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?
