The one-X Portal for IP Office server includes an XMPP server as a component which is enabled by default. This server allows the users to IM each other and to share their IM presence.
Archiving of instant messages is also enabled by default, allowing you to search user's previous messages.
Prior to IP Office Release 9.1, each IP Office system had a default XMPP group that contained every IP Office user as a member. As a result, each user was able to automatically see other user's IM presence.
For IP Office Release 9.1 the above no longer applies. The sharing of IM/presence between users requires the manual configuration of XMPP groups containing those users in the IP Office system configuration (refer to the IP Office Manager help or documentation).
