Important new FCC rules (2009 & 2010) mandate that LNP include VoIP providers. This ruling states numbers must be able to be ported both in and out of VoIP providers. Further, these FCC mandates require interconnected VoIP providers to follow LNP guidelines and not impede a customers right to port their numbers in many cases, allowing them to port numbers, which until these new rules, they might not have been able to. Even if your VoIP provider is not a CLEC, which many are not, this does not release them from falling under the FCC LNP mandate, as they are interconnected (Interconnected VoIP providers would be providers whose services allow either inbound or outbound calls to the traditional PSTN telephone network.). The exception would be a VoIP provider who only allows calls to other VoIP customers and does not connect with traditional telephone customers.
