The system of choice for large-scale
enterprise business communications
and call center applications
The Avaya G650 Media Gateway delivers the scalability, features, and system uptime that enterprises
require for mission-critical telephony applications in campus and large office environments. The G650
seamlessly integrates traditional circuit-switched and IP-based telephony networks, providing core
telephony gateway services to all endpoints in a mixed TDM/IP environment, including:
•
Tone Generation and Detection
•
Call Classification
• Protocol
Translation
• Audio
Processing
•
Voice Codec Compression and Transcoding
•
Announcement Storage and Playback
•
Audio Mixing for Call Conferencing
Designed to address the need for converged solutions, the Avaya G650 Media Gateway gives
enterprises flexibility to adapt to changing business needs and allows them to evolve easily from
circuit-based telephony infrastructures to the next generation of IP infrastructures, including those
based on the open SIP (Session Initiation Protocol) standard.
Avaya solutions are based on a modular architecture of centralized media servers that provide call
processing and control through Avaya Communication Manager and a distributed network of media
gateways. For call control, the G650 Gateway connects to an external Avaya S8500 or S8700 Media
Server over an IP link. This enables the enterprise to design and administer telephony services for all
gateways from one central location.
The G650 is complemented by the TN2312BP IP Server Interface (IPSI) circuit pack, which adds
Emergency Transfer, environmental maintenance, and duplicated call control features in the gateway.
For scalability, up to five G650 Media Gateways can be combined to form a high-capacity port net-
work that may be integrated into existing telephony networks, supporting voice connectivity over IP,
TDM, or ATM transport. A single IPSI may be used to provide server connectivity for the entire port
network. For mission-critical applications, port networks with two or more G650 gateways can
support duplicated IPSI circuit packs that provide fully redundant control paths to the Media Server,
ensuring call preservation and operational continuity in the event of path failure within the network.
