Nothing has changed. The issue wasn't with ATAs themselves, but VoIP providers. They handle things like compression that are out of your control and can mess with the modem signaling. Without a VoIP provider, you can configure everything so that the modems will be able to connect at 33.6kbps. As the article mentions, 56kbps requires special equipment on the ISP's end which is why 33.6kbps is the limit.
- tjohns 3y agoThe big problem isn't compression - that can at least be disabled (in theory). Modems expect a circuit-switched network which guarantees zero packet loss and zero jitter. Even if you connect using G.711 μ-law (uncompressed), you're still using a packet-switched network subject to packet loss and jitter. There's just no way around that. In that regard nothing has changed. This setup is inherently unreliable. You can do it for fun, but trying to get it to work outside of a lab environment is never going to be production quality.
