Did you know?

That Sametime and Office Communications Server interconnectivity is so very close but as usual separated by two interpretations of a standard?
The SIMPLE (SIP for Instant Messaging and Presence Leveraging Extensions) is the standard I am referring to. Microsoft have taken SIP, added some extensions and that is what they use server to server, whilst Sametime, having a proprietary protocol internally, has a gateway that talks IETF SIP, i.e. the basic, standards-defined SIP. Which means, in layman's terms, that the two systems cannot talk to one another.... without some kind of SIP router/gateway/translator in between.
The good news is that I have heard it rumoured that IBM/Lotus may be releasing a module for their gateway pretty soon that talks Microsoft SIMPLE and thus interconnectivity would take one step forwards.
