Legacy Phone World – Variety of Positives
Reliable
h Built on reliable OS, typically VxWorks
h No moving parts, outside of fan
h 7-11 year realistic life-span
h Each site remotely survivable
Workhorses
h Phones had strong functionality

Legacy Phone World – Host of Negatives
Each site is a silo unrelated to other sites
Applications are expensive additions
h Unified messaging, desktop call control, ACD, etc.
Management is per system, per site and usually outsourcedh Each new site multiplies the amount of management time
h 3 PBXs, 3 VMs and 3 ACDs to manage
Feature disparity between sites
h Reporting, phone portability, ACD applications, paging, etc.

VoIP Solves Many Legacy TDM Issues
Applications are easy to add and can be shared
Management is administered via a GUI or web interface
Features are transparent between sites with centralizedintelligence
Components for an IP telephony systems are consistent

Legacy Strengths Become VoIP Weaknesses
Centralized server with spinning media MTBF is lessthan 5 years (only some on real time OS)
Centralized brains make remote survivability a
substantive concern
Limited intelligence in the gateway is sometimes anoption
True remote survivability requires a call processor ineach site
