Avaya Communication Manager
Communication Manager IP capabilities and applications support voice over an IP network, and
ensure that remote workers have access to communication system features from their PCs.
Communication Manager also provides standards-based control between Media Servers and
Media Gateways, which allows the communications infrastructure to be distributed to the edge
of the network. The Communication Manager IP engine offers features that enable users to
increase the quality of voice communications. Quality of Service (QoS) features enable users to
optimize voice quality by assisting some routers in prioritizing audio traffic. Communication
Manager Media Processors allow for hairpinning and shuffling. These features make voice
communications more efficient by reducing both per-port costs and IP bandwidth usage. Avaya
IP Telephony Solutions support trunks, IP communications devices, IP Port Networks, and IP
control for Media Gateways. Avaya IP Telephony Solutions are implemented using various IP
Media Processor circuit packs inside the Avaya Media Gateways. The IP Media Processors
provide H.323 trunk connections, and H.323 voice processing for IP Telephones. H.323
signaling is handled by a C-LAN circuit pack or native processor Ethernet connectivity. The IP
network can be extended across geographically disparate locations. With Communication
Manager ISDN, Distributed Communication Services (DCS+), or QSIG services,
Communication Manager can extend feature transparency, centralized voice mail, centralized
attendant service, call center applications, and enhanced call routing across IP trunks.
For more information on Communication Manager architecture, see the
Call processing
chapter.
Media Gateways and Port Networks
Avaya Media Gateways support voice and signaling traffic that is routed between
circuit-switched networks and packet-switched networks. Avaya Media Gateways support all
the applications and the adjuncts that are supported by the Avaya DEFINITY® Enterprise
Communications Servers, accommodating Call Center and Customer Relationship
Management applications, messaging, remote workers, and remote offices. Avaya Media
Gateways work with standards-based IP networks, and connect easily with the Public Switched
Telephone Network (PSTN). The IP network infrastructure provides support for the
communication between the Media Servers and the Media Gateways.
In a Greenfield installation, the recommended gateways are the G350, G650, and the G700.
The G650 houses traditional circuit switch boards and boards that support IP Telephony. The
G700 and G350 house Avaya Media Modules that provide ports for non-IP endpoints, including
analog and DCP telephones.
