Suggestions on which ATA to buy

I need an ATA that has two ethernet ports, and one FXS port. The ethernet ports need to be set up as a switch. I do not want one that has a router built in unless it can be configured as a switch. I’m trying to avoid running any extra cable or setting up a standalone switch.

I’ve seen this but I’m not sure about the quality of the item. Has anyone had any experience with one? Any other suggestions?

using the x100p in a 300 employee office to handle calls relating to sick leave. works like a charm but it tends to hate other cards on my mother board (HP DX workstation).

Not the X100p. The S100-FX. What you’re referring to I think is the cheap FXO PCI card they sell. I’m interested in their ATA.
