AFAIK, the FAX targets are normal FAX machines, on the PSTN.

What happens is, there appears to be a dial out, and a FAX negotiation, but it always fails.

I think what Bryan is asking: Where is your FAX source? If the sending system is coming in on another port on the TDM card then fine, if it's coming in via the Internet (SIP, IAX) then it's going to be variable at best...

Is your carrier delivering service via a TDM circuit?

It has been our experience that you will get far more reliable fax
performance via the method you describe (analog device terminated to
a port on a FXS line card) than attempting to use an ATA on the LAN.
However, if your carrier is a SIP or IAX trunking provider, your
reliability concerns are on the other side of your SIP switch.

There seem to have been many discussions about this, so sorry if
this is boring.

Can one connect a "standard" fax machine (or fax modem) to an
analog port on a TDM400p (as if it were an analog phone, say) and
expect it to work reliably?

For sending, that is.  Detecting and "routing" the call is another
subject (for me).

Seems it "should", but does not.  At least not for me.
