You don't necessarily need the XCAP functionality. Only If you want to 
have privacy permission rules enables( and of course it you have clients 
that support this - eyebeam for example). And if you set the 
'force_active' parameter to 1 it means that you don't want this feature. 
See http://www.openser.org/docs/modules/1.3.x/presence_xml.html#AEN92
What version of openser are you using? If 1.3.x then some of the 
parameters from presence were removed. Look in the log file of openser ( 
syslog if you have not filtered it) and search for the first error when 
starting openser.
