[Asterisk-Users] SpanDSP RxFax receives junk - gets Fax3Decode2d: Warning, (FakeInput): .... messages

Tue Aug 17 12:50:02 MST 2004

I'm trying to install the RxFax in Asterisk.  After much trouble getting app_rxfax.c (and friends) compiles and installed into Asterisk (thanks to the many asterisk-users messages) it did get it installed.  I have been unable to receive a legible fax.  app_rxfax provides lots of debugging information but none useful to me.  I was hoping that someone has an idea what might be going on.

Asterisk version: Asterisk CVS-HEAD-08/12/04 ... on a i686 Linux (RedHat 9 2.4.20-31.9smp)
PC is a Tyan with P4 3.06Ghz hyperthreading
The spandsp is a recent download from 8/12/2004
I'm testing with a T1-PRI only (no analog cards), sending a fax from an HO d135 all-in-one and tried a second Brothers "dumb" fax with the same results.

Everything was compiled today and the non-fax asterisk is running just fine.

Here's what appears to be a problem: Fax3Decode2D: Warning, (FakeInput): Line length mismatch at scanline 0 (got 3198, expected 1728).

Any help would be nice.

Here's the console log for the fax receive:
