Peer-to-peer audio is a core feature of all Lync Server deployments, and is very simple to configure and support, since it doesn’t involve integration with any other systems. Much like IM, P2P audio involves a point-to-point conversation between Lync endpoints; however, in this case the network communications include audio codecs rather than simple text. This audio communication requires more bandwidth than IM and is also much more sensitive to network latency. However, P2P audio still generally requires relatively little in the way of system resources. Because P2P audio communications traverse the data network only, generally good quality can be expected even across a wide area network (WAN) or the Internet.
