[OpenSER-Users] Presence, multiple status info handling

[Dan-Cristian Bogos]

Guys,

while dealing with presence/presence_xml modules, I came into one situation
when one user crashes simultaneously and each time displaying different
presence info (online, away, offline). Have noticed that the presence server
is smart enough to inform all the other watchers about three different
status information for the same user.

My question is, how can the watcher know the most recent status information.
Have looked on both order of info in the tuple as well as on ids but did not
find any logic. Can u please guide me about possibilities I have?

Thank you in advance,
DanB

PS: FYI, I am pasting such a tuple example.

<tuple xmlns="urn:ietf:params:xml:ns:pidf" id="t9062">
    <status xmlns="urn:ietf:params:xml:ns:pidf">
    <basic>closed</basic>
     </status>
</tuple>
<dm:person xmlns:dm="urn:ietf:params:xml:ns:pidf:data-model"
xmlns:rpid="urn:ietf:params:xml:ns:pidf:rpid"
id="p8838"><rpid:activities/></dm:person>
<tuple xmlns="urn:ietf:params:xml:ns:pidf" id="t5358">
<status><basic>open</basic></status><contact>sip:user at domain.com<sip%3Auser at domain.com>
</contact><note>Online</note>
</tuple>
<dm:person xmlns:dm="urn:ietf:params:xml:ns:pidf:data-model"
xmlns:rpid="urn:ietf:params:xml:ns:pidf:rpid"
id="p4226"><rpid:activities><rpid:away/></rpid:activities></dm:person>
<tuple xmlns="urn:ietf:params:xml:ns:pidf" id="t7139">
<status><basic>open</basic></status><contact>sip:user at domain.com<sip%3Auser at domain.com>
</contact><note>Away</note>
</tuple>
<dm:person xmlns:dm="urn:ietf:params:xml:ns:pidf:data-model"
xmlns:rpid="urn:ietf:params:xml:ns:pidf:rpid"
id="p4606"><rpid:activities/></dm:person>
<tuple xmlns="urn:ietf:params:xml:ns:pidf" id="t5632">
<status><basic>open</basic></status><contact>sip:user at domain.com<sip%3Auser at domain.com>
</contact><note>Online</note>
</tuple></presence>
