Hello everyone,
When having multiple presence sources for a same SIP uri (e.g. different
devices or when mix_dialog_presence is enabled), OpenSIPS puts the
newest one on top. Consequently, most softphones display the most up to
date information first.
However, I wonder what is the exact behavior : does it change on
presence refresh through PUBLISH requests, or only when a new and
different XML body is published for a given tuple ?
For example, imagine the following generic behavior :
1) At 10am, I publish a PIDF document with a given tuple. It is valid
for 5 minutes.
2) At 10:04am, I publish another PIDF document with another tuple for
the same presence URI. It is valid for 5 minutes.
3) At 10:05am, the first PUBLISH is refreshed for another 5 minutes.
What will be the topmost state in the PIDF ? The one published at 10am
and lastly refreshed, or the one published at 10:04am ?
If this last one is not refreshed, I suppose it switches back to the
10am published state. Am I right ?
Thank you,
Damien Sandras
