tmcnet - Encrypted VoIP over VPN Secures IP-Based Phone Systems

Voice over Internet Protocol (VoIP) systems are becoming exceedingly popular as they offer a host of benefits, including reliability, flexibility and substantial cost savings compared to traditional phone service.

Enterprises that deal with highly confidential information worry that transporting voice and data over an unencrypted public network can compromise the secure nature of their business.

Fortunately, VoIP-over-VPN can compensate for what standard VoIP fails to provide.

VoIP gateways with VoIP-over-VPN provide enterprises and carriers with a straightforward, reliable and highly secure way to transmit voice through an IP connection, while at the same time achieving the cost savings and flexibility associated with traditional VoIP.

Voice-over-IP and Virtual-Private-Network technologies are able to offer highly secure encryption by converting the voice into data packets, routing them securely through a VPN tunnel and then converting the digital voice back into an analog signal on the other end.

Patton (News – Alert) Electronics manufactures Smart Node VoIP-over-VPN technologies that feature IPSec 256-bit encryption for voice and data, DES/3DES & AES strong encryption keys and Internet Key Exchange (IKE) for automatic, dynamic keying. These systems protect all inter-office voice and data communications that are transmitted over the Web.

"By encrypting both voice and data, VoIP-over-VPN technology unlocks the cost-savings of Voice-over-IP for security-conscious enterprises," reads the white paper.

"By building voice encryption with IPsec and Internet Key Exchange (IKE) into Smart Node™ VoIP gateway routers, Patton makes cost-saving voice-and-data convergences viable options for enterprises that handle even the most highly sensitive information."
