IMO, it's just an illusion of added security and is really just CYA for the provider. When I fax TWTelecom an LOA that a customer faxed to me, how does TWTelecom verify the authenticity of that LOA? I doubt they try. I suspect it's just filed, and will only be pulled out if the advertisement is challenged by some 3rd party.
