Project Gizmo Challenges Skype

valmont writes "The Register is offering an interesting introduction to Project Gizmo, a new player in the Voice over IP field, poised to challenge Skype with its ability to interoperate with others thanks to the SIP protocol it complies to. Whereas Skype has selectively licensed usage of an API that offers limited insight into a closed protocol, a closed ecosystem solely controlled by one organization, the SIP protocol is open. Free open-source proxy/server implementations are sprouting up, and many developers are actively working on SIP clients. The Gizmo Project is the first to bring a truly-usable, user-friendly, cross-platform SIP client (Mac, Windows, Linux coming soon) to market. Meanwhile, theappleblog.com is already offering a Gizmo Project Wish-List to promote better interoperability between current and upcoming SIP providers, to make it more practical for users of disparate SIP clients to communicate with one another."

  1. Also see Ineen and P2P SIP by Wesley+Felter · · Score: 5, Informative

    Ineen is similar to Gizmo but it also has IM and video. It seems like companies are falling over themselves to give away SIP clients these days.

    Ineen and Gizmo are still client-server SIP systems, but to truly compete with Skype, the IETF is working on P2P extensions to SIP.

  2. Re:SIP and NAT by valmont · · Score: 5, Informative

    WRONG, NAT was SIP's weakness ONLY until the STUN protocol came out in 2003. Since then, all SIP clients use the STUN protocol to traverse NAT at least as well as Skype does. I've used EarthLink SIP, sipphone.com SIP, FWD through multiple layers of NATs without a glitch.

    STUN is a major enabler of SIP

  3. More about Gizmo by Anonymous Coward · · Score: 5, Informative

    Ok, we admit it's a lame name, but we think the product is solid. Here's why it's significant:

    - It is based on SIP so other SIP hardware and software should interoperate. Check out http://www.siphardware.com/ for some of the hardware devices. I have a Call-in-One so a SIP call rings my home phone. Even a wifi SIP phone should work with Gizmo.

    - It navigates firewalls and NATS. Skype has done this well, but SIP clients have generally not. Gizmo Project should penetrate just about any firewall or NAT setup. I used it successfully on Boeing's wifi service on flight to Frankfurt 2 weeks ago bouncing calls off satellites.

    - It's Mac/Win today and YES, there will be Linux client shortly. No, really.

    - We're committed to an open directory meaning that we will interconnect with everyone. We already connect to many big and small networks. See: http://sipphone.com/numbers/. We do enum lookups. We even support the intriguing DUNDI extension for Astericks. I want VOIP world to be like email where one address is reachable by everyone. I hope VOIP does NOT become like IM where AOL can't talk to MSN who can't talk to Y, etc. If you care to read more about why I think this is important, you can go to: http://michaelrobertson.com/.

    - All calls on IP network are free as is voicemail, call recording, conference calling, etc. (try calling 1-222-xxx-xxxx and create an instant conference call with unlimited number of callers.) Only have to pay if touching the PSTN. We do give you 25 cents for free to check out the PSTN quality.

    - Be nice because it's just beta software! Thx.

  4. Don't let anyone snooker you out of your freedom. by jbn-o · · Score: 5, Informative

    The license for Gizmo Project software is quite clear, the software doesn't even qualify for the weaker standard of "open source" (weaker than "free software" which requires that the user have permission to make private derivatives):

    License Restrictions

    You may not reproduce or distribute the Software for any purpose whatsoever. Without limiting the foregoing, you may not copy the Software to any server or location for reproduction or distribution. You may not reverse engineer, decompile or disassemble the Software. The restrictions contained herein apply equally to any updates that may be provided to you by SIPphone.

    The company offers what they call "Opensource support", which appears to be little more than name-dropping. But I expect people around here to know better than to take on faith whatever a proprietor says.

    At the very least, even if there is no intention to bamboozle users into adopting the software, this is yet another use of the term "Opensource" which shows how people don't understand what that term means. Reminiscent of examples of same from the FSF essay on the differences between the free software and open source movements (examples include Neal Stephenson's writing, the State of Kansas' definition, and a particularly interesting example from a trade show in late 1998).

    As a result of a little digging into Project Gizmo, I still see no real competition for GNOMEMeeting. I see one more proprietor asking me to install a mysterious program on my computer so that the proprietor can do something on my computer that I am prohibited from inspecting, sharing, or modifying.
