Avaya G860 Media Gateway

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:

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.
