I just purchased an Ojo Personal Video Phone PVP900 for my office. I have DSL hooked to a Netopia Cayman 3300 Series ADSL Gateway (which I'm told is a modem/router combo, even though it only has one Ethernet port). From there, I go to a Belkin F5D5231-4 4-port Router. And then, to the Ojo Video Phone. (I also go from the Belkin Router to a D-Link EBR2310 Router and then to my computer, which works fine.)
The Ojo staff called me as a test, but calls drop after about 10 seconds.
The tech people at Ojo said it's because I'm going through 2 routers and they're "getting confused". They told me to call my Internet Service Provider [Toadnet] and have them put the Netopia into "bridge mode". Toadnet claims that my modem is already in bridge mode (and they gave me the Username and Password) and now the Ojo people are stumped.
Any ideas ?
