Do the VG224's manage V.90/V.92 speeds? Jeff's setup falls into the usual trap other YouTubers do. Dialing a modem through an ATA or other device directly into another modem caps the speeds at V.34 (33600 baud)

From what I understand of telecom of that era. You want to effectively keep as much of the signal digital as possible. With (ideally) the only "analog" part remaining being the link between the customer modem and the PBX.

The VG224 being (effectively) 24 ATA's in a trenchcoat seems to meet that requirement. Though once installed you'd need to connect it to a PBX such as Asterisk. Then, as I understand it, "trunk" that as a T1 line into something that can digitally handle modem calls such as a Cisco AS5300.
