/**
 * This class to a given registration.
 * The registration is added in the pbx UI by the admin or user. This registration can be either a uri whose the hostname is a ipaddress:port string
 * or a hostname of the form mobicents.org by example. In the former case, it will be used directly, in the latter case, a set of registrations
 * location will be maintained and populated by the RegistrarService.
 * Example for the latter case, for a REGISTER with a From: sip:jean@mobicents.org header and a Contact: sip:jean@127.0.0.1:5060 headers
 * The registration is the URI of the FROM header and the RegistrationLocation is the URI of the Contact Header without the parameters
