But now it is impossible to do it, because Accepted the law on the possibility of care to another operator while maintaining the number.

Please help come up with the most simple and fast algorithm for defining the number to the operator.

additionally notice that the option to call, then evaluate how much money went – it is not suitable, because The user of the number can change the operator quite often (on a historic scale).

found a solution. Keyword HLR.

HLR Lookup is something mean between WHOIS and Ping, but for phone numbers. There is (as it turned out) a variety of services that allow you to check the number. The only minus that they are all paid.

Here there is an API with examples
https://api.regius.name/ifaces/Phone-Number/#asterisk .
The base is updated often, but there are some restrictions in the free version.
It is convenient that MNC operator code shows, and the region code, and not just the name

Server gives an answer to JSON-format:
{“Phone”: “9123332211”, “Company”: “PJSC” Mobile TeleSystems “”, “Brand”: “MTS”, “MNC”: “01”, “Region”: “Kirov region”, “Kladr” : “43”, “Gibdd”: “43”, “UTC”: “+ 3”, “qty”: 48, “Limit”: 2000, “Answer”: “OK”}

and asterisk script (token you can not specify if it is not)

#! / usr / local / bin / python3
   Import Urllib.Request, JSON, SYS, PYMYSQL
   token = '98yysa8y8lnkn $ 27SDSKLDSK'
   With urllib.request.urlopen ("https://api.regius.name/iface/phone-number.php?phone=" + sys.argv [1] + "& amp; token =" + token) AS URL:
   Data = json.loads (URL.Read (). Decode ())
   IF Data ['Answer'] == 'OK':
     Print ('Exec Set Message = "Calling UTC' + Str (Data ['UTC']) + 'Region' + Str (Data ['kladr']) + '' + str (Data ['Region']) + ' '+ Str (Data [' Brand ']) +' "')
   ELSE:
     Print ('Exec Set Message =' + Data ['Answer'])
