Hi,
We have terminals outside and need to update the configurations via PSTN. Users need to operate the terminal and it will dial up and build PPP connection to our server.
That means we need to setup a PPP server by using Windows server 2019 equipped with modem/FAX cards to accept incoming calls.
I have inserted 2 modem cards on the server and setup with inbound capability in the Port Section of Remote routing access on both of them.
Only one modem card showed up in the Port and the other modem card is missing which means only one card can take incoming call.
I need to enable both of the modem cards to accept different incoming calls.
I can't find any solution since this is a really really old technolgy (V.34 PSTN modem).
Thanks.
