VPN & IP Telephony
As modern Voice over IP telephony (VoIP) transmits voice information as IP data, VPN connections can also be used for this purpose. The Virtual Private Network connection allows voice data to be securely transferred to a central telephone system.
VoIP changed the nature of communication, giving you the opportunity to talk to anyone, anywhere in the world, at lower costs and with far greater privacy than traditional phone services had ever offered.
Voice over Internet Protocol (VoIP) calls convert analog signals (sound) into digital signals that are sent over the internet. These signals can be encrypted at both ends, making it much harder for a third party to hear, track, or record what is said.
