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."

Discover a number of valuable VOIP Tips In Improving Voice Quality

Before we talk about VOIP tips in improving voice quality let us see what VOIP actually is. VOIP is Voice over Internet Protocol. It has changed the way people communicate, professionally and socially. Users world over have subscribed for the free services that are offered by firms like Vonage and Skype as they provide solutions that cost low for communication over long distances. People are now able to keep in touch with loved ones for free no matter where in the world they are with the help of devices that run on the internet. Businesses are benefited greatly by using the technology of VOIP as they can keep the costs of overhead to a minimum and also maintain a functional and reliable service at the same time.

Many CEOs have specially redesigned the operational strategies of their companies to include VOIP systems. This in turn has helped in reducing excess personnel, office space and of course the overheads mentioned earlier. But the implementation of VOIP has not always been successful due to unclear transmission and dropped calls resulting in headaches for businesses and private consumers alike. One of the VOIP tips in improving voice quality is that when the system of VOIP starts showing trouble with quality, do not make the mistake of tampering with the equipment or altering the settings without having any plan. The cause of voice quality problems could be many sources. That includes the ISP. VOIP systems carry digitized speech in call protocol packets. If these packets are to pass in the Internet from one point to the other, they will have to pass a series of hops or routers that are like gateways. Every router has a limit to the amount of data that it can allow to pass. This is called throughput. This throughput is determined by the CPU of the system, any errors and physical bandwidth.
