✦ Synopsis

As the session initiation protocol (SIP) gets deployed, attention invariably needs to be paid to which SIP entities, user agents (UAs), proxies, back-to-back UAs (B2BUA), host services, and to what the impact is on the entity if the service causes it to fail. This paper discusses providing SIP services in terms of individual entities. We address how each of the entities participates in a SIP network and provides services in an individual capacity as well as part of the collective SIP network.
