Branch Gateway Telephony Services - Avaya G450 Overview And Specification

• IPv6 supports stateless address configuration. IPv6 hosts can be configured automatically
when connected to a routed IPv6 network through ICMPv6. Stateful configuration using
DHCPv6 and static configuration are also available.
Deployment and transition
There are several mechanisms that simplify the deployment of IPv6 running alongside IPv4. The
key to the IPv6 transition is dual-stack hosts. Dual-stack hosts refer to the presence of two IP
software implementations in one operating system, one for IPv4 and one for IPv6. These dual-
stack hosts can run the protocols independently or as hybrids. Hybrid dual-stack hosts are
common on recent server operating systems and computers.
Tunelling allows to use IPv4 infrastructure to carry IPv6 packets when an IPv6 host or network
must use the existing IPv4 infrastructure. Tunneling can be either automatic or configured.
Configured tunneling is more suitable for large, well-administered networks.

Branch Gateway telephony services

Branch Gateway provides a telephone exchange service, supporting the connection of various
phone types and outside telephone lines. Phones and lines are connected to Branch Gateway
through media modules on the chassis. Different media modules provide access ports for different
phone types and lines.
Telephony services are controlled by a Media Gateway Controller (MGC) running Communication
Manager call processing software. You can use Communication Manager to configure advanced
telephone exchange features. For more information, see Administering Avaya Aura
Communication Manager.
