The peer-to-peer layer effectively replaces the registration,

location, and lookup steps of SIP. It handles three things:

⻬ Registering a phone or a user with the peer-to-peer

overlay network (when the phone or user joins the

network)

⻬ Looking up a phone or a user in the peer-to-peer overlay

network (when a call to the phone or user is made)

⻬ Dynamically sharing information when peers join and

leave, so that the load is balanced across peers, and

so that the sudden loss of one or more peers doesn’t

cause the peer-to-peer network to lose track of its cur-

rent registrants

Figure 6-1 shows how this process works.
