A longer video demonstrating several modem dial-up calls over VoIP, even a unexpected bonus working V.90/56k connection!
Prior to making this I wouldn't have thought even a V.90 handshake was possible, but it indeed worked a least for a little bit before it dropped. Calling out to a local ISP I got carrier speeds ranging from 50,666-53,333 bps.
Originally in the first video I was testing modems over VoIP so people could actually dial in to a retro bulletin board system (BBS) I was working on, but it got cut short.
