VoIP Penetration Testing

VoIP Communications services are in use by organization for everyday communication.

If VoIP (Voice over Internet Protocol) is vulnerable to publicly known or unknown vulnerability, then we can exploit it. VoIP assessment performed with different test cases according to the VoIP infrastructure gives security assurance to the organization.

Encryption services, then, have become an essential tool in the fight against online criminal behavior. Encryption ensures both personal and business assets remain secure and out of the hands of criminals. As we move away from analog systems and ISDN towards Voice Over IP systems, we’re going to see big changes in the way we manage data security.

Baseel assess the VoIP network penetration testing for identifying the VoIP network vulnerabilities after determining the scope of work and a detailed report prepared, which is including vulnerabilities details with the recommendation.


A holistic approach to perform penetration test that not only discovers security vulnerabilities, but also finding business logic vulnerabilities along with security checklists based on industry standards, including OWASP Top Ten, PCI Compliance, and NIST 800-53.
