Fax with an ATA?

Asterisk Asterisk Support
1

I have the following setup:

PSTN -> Asterisk -> SIP Phones

I want to add a fax machine to the mix. Can I just use an ATA in front of the FAX. Is there a special codec or mode I need to use. Faxing seems to be more art than science right now with Asterisk.

PSTN -> Asterisk -> ATA -> Fax Machine

Is there a certian ATA I should use?

Thanks,
Chris…

Must use G.711 (ulaw or alaw). Some report success in this.

I have a Fax machine connected to a Linksys PAP2T that is working well. My TDM400 card has now a FXS module but I didn’t try it yet. BTW, my fax is an old MinoltaFax 1800 with a 9600 modem. From what I’ve read, the new ones are more problematic.
I can’t send faxes using my VoIP provider, only using the PSTN line.

jackyu2324,

I visited you web site and could not find any information on the models you posted. Couple of questions:

Your ATA devices support:

  1. fax pass through
  2. with Asterisk (1.4?)
  3. using t.38 pass through mode

Do you have an english site with information on the models.

Thanks,
Chris…
