Virtual private network (VPN) is a technology that hides a system’s IP and encrypts all communication of data during the use of the internet. The technology is already in use by many from private to professionals to experience secure browsing sessions and unblock websites. VPN channelizes the flow of data through a secure network prohibiting malicious attackers to intervene and get hands on it. Apart from secure browsing, VPN has found grounds in VoIP services as well. The primary aid is that it allows users to access VoIP services in blocked countries as well with complete security from being tracked.
However, it is also utilized to carry out traffic in VoIP. It is possible to use VPNs as a line for VoIP in a business network, but some specific requirements must be met to make traffic in VoIP work. Understanding the ability to reduce latency and quality of service (QoS) are two basic ones that minimize the tendencies of undesirable network disturbances, service drops, and unreliable connections.
QoS is necessary for voice traffic to have adequate bandwidth to function, without which there might occur network congestion, interruption in voice calls, and degradation in call service. In such a scenario, having a VPN for QoS will extend relations to other ends of the line as well. QoS will help in avoiding jitters that occur either because of packet latency or disturbance in the order resulting in a bad experience. However, there exist several specialized VPNs that address the issue adequately and maintain high QoS for voice traffic to function.
Furthermore, VPN has several other benefits as well in VoIP.
• Enhanced Security: If one operates over internet security is always a significant concern. Similar to browsing sessions ISPs can monitor VoIP traffic, hackers can lay ears on voice calls. Therefore, using VPN encrypts the VoIP traffic prohibit it from surveillance.
• Avoids Bandwidth Throttling: When VoIP calls stretch for long hours, it might happen ISPs start to throttle bandwidth as it consumes too much data. A VPN restricts the ISPs to keep an eye on data traffic and allows long calls without bandwidth throttling.
• Cost Effective: International calls are often high priced, and VoIP is the best option to connect with relations. So in areas where data rates and telecom rates are high or where VoIP service is blocked VPN serves as a cost-effective option.
