We have openfire server version 3.7.1 and spark version 2.6.3. We would like to enable below feature on openfire or spark. Can you pls let us know if this possible via any plugin or any other way
Ability to video chat
Ability to white board with other users
Ability to access instant messaging from mobile devices (iPhone/Android devices)
There is no official solution for any of these requests.
On video chat you can check this part of the forums (http://community.igniterealtime.org/community/plugins/red5) and maybe you will find a solution. Keyword would be Red5. Though setup can be tricky. Check the documents and blogpost posted by Dele, he is the author of Red5 plugins and is working on video chat.
There is no mobile Spark version. There are many other xmpp/jabber mobile clients. You can try them, you can search the forums and find threads about various mobile clients.
