Michael Robertson Unveils SIPphone
JimCricket writes "After almost a year of preparation, the person behind MP3.com and Lindows has unveiled his latest venture: SIPphone. According to a CNET article, the new company sells VoIP-based telephones. I wonder what kind of latency you get with these devices." Interestingly, the CNET article reveals the telephones "...can only call other phones that use the same technology."
This business model seems very much like the way we as consumers should be heading.
I am reminded of the failed business plan when faw machines were first commercial (before they were common) FedEx offered a service called ZapMail, whereby they offered 2 hour delivery of documents rather than 1 day. They did this by faxing the documents around FedEx offices.
Of course people realised that for a small initial investment (buy a fax machine) they could do they same thing themselves, cheaper.
This seems a small venture at the moment and may be ulitmately unsuccessful due to the limitiation of only being able to call other SIPphones, but it is a step in the right direction and may pave the way for other businesses to operate using a similar model.
I see uses for not only businesses but for travellers and ex-patriots. It is increasingly easy and cheap too access broadband internet while costs of international phone calls are still high.
SIP is an IETF standard for voip, surely he just meant it could only phone other SIP phones! no need for any conspiracy theories! SIP is an open standard, and you can even get linux software linphone to use it... Just need a gateway to the traditional phone system and yer sorted.
SIP is not limited to just VoIP, as the name says it is Session Initiation Protocol. There already is a reasonable GNU SIP library, so let's make that better, and then we can create an open source SIP capable VoIP-phone that could interoperate with this system as well as others.
Other uses for SIP that could/should happen IMO are (starting a session of) multi-player games and messaging, conferencing software for sharing pictures, etc.
Since SIP is basically just a handshake protocol, doing all those things shouldn't be impossible. Wanna play a game of chess or go with a pal? Just initiate a SIP connection, if their end supports your game and they are available, you've got a connection. No more application specific ports to configure to get a multiuser application work.
As the name implies and the article explains, the phone uses SIP, or Session Initiation Protocol. I did some research on SIP last year and found it to be somewhat intruiging.
SIP is basically used for setting up the endpoints of a human communication channel over an IP-based network. It negotiates what kinds of communcations are supported on each end, and what protocols to use. So if a video-SIP-phone calls a regular analog phone via a SIP-PSTN proxy, the proxy would only support audio certain codecs. The calling video-SIP-phone and the proxy would negotiate to use only audio using a matching protocol and the cal would go through.
And since SIP is a protocol just like SMTP or HTTP, it is very controllable. There are dozens of SIP products popping up from SIP servers to SIP proxies... and now SIP phones. For example, you can have a SIP proxy/server be concious of where a user is logged in and re-route SIP calls to their present location. As a Java programmer, I'm looking forward to the day when I find a reason to write a SIP Servlet.
Furthermore, the latest version of Messenger in Windows XP supports SIP. I would think that this means a SIPPhone could call someone using Microsoft's Messenger on Windows XP. However, I was not able to confirm this with a breif perusal of the SIPPhone site, and they also state this only works with other SIPPhones. That may be an over-generalization to keep people from thinking it works with regular phones, or maybe they did something crazy with it.
I'm crossing my fingers that it is a generic SIP endpoint that can contact any SIP-enabled device.
