REsource LOcation And Discovery (RELOAD) [RFC6940] specifies a peer- to-peer (P2P) signaling protocol for general use on the Internet. This document defines a SIP Usage of RELOAD that allows SIP [RFC3261] user agents (UAs) to establish peer-to-peer SIP (or SIPS) sessions without the requirement for a permanent proxy or registration servers, e.g., a fully distributed telephony service. This service transparently supports SIP addressing including telephone numbers. In such a network, the RELOAD overlay itself performs the registration and rendezvous functions ordinarily associated with such servers.

A SIP Usage for REsource LOcation And Discovery (RELOAD)
This document defines a SIP Usage for REsource LOcation And Discovery (RELOAD). The SIP Usage provides the functionality of a SIP proxy or registrar in a fully distributed system and includes a lookup service for Address of Records (AORs) stored in the overlay. It also defines Globally Routable User Agent URIs (GRUUs) that allow the registrations to map an AOR to a specific node reachable through the overlay. After such initial contact of a Peer, the RELOAD AppAttach method is used to establish a direct connection between nodes through which SIP messages are exchanged.
