Since the introduction of VoIP, the service or underlying technology (based on the SIP protocol) has been susceptible to multiple fraud scenarios. In particular, by exploiting some of the features of VoIP, such as three way call and call transfer, hackers can inject call signals into the network and effectively hijack calls. The result is significant non-billable revenue for the Service Provider. Since commands associated with VoIP technology are often sent un-encrypted and without authorization for each command, this is an easy technique to carry out.
For both fixed and mobile service providers, maximizing the effective use of network capacity is becoming key to increasing revenues and assuring the quality of experience for customers.
In one recent test Empirix was involved with, callers were complaining about long connection times and poor voice quality during a storm. The company involved conducted a test of its SBC to better understand the origin of the issue. During the test process, the organization discovered that, while having a registration flood of 10,000 concurrent SIP registrations, SIP call setup time doubled. Moreover, jitter increased on the SBC.
