asterisk users - May 2005 - I call an USA MOBILE phone and it is registered as ENUM => failed

I was tracking down an error in  my dialplan, .. but at the end it 
showed, that I called a mobile phone in USA, which had a successfull 
ENUM lookup, ...

Could that be?

[trunkUSA]

; USA & Canada  long distance through trunk
;    for ENUM drop 9
