Voice and multimedia networking
Intelligent networking and call routing
With Avaya Communication Manager, servers can use IP trunks across an IP network to
communicate between switches without the need for dedicated leased lines. With
Communication Manager, IP trunks can use Distributed Communication Services (DCS+) or
QSIG Services to extend feature transparency, centralized voice mail, centralized attendant
service, call center applications, and enhanced call routing across IP trunks.
