The Mastercall Dial-up PA Interface, with an inbuilt line-powered pre-amplifier, interfaces a standard telephone line, analog PABX extension, VoIP FXS or ATA port or TIPT IAD port to a line-level input of a Public Address amplifier. It allows people to make PA announcements from any telephone simply by dialing the PA extension number. The MD-4900 has an inbuilt microprocessor controlled busy tone and disconnect tone detector so that calls to the PA disconnect virtually the moment the caller hangs up.
