Hi Carlo,
Here are my ideas about this.
One solution would be to insert into usr_preferences table a record with
the URI where the call must be forwarded for the user (you can put the
username in RURI) when the presence status is "meeting", "holiday", etc.
And delete it when changes into something else.
Now the question is where to do this. In the OpenSIPS script is very
hard - you have to make regexps to extract the status from the Publish
body, select from database the previous stored state and apply the
regexp again, very inefficient. The other solutions are an external
application or an opensips module. The external application could query
the presentity table periodically or maybe be called by a trigger at
insert ( not sure this is possible). The module can export a function to
be called before handle_publish to analyze the previous and the current
state.
Then when handling Invites - do avp_db_load for the caller and if a
record is found forward it to that URI.

Dear all,
I'm thinking about a design of an unified communication system based
on presence status.
I would like to know if the presence status of a subscriber could be
used to define the routing logic.
An example is routing the call to voicemail when Alice's status is
"meeting" or to a cell phone when she is on "holiday".
Thanks,
Carlo
