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.
There is a list with some VoIP service providers, but for sure it is not complete: http://www.voip-info.org/wiki-VOIP+Service+Providers
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.

wont the 6 digit (or whatever ) numbers that most voip providers have internally soon be disbanded, for the "normal" pstn number range, and with e164 interconnect these will be routable of voip anyhow.

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.

That will be sometime in future, if ever -- depending on who and how is going to control it -- there are VoIP communities across many countries and would be rather complicated/expensive for the provider to buy numbers from each country. Anyhow, I was talking about current interconnection method, based on prefix, that none has regulated and nobody had tried (afaik) to make kind of agreements to use same prefix for same domain. The bad things is that the business cannot wait until ENUM is adopted in all countries, so you have to live without for a while and then will be pretty hard to teach your customers to adopt new contact numbers and so on.

Of course ENUM would be an ideal solution to this, let's see when it will be globally adopted.

Yeah, I have been swinging (not literally :-)) both ways on this, and enum if my preference, the short digits within networks are a stop gap, and will be dropped if enum gets moving, however for now I guess the 3/4 digit prefixes for each network are okay, having said that I cant see users really using it, in fact how many people here have interconnects, and actually have cross-network traffic (i.e calls/min) I know I have zero, and never had a request :-)

Please, forgive me if I'm making a dumb question, but for what I understood is that every client that has to dial to a number that is not configured at my SER routing Logics, i must be told what it is and the server in order to route the call at SER routing logics. I thought that every voip provider had a certain range ... like Global PSTN network around the world.
