Hi to all,
I finally got to make my pa module SER to work but I found a strange
behaviour with METHOD Notify :(maybe this is just the way it works :-)).
When I tried to change my presence state from connected to busy, SER
notifies to which is suscribed but instead of sending a busy status, it send
a OPEN status. In fact any change on status presence is notified as OPEN.
Whe the user is disconnected then SER notifies with CLOSED. Does the pa
module workds like this?, if not, how cani configure my SER to make it send
the right state presence?.

Ths status would be CLOSED if the presentity is not connected.
I also include the ser.cfg that I am using. The ser version is cvs
"ser_0.10.99+cvs20050519"
By the way, anyone who wants to implement pa module in SER could take this
ser.cfg as example ;-))
Thanks in advance.
