Recently it has become increasingly clear that VoIP services will be expected to provide Lawful Intercept and Emergency Call Handling services to the same level experienced in the PSTN. The FCC in North America for example has mandated that both emergency calls and Lawful Intercept must be available. Whilst not all countries mandate this capability, any network operator building a publicly available voice or multimedia over IP service today will need to plan a network which is flexible enough to implement these regulatory services in the future. Session border controllers are being deployed at strategic points within VoIP networks to execute a number of access, security and quality management roles; they offer an ideal location to implement a Lawful Intercept solution. Carrier class SBCs already offer the levels of redundancy and resilience to provide 'five 9s' availability, further endorsing their suitability for the location of the IIF.
