The Vocia VoIP-1 Telephone Paging Interface acts as a SIP end point allowing a direct connection to an existing VoIP call manager. The interface permits live, real-time paging using any page code within a Vocia system. When calling into a VoIP line, a number of software-configurable voice-prompt functions are available including page code selection, zone status indication, and page-now indication. A DTMF sequence of tones can also be programmed in the software to be associated with a Vocia control input event. The VoIP-1 supports Vocia regular and emergency messaging, and will also support page stacking and store-and-forward functionality.
