Branch Gateway provides the following VoIP services:
Up to two VoIP DSPs that provide voice services over IP data networks.
Use various types of phones and trunks that do not directly support VoIP.
Translates voice and signaling 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 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.
