Testing VOIP services

Now, let's focus on testing VOIP-enabled services and see how we can check for various flaws that might affect the VOIP services.

VOIP fundamentals

VOIP is much less costly than traditional telephone services. VOIP provides much more flexibility than traditional services and offers various features, such as multiple extensions, caller ID services, logging, and recording each call that is made. Multiple companies have launched their PBX on IP-enabled phones.

Both the traditional and present telephone systems are vulnerable to interception through physical access, so if an attacker alters the connection of a phone line and attaches their transmitter, they can make and receive calls on the victim's device and enjoy internet and fax services.

However, in the case of VOIP services, we can compromise security without using the wires. Nevertheless, attacking VOIP services is a tedious task if you do not have basic knowledge of how it works. This...
