Anyhow, some of them may not accept calls from foreign networks so you
should check if you can interconnect. Prefix routing is your solution
and I guess each provider implements its own numbering and prefix
allocation policy - I have not heard about any standardization in this
direction.
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.

Hi guys,
I've made my first full operational SER Server, in fact there are
too server talking to each other. When the call is not to another SER
server, it forwards to another external server, when the requested
number belongs to my other SER Server it go there and close the voip
tunnel, just as usual. So, at the moment, I'm implementing my
routing logic, in order to implement it well, i need all the phone
ranges and their server names or IP to route all the calls to the
right server, for example, if a user calls a "1213..." begging phone
number, it goes to Go2Call, and so on the all other Phone numbers.
Do anybody know where can I find a list of phone number ranges all
over the world, I mean, every VoIP server has a certain range, without
it my calls will be lost, and they will not end where they were meant to.
Thanks in Advance.
