WAN LAN ADSL/Cable ---------- VOIP_Box ----------- Router/Switch ------- Computer Modem | | +-------- Computer | | +--------- Computer RJ-11 RJ-11 +---------- Computer Phone Phone #1 #2 Some early VOIP boxes, liked to strip off the VOIP packets from the Ethernet, before hitting the Router/Switch. The reason for this has something to do with the port numbers used by VOIP. VOIP is a complicated protocol, with separate port numbers for Call Control and for Data Transport. If the VOIP box was put *after* a box with NAT (address translation), then punching holes (port forwarding) for the necessary ports becomes a painful thing. http://en.wikipedia.org/wiki/Voip Your "box with the phone jacks", might look like this. http://en.wikipedia.org/wiki/Image:VoIP_analog_telephone_adapter_diagram.png Paul |
