VOIP Penetration Testing

VOIP Penetration Testing

Cyber attacks pose numerous threats to VoIP telephone systems, such as the capture of inbound and outbound calls through network manipulation, recording or listening in on calls, gaining access to internal networks through the voice VLANS and use of the network to make outbound calls (toll fraud).

In order to facilitate correct operation of VoIP devices, VoIP systems often operate outside of normal network security controls. Xyone is able to assist you in securing your system’s SIP and H.323 endpoints  whilst providing peace of mind against toll fraud.

We will assess your network infrastructure, VoIP components and authentication methods, and their capability to prevent manipulation between your clients and VoIP server to determine the scope of your security, providing a detailed report and recommendations for remediating issues and vulnerabilities.


It is vital that our clients undertake a retest as part of their penetration test service. This is to ensure that all vulnerabilities have had the necessary controls applied and are no longer at risk of exploitation.

Retests are always clearly quoted within our proposal documentation and each retest scans all of the areas originally identified as risks in our original penetration test report. 

Vulnerability Assessment
