LNP (Local Number Portability) rules apply to interconnected VoIP providers just like they do to conventional wireline and wireless telecom carriers

If you need proof that VoIP is becoming mainstream, just look to the Federal Communications Commission (FCC). The agency issued an order on October 31 stating that LNP (Local Number Portability) rules apply to interconnected VoIP providers just like they do to conventional wireline and wireless telecom carriers. The commission also took steps to make sure that number porting in general goes more smoothly that it has in the past. The combined moves make clear that, from a services standpoint, the FCC sees VoIP as just another phone business.

VoIP 將漸漸邁向主流通訊
如果你想知道VoIP會不會是主流通訊你只需要從FCC對VoIP的處理便可以知道.FCC於10/31開始將LNP(區域可攜式電話號碼)應用在VoIP上,也就是說VoIP不只可以得到電話號碼,更可以和有線或手機電話號碼換機換服務商不換號.委員會也會去管理以便號碼轉換很順利.從此可以知道FCC認為VoIP就和手機或有線電話一樣的通訊產業.
