A VoIP stands for the voice over IP. The VoIP gateway is defined as a hardware device which is used to convert the telephony traffic into the packets of data that is used for transmission over the internet. It acts as the bridge and connects the VoIP with the worlds of the legacy telephony.
In a VoIP setup, the signals form the analog phone of the campus equipment are converted to the IP data which can travel over the analog telephone lines of the phone company.
