VoIP peering continues to take the world by storm as it allows service providers and enterprises to interconnect VoIP networks directly without the need to have calls from one VoIP network to another travel over the PSTN. Using the PSTN to transmit calls that originate and terminate via VoIP is like printing an e-mail between the sender and recipient, then retyping it back into the computer and sending it off to its destination. Benefits of peering? Less cost via fees and taxes, less regulation, better quality and being a part of what will eventually be the defacto way we transmit VoIP calls between disparate networks.
