Avaya G860 Media Gateway
Issue 6 January 2008 151
Example configuration for call center
The Avaya G860 Media Gateway allows call center customers to consolidate facilities and
reduce communications costs. The media gateway concentrates incoming PSTN traffic over
several DS3 lines while supporting VoIP telephony in the call center itself.
The use of voice over IP (VoIP) and conversion from DS1 to DS3 lines eliminate the large
number of DS1 interfaces required to support the same amount of call traffic. The Avaya G860
Media Gateway supports up to 6000 channels of SIP VoIP telephony. It uses N+1 redundancy
of media gateway, Ethernet switch, shelf controller, and power supply modules to achieve high
availability in mission critical applications.
In the sample call center configuration shown in Figure 59
, a simulated PSTN delivers customer
calls using a DS3 interface to the Avaya G860 Media Gateway. The media gateway establishes
calls with the Avaya S8720 or S8730 Server via SIP signaling and routes all Real-time
Transport Protocol (RTP) traffic to the appropriate media resources within the Avaya G650
Media Gateway or Avaya endpoints. Avaya Communication Manager delivers the calls to an
agent phone.

Agents can also make outbound calls using the same network. In the sample configuration,
multiple TN799DP C-LAN circuit packs support alternate routing and permit load sharing of calls
delivered by the Avaya G860 Media Gateway.
Note:
Note: SES can be part of this configuration. The G860 communicates to
Communication Manager over the LAN and SES is not needed between the
G860 and Communication Manager for the G860 applications.
