For endpoints that access your VoIP system remotely, the best practice is to provide access via VPN. This gives remote users what is effectively a private tunnel to the system which is encrypted so that the traffic cannot be intercepted by an attacker.

IP phones connected to internal networks need consideration too. The key issue here is the use of the phone’s Ethernet port. This is something that most IP phones mexico telegram have in order to allow a PC to connect to the network using a single port. For security and reliability, it’s important that this is properly configured at the switch so that multiple devices are allowed to access the same port.

If you are concerned about the risks arising from mixing voice and data traffic on the same network, you might want to consider setting up separate virtual networks (VLANs) to logically segregate the traffic.

VLANs are not, of course, immune to attack, but by separating voice and data traffic you reduce the risk. As always, it’s crucial to keep your security software and the software of any network switch equipment up to date to reduce the risk of zero-day attacks.

VoIP communications are increasingly a part of enterprises today and so their importance cannot be underestimated. In terms of keeping them secure, the information security team needs to make sure that it works with both VoIP users and management.

No system is perfectly secure, whether PSTN, mobile networks or VoIP systems, all require consideration and careful security planning. However, because VoIP systems are essentially network and computer-based, they allow for significant improvements to be made to security. Using VoIP allows for the addition of security enhancements, including better authentication, together with encryption of communication traffic. All of these can help to minimise the risks of using IP-based voice systems.

As with any technology, there will always be some level of security risk with VoIP. However, businesses that put in place proper VoIP security measures can achieve a higher level of voice communication security than is possible with older systems.
