Good news the Cisco Spark and Cisco Jabber interoperability is up and running and working.   People using Jabber 11.9+ can now see and chat with people on Cisco Spark, but one to one only.   Soon spark spaces will also be supported.  There is some presence sharing between the platforms.

The Jabber Platform does not support access to Spark Spaces, ad-hoc group chats, the share of attachments or screen sharing across platforms at this time.  So 1 to 1 chat is all users get for now.   Details of new features in this link.

A few deployment requirements….

Jabber must be CLOUD DEPLOYED – so no on premise deployments are currently supported.  You will need to contact Cisco to get your system added to the Cisco Spark platform identity service.

This is a long time coming feature many clients have been asking for as customer embrace both platforms, however, most clients looking to migrate are probably using an on site implementation of Jabber today.  Hopefully, Cisco will support on premise migration strategies soon.
