Recommendation on USB Channel Banks?

I’m looking to simulate T1 and analog lines into my labs. Currently there is a server with PCI cards but I had come across USB Channel Banks that seem like it could replace needing actual cards.

Has anyone used Astribanks USB Channel Bank or something similar? Looks like there is only one option and has been branded a couple different names … nnel-banks

I wanted to also see if I could use this in a virtualized server with ESXi but that might be a different story.

Hi Yes we have used Xorcom units, for pots and isdn lines, But I wouldnt use them in a virtualised environment.

on VM deployments we use either sangoma gateways or Digium Gateways.
