Today’s phone systems give you great flexibility and many features. Some of these are intercom, distinctive ring sounds for differing phone lines, the ability to have a particular phone line ring in one or several locations, door phone, and unlocking a door remotely by pressing a button on the phone. Voicemail can also be included, generally it requires an additional module to be purchased with the phone system. We sell and service Panasonic, and Vodavi phone systems.
