As a VoIP engineer, you must be prepared beforehand.
You must ensure that your calls are secured end to end and protected
against malicious attacks, from eavesdropping to phishing.
It's important to prioritize security and reliability to
protect sensitive information during calls.
Let us discuss some of the best practices to keep in mind.
Keep your calls confidential by encrypting the signaling and audio using
secure protocols into coded data that can only be decrypted using the
correct keys. Divide your network into smaller secure segments to reduce
the risk of a successful attack. Distributing network VLAN into two, one
for voice traffic and the other for data traffic helps secure VoIP calls.
Firewall and access control lists are also used to control access to your
network and prevent unauthorized users from accessing the VoIP system.
Session border controllers also protect the network.
These devices are placed at the border to control access and defend against
any security threats. Stay ahead of security threats by conducting regular security audits and installing updates promptly.
