[Users] failover and presence/IM service

[jimmy way]

Hi Daniel-Constantin,

   So, that means if I want to make SIP/SIMPLE
working(providing presence/IM/file transfer service),
I need only pa module on server. And, can you tell me
when will you release stable version of pa module in
your sechedule?


Regards,
Jimway
