Security
Security remains a major ongoing issue for VoIP and, indeed, all internet-based technologies. The fact that VoIP ‘packets’ are essentially data means that there are all the same associated risks as with, for example, internet banking, albeit the data is less important and is less likely to be used fraudulently. With a number of VoIP providers offering apps to allow the system to be accessed from mobiles/laptops/tablets, it is even more important to find ways of ensuring company telephony systems and networks are protected.

Other security concerns include cayman islands whatsapp number data Spam over Internet Technology (SPIT) which just like spam emails is made up of unsolicited, often auto-generated messages. Some SPIT calls will attempt to get you to divulge personal or financial information and because there is no ‘subject’ line as with emails, you don’t know the call is SPIT until you actually answer it. This makes it harder to block/prevent. Some VoIP providers offer blocking features where they filter the call as it arrives before allowing it through if it is regarded as genuine.

Because VoIP systems are accessible from anywhere with an internet connection and from multiple devices, this makes them vulnerable to hackers, who have numerous ways of trying to attack you. To protect against hackers you should ensure that all passwords and PINs are changed so they are not set at their defaults, protect your network with a WPA protocol, keep all software up-to-date, scan regularly for viruses and be very careful when downloading anything.
