A dial peer is a
static routing table mapping phone numbers to interfaces or IP addresses
A call leg is a
logical connection between two routers or between a router and a VoIP endpoint.
A dial peer is associated or matched to each call leg according to attributes
that define a packet switched network, like destination address.
peers are matched to call legs based on configured parameters, after which an
outbound dial peer is provisioned to an external component using the
component's IP address. For more information, refer to
Dial Peer Configuration Guide.
In CUBE, dial peers
can also be classified as LAN dial peers and WAN dial peers based on the
connecting entity that CUBE sends or receives calls from.
