[OpenSER-Users] Presence, multiple status info handling

[Pascal Maugeri]

Hi

I use the <timestamp/> element (section 4.1.7 of RFC 3863) of <tuple/> to
detect the most recent tuple and ignore the outdated ones.

Problem, the <timestamp/> is an optional element and your clients may not
insert it when publishing. Do you control the client source code that
publishes the presence information ? If no we should find a way in openser
presence module to add this timestamp element for you. I add a quick look at
PRESENCE and PRESENCE_XML but I haven't find anything yet.

Regards,
Pascal
