Innovaphone does not support the known standard "CalDAV" protocol to synchronise the presence with any calendar software that supports "CalDAV".

The "CalDAV" is a protocol that make it possible to synchronise the calendar of any calendar service g.e: Exchange or Tobit with any 3rd party product that supports "CalDAV".

Is it possible that Innovaphone supports the calendar data exchange between "CalDAV" and its presence entities?
