So you are looking for a winner of the Instant Messaging protocol debate are you?  Well, keep looking and maybe it will become clear over the coming years because XMPP has just gained another supporter, Yahoo. See this article on...

Graham Francis http://www.thesipschool.com Yahoo. See this article on CNET.  We think this is good for interoperability between other XMPP based services as no translation services would be needed - so Google Talk (also based on XMPP) should 'in theory' interoprate with whatever Yahoo do.  So far so good.

But what about SIP/SIMPLE?  Well the IMPP working group came up with a Spec/Set of rules/whatever you want to call it (the CPP actually) that defines how IM protocols should map to each other so that 'islands' of IM systems don't have to stay as islands and SIP/SIMPLE / XMPP systems can interoperate - just see what Jabber are up to to clarify this.

So is SIP/SIMPLE doomed because Yahoo and Google may end up on each others buddy list?  Well no, due to the fact that every Telecoms manufacturer I can think of (Mitel, Siemens, Nortel, Panasonic, Avaya etc. etc.) all use this protocol in their Unified Comms/Messaging products and are unlikely to switch.

So for now, no winners just two big players who should play nicely together (Hopefully).]]>
