This is a project where we get the CDR from Telecom operators and we have to re bill them to our cleints for each call record.
We have to read/upload CSV files and then put them into a database and then bill them to various clients with putting our own charge on it. the billing is to be done country wise and there are total of 20 countries. We should be able to have as many clients in each country and the charge for each client will be different. once we charge the cleint we have create a CSV file of his calls cdr and the total in the end in the cdr. then we have to generate the bill.
I have attached the code along with this so that you can understand the concept, this is a part code for a few countries and others have to be done in a similar way, I would be willing to discuss more in detail once you are interested.
