 1 success, 2 failures
        (page cutoffs).

Will share the txfax findings in a separate email.


Page cutoff (page 2) with J2:
