Hi, sorry for spamming again but I'm not being able to register to a SIP provider populating the uacreg table, I followed the steps of this guide: http://by-miconda.blogspot.com/2010/10/best-of-new-in-kamailio-310-10.html, but I don't see any change neither any REGISTER packet sent out to the sip provider, is something missing? How can I know if the values from the table are being loaded? What are the fields: "l_uuid"  and  "l_username" for?  Is for routing incoming calls? I would appreciate any kind of help. 
Regards,
