Integration of voice into data networks is now become a reality.
VoIP stands for “Voice Over Internet Protocol,” and is an advanced technology that allows businesses and staff to communicate more effectively than is possible with traditional phone lines. This technology is also referred to as IP Telephony as it uses internet protocols to transmit packets of data.
Voice over IP refers to the transmission of voice traffic over internet-based networks instead of the traditional PSTN (Public Switched Telephone Network)
