This document provides answers to frequently asked questions about the Cisco VSC3000 virtual switch controller. Q. I have heard a lot about the New World Cisco voice architecture. Using industry-standard commercial computing hardware, the Cisco VSC3000 is designed to bring to packet telephony the reliability, serviceability, and uptime found in today's narrowband switching platforms. A. Cisco VSC3000 has been designed to provide packet voice solutions focused on service provider applications. The Cisco VSC3000 provides support for many variants today and is programmable to support all variants.
Cisco provides worldwide compatibility and unmatched flexibility.
The first software release of Cisco VSC3000 supports the features in Tables 1 to 5. K, Service Node application partners enable services such as Network Announcement Server. The ITU standard for this protocol will be called H.248, which is not available today for commercial deployments, hence MGCP is the de facto standard. When a Cisco VSC3000 voice network's capacity grows beyond the limits of a single Cisco VSC3000 node, additional Cisco VSC3000 nodes can be deployed to handle the increased load. When this happens, the Cisco VSC3000s need to communicate with each other when setting up calls from gateways controlled by one Cisco VSC3000 to gateways controlled by another Cisco VSC3000.
