In a mobile telephone network you can register non-greographic numbers, these are usually used for companies, for example 0800, 0500, etc. These numbers are registered in a routing table, which allows you to dial the route to the nearest office of the company you are calling. My question is how to list non-geographic numbers and know which company they belong to? |
