IP Telephony: Reliability You Can Count On
sponsored by ShoreTel

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.

Today's IP-based telephony solutions fall into three basic categories:

  • Systems evolved from traditional PBX platforms
  • Systems evolved from traditional data-switch platforms
  • Systems designed from the ground up for IP-based communications
Read this paper to learn how these architectures help deliver highly available IP telephony systems.
