[Serdev] non terminal NAPTRs

ENUM +441414960913

The lookup should be continued on the second domain.

I am not sure is pure academically issue. The US carriers plan to split 
the ENUM space into info for carriers and users and they look at non 
terminal NAPTRs as a solution.  On the other hand it is discouraged by 
the best practices document  mainly because we can get looping 
situations.
