[asterisk-users] Fax from FXS to PRI

[Adam Moffett]

If I have a 4 port Digium FXS card and a single port PRI card on the 
same asterisk box, is it expected that I'd be able to plug a fax machine 
into the analog FXS port and have no problems sending or receiving 
faxes?  Our connection to the Telco is on the PRI obviously.

I don't recall the specific card models that we have, but I can check if 
it matters.

Does the version of asterisk or Zaptel matter?

My related question is this: In the scenario described above does the 
audio pass directly from one card to the other through the PCI bus or 
does it have to somehow be processed by software?
