Review on Enhanced Grandstream Gigabit NAT Router featuring Power-Packed 2-Port ATA by Anne Battle

Works exactly as advertised. First update the firmware if it is not already installed. Take your time with the web interface and make sure you set passwords for both access levels. You really only need to enter the SIP proxy IP address, password/authentication information and outgoing caller ID information. Works great with many SIP ITSP providers. You can program two lines as different SIP accounts, different incoming phone numbers. wouldn't put it directly on the internet, the firewall isn't that good.
