Using 2 (or more) ATAs at one location

Couple of idea's...

1. If your ISP will give you two IP's, get your modem into bridge mode (if its not a bridge only modem). Put a switch behind the modem, and put one of your ATA's on a public IP, or even behind a second router (and forward ports). If you have an RT31P2 this is a no brainer. The ATA on your LAN would have the Port forwarding done for it for that IP..

2. Find an older computer or embedded device and install pfSense (or Monowall) and install the siproxd package (sip proxy). This also entails putting modem in bridge mode if its not already... but no port forwarding. Voipo's servers see the proxy as your ATA's. The proxy forwards to the correct device. I use this here and at the office with multiple devices on each with no issues.
