Branch Gateway services

VoIP services

Branch Gateway provides the VoIP following services:
• Up to four VoIP DSPs that provide voice services over IP data networks.
• Allows you to use various types of phones and trunks that do not directly support VoIP.
• Translates voice and signalling data between VoIP and the system used by phones and
trunks. Avaya media modules convert the voice path of traditional circuits, such as analog
trunk, T1/E1, and DCP, to a TDM bus inside Branch Gateway. The VoIP engine then converts
the voice path from the TDM bus to a compressed or uncompressed and packetized VoIP
over an Ethernet connection.
Branch Gateway provides VoIP services over LAN and WAN. G450 Branch Gateway supports up
to four VoIP DSP childboards. The maximum number of supported active channels is 320. All
channels can be bidirectional FAX, G.711 u/A, G.726A calls.
