Summary of services

Voice over IP (VoIP)

The Branch Gateway features a VoIP engine that provides voice services over IP data
networks. The Branch Gateway allows you to use many types of telephones and trunks that do
not directly support VoIP. The Branch Gateway translates voice and signalling data between
VoIP and the system used by the telephones and trunks, as follows: Avaya media modules
convert the voice path of traditional circuits such as analog trunk, T1/E1, and DCP to a TDM bus
inside the Branch Gateway. The VoIP engine then converts the voice path from the TDM bus to
a compressed or uncompressed and packetized VoIP on an Ethernet connection.
Both the G250 and the G350 provide VoIP services over the LAN and WAN. The G350 supports
the G.711 codec for up to 32 concurrent calls and the G.729 codec for up to 16 concurrent calls.
The G250-Analog and G250-BRI support both the G.711 and the G.729 codec, for a total of 10
concurrent calls. The G250-DCP and G250-DS1 support both the G.711 and the G.729 codec,
for a total of 16 concurrent calls.
Physical media — G350
This section describes the various types of telephones and lines supported by the G350 and the
access ports provided for their connection.

Telephones

The G350 supports IP telephones, Avaya DCP telephones, analog telephones, and BRI
telephones. For information about which Avaya telephones are supported, see
B: Supported Avaya
Telephones must be connected to the correct type of port for the telephone type. Different types
of telephone ports are provided by different media modules and by fixed ports on the G350 front
panel. The table below lists which ports you can use to connect each type of telephone. See
