With a second modem, an Analog telephone adapter, and a free Google Voice account you could do it.  Might have to set the ATA to G.711 to properly pass modem signals.
Or you could set up an Asterix server and run your own private phone network.

I am surprised there doesn't seem to be an open source soft-modem that directly speaks SIP protocols, but there is a commercial one at https://www.vocal.com/voip/sip-software-modem/
