IP Telephony: Reliability You Can Count On
One of the fundamental design goals of the Internet was to achieve an unprecedented level of communications network resilience. As a result, packet-switched networks fundamentally enable fault tolerance, adaptive routing, and disaster recovery, so it is quite possible—and can be quite cost-effective—to build IP-based communications systems that are more reliable than circuit-switched PBX platforms. The key is to start with the right foundation. Read on.
