Well, I am not sure why Google went with XMPP when the rest of the telecom and networking industry is gravitating towards IETF SIP as signaling protocol. There are so may overlaps in both of them in the sense that they use the same components such as SDP and ICE. Can anyone from Google or otherwise throw some more light on
- Why Google prefers XMPP over SIP
- In what areas XMPP is better that SIP
I am not stating that one is better than the other, but would like to understand the core differences and advantages.
Also with Google moving on with XMPP and other major vendors converging on SIP, where do you see the inter-operability issue heading towards?
