What type of communication is established for Level III VoIP service between two computers?

Level III VoIP service typically operates using a peer-to-peer communication model. In this context, when two computers are involved in VoIP communication, they can exchange data directly with one another without the need for a centralized server to relay the messages.

This architecture allows for more efficient data transfer since each computer can connect to the other directly, reducing latency and potential bottlenecks that are common in client-server models. Moreover, peer-to-peer communication is advantageous in VoIP applications because it enables seamless interaction for voice data, enhancing call quality and providing a more resilient connection, particularly in scenarios with fluctuating network conditions.

In contrast, client-server communication involves a central server handling requests and responses between clients, which can introduce unnecessary delays in real-time communications like those in VoIP. Broadcast communication sends data packets to all devices on a network without targeting specific receivers, making it inefficient for one-to-one voice communication. Multicast communication allows data to be sent to multiple designated recipients but is still less direct than true peer-to-peer communication between two computers. Thus, peer-to-peer is the ideal method for Level III VoIP service between two endpoints.
