Call Accounting “What has been outstanding about the ETM system is the support, flexibility, simplicity, and control of the entire network. Its been a great tool and has been reliable. Support for Telecenter, our previous software, was not good. The application, though very robust, was too complicated and had too many problems. It relied on multiple modem lines to get the SSR's polling data, devices would stop polling when it reached capacity, and it required someone to constantly dial into the system to check if all of the collection devices were operating properly. In general, the old system was too complicated, with too little support, and offered no automated way to pull in data.” - Donna Pearson, Call Accounting Administrator
