    An LOA or Letter of Authorization is a document that allows your phone/VoIP vendor to request your numbers on your behalf.  The LOA also allows your vendor to talk to your provider to help with service issues, contract questions or porting.  The LOA is filled out and signed by the person that is Authorized on your carrier account and then given to your phone/VoIP provider.

    You will need a broadband Internet connection such as DSL, Cable or others (T1, Wireless, etc.).
