That's the standard used in VoIP. Asterisk systems can use a protocol called IAX between them, but it's not something you see in an ATA very often. > > I see a SIP phone is connected between the router and the computer, like > my ATA. Why would it, but not my ATA, let me pull up my modem with Safari? To use a SIP phone, you would get a small hub and "split" the ethernet connection. Some SIP phones have built in hubs, so that when you added your phone, you did not have to run a second ethernet cable. For example, I have several 2000 vintage Cisco "IP phones" that have it. I don't use them (the internal hub). If you did use the internal hub, the SIP phone would use 1 IP address and pass data through it to your computer. It would NOT intercept it like the ATA.
