SPIT cyber security is the practice of defending your VoIP network from spam, malware, phishing and other malicious practices. Voice traffic firewall software is a great example of effective SPIT cyber security because it screens potentially harmful caller IDs and restricts their access to your VoIP network.
Call encryption is another way to make your online conversations safer. If a VoIP provider you are considering doesn’t offer call encryption, start looking elsewhere. That's why choosing a secure VoIP provider is half the battle.
However, if you have concerns about internet telephony, Brosix’s voice chat messaging app is a great alternative to using VoIP altogether, precisely because of its security features.
