The routing protocol is ENUM, but only few service providers have ENUM 
entries for their number ranges. The problem is that most countries are 
still in a "trial" state. There are also private ENUM trees to benefit 
from ENUM without paying for the ENUM domains (like e164.info...)

IMO using prefixes is PITA. You need a prefix for every SIP domain 
(there will be thousands soon). User has to remember all the prefixes. 
That does not scale. This remembers the beginning of the Internet 
without DNS where you had to edit the hosts file of your PC.

Their are also other mechanisms (like Dundi for asterisk). But ENUM is 
the only method where the association between Internet phone numbers and 
  E.164 phone numbers is validated by a public authority.
