The document discusses Calcasieu Parish School System's transition from an aging phone system to a new VoIP phone system. It provides background on CPSB, describes the goals and planning process for the VoIP project, and offers recommendations for other organizations implementing VoIP systems. The project was fully funded through E-Rate and has resulted in cost savings of $330 per phone station compared to the previous system's $700 per station cost. Key lessons learned included keeping stakeholders informed, rolling out the new system in phases, and maintaining backup phone lines during the transition.
