Regular data backups are configured

As mentioned already, SIP trunks can be a weak security link for hacking since voice packets can be overtaken as they travel between two SIP endpoints. To protect that connection, look beyond the standard hashed password encryption. Some of the key measures to consider are as follows:

Verify that encryption is applied to both the voice portion of the communication and the SIP signaling and control packets. Limit the number of devices that can establish contact with your SIP trunk. Set a secure protocol and session validity that cover SIP port settings, SIP protocol inspection and termination, registration, and authentication methods. Implement privacy control mechanisms for all SIP trunk sessions. Properly configure SIP privacy headers, enable SIP normalization, protect against digit manipulation, and add extra encryption methods for the signaling and the media streams, such as TLS, IPSec tunnel, or VPNs on the IP connections. Regular Network Testing Last, but not least – conduct regular security audits and tests of your VoIP systems. We recommend using the SIPVicious OSS toolkit for SIP audits and the Viproy penetration testing kit, designed specifically for VoIP systems. Beyond that, you can also explore the newer generation of AI-based network security and monitoring solutions that are emerging on the market.

Being proactive when it comes to your network security pays off manifolds as you handle potential vulnerabilities in advance instead of throwing emergency resources into dealing with the complex (and costly) aftermath of compromised VoIP devices or part of your network.
