VoIP Security and Access Control
Security has always been an important issue when deploying an over-the-top service, and, because of that, some organizations remain apprehensive about embracing VoIP and Unified Communications. However, there are many ways to mitigate risk and ensure VoIP security.
Securing a VoIP network has different requirements from that of a data network. Because a VoIP network is moving voice and video traffic, you must balance ensuring security with maintaining quality of service. With a VoIP network, security must be addressed with a multi-layered approach. Each subsequent layer increases overall protection and continues to offer defense, even if another element or layer is breached.
Learn best practices for securing your VoIP solution.
Protect Your Solution with IP Phones
An often overlooked area for ensuring VoIP security is your choice of IP phones. Some desk phones include tools that can provide an additional layer of security for your VoIP deployment. Some of the features to look for when selecting IP phones include:
IP phones with VPN clients can ensure the security of remote workers when they connect to the main office phone system. This enables the phones to seamlessly connect to in-house VPN servers. The use of a VPN delivers better voice quality and protects your network without compromising firewall settings.
TLS and SRTP encryption ensures there is no way to “eavesdrop” on calls as they move between the IP phones and IP PBX.
Bring Your Own Device (BYOD) is a growing trend that allows emplPhones with a factory-imaged unique key provide additional VoIP security than provisioning by a MAC address alone. For example, if a hacker attempts to create a fraudulent call using only the MAC address, their attempt will fail because the provisioning system requires both the MAC address and the factory-imaged unique key.
