Hi, 
I'm very grateful. The server is starting right now without any problems. It works fine with the following configuration. I hope it could help someone else. 
----------------------------- 
### XCAP 
loadmodule "xcap.so" 
modparam("xcap", "db_url", 
        "mysql://opensips:opensipsrw@localhost/opensips") # CUSTOMIZE ME 
modparam("xcap", "integrated_xcap_server", 1) 
#### PRESENCE modules 
loadmodule "presence.so" 
loadmodule "presence_xml.so" 
modparam("presence", "db_url", 
        "mysql://opensips:opensipsrw@localhost/opensips") # CUSTOMIZE ME 
modparam("presence_xml", "force_active", 1) 
modparam("presence", "server_address", "sip:x.x.x.x:5065") # CUSTOMIZE ME 
----------------------------- 
Regards,
