This module serves as a storage engine for PCSCF contacts, much like the standard Kamailio module, usrloc, is a storage engine for standard SIP contacts. The concept of a contact in IMS, PCSCF specifically, is very different to that of std. SIP and as a result we have built this new module. A lot of the design has been borrowed from the std. usrloc module. For example. An IMS contact, in PCSCF, needs things like: * Diameter Rx session for signalling bearer status. i.e. this is effectively QoS from the network to make sure the signalling link can be 'trusted' * IPSEC Security Association for secure signalling between UE and PCSCF (first point of contact) * IMPU, each contact can have a number of associated public identities (IMPU).
