The integration will effectively allow Jabber users to launch WebEx meeting from Jabber’s instant messaging clients.

Denver, Colorado-based Jabber says the integration will be complete by the third quarter this year.

Jabber’s Extensible Communication Platform (XCP) is built on the IEFTF-approved XMPP (extensible messaging and presence protocol) instant messaging standard. The company claims there are ten million users of XMPP worldwide today.

San Jose, California-based WebEx is a market leader in Web conferencing software.

Both companies are eyeing lucrative joint and cross-sell opportunities in the near-term.
