The RTP packets are encapsulated in UDP, IP, and Ethernet envelopes as shown in

Audio data is also encoded using different formatting protocols. The audio format

Cisco monitoring and recording software and hardware supports several audio data
formats, including G.711 (mulaw and alaw), G.729. These formatting protocols are
used to encode the audio data for transport over the network. Some formats, like
G.729, greatly compress the data so it can be transported over a network faster.
