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.
