No, Jingle is not a Christmas promotion from Google, though it does involve a
“gift” from Google.
Jingle is a newly published specification for doing voice over Jabber’s
XMPP protocol, which the Google Talk IM client uses. Google Talk’s implementation of Jingle is now
also available for download and third-party integration via the Google
sponsored “Libjingle” project on SourceForge.

Google isn’t the only group that sees potential in Jabber’s Jingle, either.
The open source Asterisk IP-PBX project and its commercial overseer Digium is also set to support the
Jingle initiative.
“Jabber and Google recognized the need for a protocol to bring VoIP to
Jabber users, and as Asterisk is designed to work with a number of
protocols, we want to support all the interfaces we can,” Mark Spencer,
president of Digium and creator of Asterisk, told internetnews.com.
Asterisk brings an important set of features and a high level of
interoperability with existing PSTN and SIP infrastructures to Jabber
users.”
