With the rapid evolution and growth of VoIP, it is no surprise that we face some security threats today. But it is important to take them seriously and protect your VoIP system.

Some of the most common risks today are:

1. Denial of Service (DoS) – Attacks on a network or device that overwhelm the server and cause loss of service. The attacker may be attempting to gain remote control of the system.

2. Eavesdropping – Hackers may be able to listen in on VoIP calls to steal information.

3. Spamming – We have all dealt with spam before and VoIP is no exception. Spam over IP Telephony (SPIT) sends spam messages to your VoIP phone.

4. Theft of Service – Attackers can gain access to your VoIP solution and use it free of cost. This uses up your resources and may slow down the system for paying users.

The first step is recognizing and understanding the risks. The next step is to prevention. Download our free VoIP Security whitepaper to learn more about how to protect your VoIP system: www.bicomsystems.com/voip_security
