[Asterisk-Users] fax receive using TDM400P

[Anton Krall]

Guys.

Ive been testing how to receive faxes using TDM400P cards and so far, after
playing with gains, echocancell and echotraining on zapata.conf.. Ive ha dno
luck, faxes come in as garbage or broken or with blank lines.

Anybody has successfully done this? Any tips.. Also I have some ideas:

1. Is it really possible to get fxes on a fax machine using ATAs like the
sipura 2002? Even using ulaw and pass-thru, is it possible?

2. Since the faxes is coming from PSTN thru the card, I guess asterisk will
always stay in the middle right? No way around this.

3. Im also trying to receive faxes usign a TE110P card with spandsp, unicall
and E1 R2MFC, no luck also, some stuff, garbage and broken faxes. Anybody
done this sucessfuly?

Hope anybody can share their thoughts and insight on this.
