Is VoIP Secure?

Prevent costly hacks to your VoIP system.

Like any form of new technology, loopholes in voice over IP (VoIP) phone systems can be exploited by hackers. It is important for business owners and network administrators to take precautions to prevent potentially devastating security breaches.

A costly problem occurs when criminals hack into a VoIP system and place calls. IT staff should utilize access lists on gateways and regularly install patches to gateway software. Firewalls and intrusion detection systems can also be implemented.

Spammers can also exploit VoIP voicemail systems to send messages to thousands of IP addresses at once. Choosing stronger passwords on voicemail accounts and changing them often can help prevent this type of scam.

On many networks, VoIP traffic travels over the same network as corporate data. Eavesdropping can occur by listening to the data packets. To protect private company data, companies can set up a separate virtual local area network (VLAN) or use a virtual private network (VPN) to provide a secure tunnel for voice traffic.

Finally, ensure your phone company uses a redundant and secure network to provide your VoIP service.
