Thanks for the replies. On the cause 41 I get a 503 which matches up.
Getting cause 63 back for the ones where I see SIP 500 Internal Server Failure which is default behavior. I guess I'm good then, just wish I wouldn't see 5xx level for mis-dials. Yes, the numbers are valid E164 formatted numbers for US which the provider wants to see in that format. I can't call these numbers from other sytems either so they are indeed bad, un-allocated numbers.
