In this session Dustin will explain how Maquoketa Schools transitioned from an antiquated VOIP solution, Cudatel, to a cloud hosted 3CX installation. He will explain how they were able to integrate their existing paging system into the new system along with how they were able to add web based paging to not only use the new phones for telephone calls but also for PA access and also for bells. He will explain how to integrate their legacy paging amp/door access intercoms into this technology as well. This session will focus on the technology involved in making this transition along with the benefits of moving from a legacy bell system that was not synchronized with a NTP server to now having accurate bells. He will also touch on their implementation of ultra atomic clocks regarding how this increased time accuracy in buildings while reducing the cost of maintaining an antiquated clock system. https://docs.google.com/presentation/d/1M8Xq2Ha22e-wtiTO6FXHzmvuKHRAo7vz5eeg8XgCCRU/edit?usp=sharing
