which program use SIP i known only linphone ( very little use )

2 & 3
the simplest one
an other idea is to use the jabber protocol ,opensource server & client code 
are available

use a plugin system to manage registering mode
seconix old mode
ldap new mode
FREEWORLDIALUP sip mode
jabber mode

in all case the most important thing is the period of "status refreshment"

for that reason the status refresh message in this protocol must be very light

user profile can  be removed from this message
