By convention, the modem that starts - originates -

central mainframe were often originate only.
So, try making your modern modem send answer tones. I forget how to do
this using Hayes commands, but I know it's possible. Then try it.
ATA will tell the modem to go off-hook and emit a carrier (ie. answer an
incoming call).
