Grandstream makes a number of gateways. I prefer a PCI(e) card though. I have a GXW4104 and I am about to trade it out for a 4 port FXO card from Sangoma. We are partners with both companies, so I thought I'd try to save a bit of money with the gateway. Well, I ordered a A20001D from Sangoma on Monday because of the problems I've been having with the gateway.
