Make voice Network more secure

Security, VoIP - Voice over IP
We mentioned earlier all different attacks that can be focused to our VoIP network. Now is the time to see how we can apply different protection methods to avoid VoIP quality mitigation that can be started by all those attacks.
Separating voice traffic from data traffic with voice VLANs or by use of VPNs and firewall to protect voice traffic can easily prevent basically all most common attacks. One more thing that is important and often ignored is the security of voice endpoints and servers that can be increased with some simple configuration changes.
