And if you are going to do anything with voice, you are mandated to connect to the ILEC’s interconnection points (also known as tandems) for exchanging local traffic (as well as negotiating a new interconnection agreement or opting into an existing one). You are also required to connect to all of your region’s 911 interconnection points (also known as public safety access points, abbreviated as PSAPs) which are distinctly different than the aforementioned interconnection points. Finally, if you have an outage over 30 minutes in the US, in most cases, you are required to report that to the FCC within 2 hours of the event, then submit a final post-mortem within 30 days. Voice is no joke.
