Software architecture for telephony
Telephony Feature Processing is based on the existing Meridian 1 Call
Processing software and provides industry-leading feature capabilities.
The Virtual Connection Manager allows IP-based devices that are registered
with the Call Server to access the same feature capabilities as existing
telephony devices. In this way, the Meridian 1 feature set is made available
to evolving IP devices and soft clients, and is the switching foundation of
CS 1000S. In addition to access to the Telephony Feature Processing of a Call
Server, devices can also access other services in the network, such as XML
and IM. The Virtual Connection Manager supports IP Phones and a wider
suite of devices and services.
