5.1.3. Dial Peer

The key to understanding our voice implementation is to understand the use of
dial peers. Dial peers describe the entities to and/or from which a call is
established. All of the voice technologies use dial peers to define the
characteristics associated with a call leg. A call leg is a discrete segment of a
call connection that lies between two points in the connection, as shown in
Figure 5-1
the perspective of the source Gateway as shown in
the perspective of the destination Gateway, as shown in
dial peers to Apply specific attributes to call legs and to identify call origin and
destination. Attributes Applied to a call leg include Quality of Service (QoS),
compression/decompression (CODEC), Voice Activation Detection (VAD), and
fax rate.
