Ported numbers are ported in as ELS except in rare cases. As an example, Level3 won't issue ELS numbers (or port them) in areas where they don't provide E911 (based on service address).

Since we do E911 separately and don't use their service for that, we have seen some cases where we had 911 coverage but Level3 did not and did those as LI.

99% of the time ported will be ELS anyway.
