D-Link DVC-1000 Videophone Review

Posted by michael on from the transylvania-6-5000 dept.

Milton Linkle writes "One of the first H.323 compliant videophones, that doesn't require a PC, is slowly but surely making it's rounds. This review provides a very good overview of the product, and even includes a few video caps of the device in action. If this product, or others like it eventually take off, we may get to a point where we no longer have a need for traditional telephones."

  1. H.323 Blows by Hayzeus · · Score: 2, Informative
    At least as far as firewalls are concerned. Last I checked, H.323 SW/devices did IP and port negotiation within the protocol itself, making getting it thru firewalls a major PITA.

    At one time, someone was working on a Linux masq module to get h.323 to work with a linux box used as a firewall, although (again, last I checked) this didn't work too well. If you use a linksys or other "dsl/cable" router, you'll probably be SOL.

    they just bought linksys

    netgear and dlink are the two major 'low-end' vendors now

  3. One of the first? by Wesley+Felter · · Score: 2, Informative

    Companies like Polycom and Pictel have been making H.323 videophones for several years. Of course, they tend to be so expensive that I'm not surprised /.ers haven't heard of them.

  4. Re:SIP or H.323 ?? by kvigor · · Score: 2, Informative

    Actually, there are (at least) three. H.323 is the original ITU spec. It is shockingly complex and scales poorly, since it is incredibly chatty. It is, however, feature rich and is probably the most widely implemented standard, though vendor interoperability is spotty at best, due to the complexity of the protocol.

    SIP is a reaction to H.323. It has damn near zero features, but is efficient and easy to implement. This is number two with a bullet, and rising fast, despite its serious limitations.

    H.248 is the IETF's attempt to fix H.323. I don't know much about it except that it's allegedly much simpler than H.323 while being much more featureful than SIP. It's the cool new buzzword; it remains to be seen if anybody actually implements/uses it.
