How to Improve VoIP Security

Switching to VoIP is an investment. It costs about $1,500 per employee to implement office-wide VoIP for a company with under 500 employees. It is necessary to implement measures that secure this investment. VoIP can save you on phone bills and comes with soft benefits like increased productivity and better internal

communications. But, like any new technology, there are still bumps that need to be ironed out.

For instance, your business VoIP needs to be monitored. VoIP monitoring ensures best performance. It guarantees that your business is always accessible to clients and members of your team. Dips in VoIP service performance can affect your profitability. When you know what going on, you can address issues or use the services of another VoIP service provider.

Another aspect of VoIP that needs to be considered is VoIP security. Like any data that travels digitally, VoIP voice and video packets can be intercepted and used maliciously. An unsecured VoIP network opens you up to call fraud, phishing and eavesdropping, among other attacks. When you fall victim to call fraud, your voice call identity can be used by the attacker. Your account is billed for the unwanted usage. In VoIP phishing, your account is spoofed to acquire information that can be used toward fraudulent ends. Eavesdropping, on the other hand, is good old-fashioned spying on your conversations. There’s absolutely no room for this in any business. In business, information is power.

Protecting your VoIP starts with choosing the right service provider. Remember that VoIP operates through protocols, such as Session Initiation Protocol (SIP) and Real-time Transport Protocol (RTP). Signals are text-based in SIP while RTP does not have enough security to keep packets from getting intercepted. The better alternative is to use VoIP service providers that utilize Transport Layer Security (TLS) for their SIP and Secure Real-time Transport Protocol (SRTP) instead of basic RTP.
