I work for a hospital with 22 remote clinics/sites. We currently have a Seimens Rolm 9751 telephone system in place at the hospital and a mixture of Rolm, Inter-tel, Nortel, and Samsung systems at the other locations. There are approximately 2000 digital and analog phone ports used at the hospital. We are going to replace the aging Rolm system this year. We'd like to network the larger remote sites together for transparency and centralized voicemail. What do other hospitals use for their telecommunications needs? What systems are easier to administer? Thanks!
