ITU (International Telecommunication Union) created a country code +883 for the VoIP (Voice over Internet Protocol) in June 2008. When implemented, IP phones will be reachable from regular phones by dialing +833 prefix. IP phone users needs to get their iNum (International Numbers) to be reachable via +883. iNum is a country-less phone number so you can use it anywhere. As of it’s implementation with telcos, it remains to be seen. As of now, iNums are reachable only thru affiliate providers access numbers. Visit iNum for more details.
