Are you saying you dialed one of your own numbers with a Vumber to determine where the Vumber call would show as originating from? To see what the caller ID showed? Which "true" cell phone number was revealed? The one you were calling or the one you were calling from? Was this a potential glitch in Vumber's normal processes or was it the result of a third party tampering with the programming? I'm more than a little confused here, thanks for clarifying!
