[OpenSER-Users] Presence, multiple status info handling

[Dan-Cristian Bogos]

Hi Pascal,

many thanks for the tip. Looks like a nice approach on a first glance.

I use sip-communicator and am in contact with the developers. Will try the
approach for the client then, but the idea with the timestamp on the server
side could help much more people hitting the same issues and not able to
touch their clients.

Wish you a nice weekend!
