In this scenario, master paging stations or workstations act as paging sources, independent of any central system. A PBX phone system can still be integrated as a paging source via the SIP protocol. A master paging station essentially supports better audio quality and voice intelligibility than a traditional PBX phone system-potentially making a difference in emergency situations.
Value adds like background music, SIP communication, priority paging, PoE and reduced infrastructure, such as integrating the traditional standalone amplifier into the decoder or speaker at the end point, are all possibilities when moving your paging and public address operation to the IP environment.
