Code Blue Speakerphones may be connected to a Voice over Internet Protocol (VoIP) network using a gateway in the same manner as a fax machine, dial-up modem or any other single-pair, analog device. A gateway device connects to the network using a standard network cable via an RJ45 connection and the Code Blue speakerphone or public address system (PAS) connects to the gateway via an RJ11 connection.

The image below is a simple illustration using the MVP210 to connect two analog devices to the network (the number of analog devices that a single gateway can connect to the network is limited by the make and model of the gateway used).

Code Blue Corporation does not manufacture gateway devices. Therefore, Code Blue’s recommendation that the same company that supplies the standard hardware for the VoIP
system should supply the gateway device.
