I need to create a call centre that is going to be integrated in an website

The call centre has to be able to take the information from the front end of the website, to receive online call a to process all the massages coming from different media sources (Facebook, twitter, WhatsApp and others. We have to connect the call centre to an accounting program, so we will be able to mack invoices You have to integrate an system of online phone [login to view URL] or something similar An invoicing system [login to view URL] or something similar The call centre will have the main page where the call operators will identify the client his need and the operator will Macke the necessary correction. the phone nr or the email address in the system will become an id for the client (when the client is calling it will be identified by this system After the order is place is going to be sent to another person that is going to check the order and is going to place the order to our suppliers this person is going to validate the order and is going to decide the system that is going to deliver the order to the client ,also this person is going to mack the modification in the accounting system . We will need an window for him to wright the order for the driver (to go to pick up the goods and where to send it and the invoice ) the driver is going to receive the data as a list group by the name of the suppliers or the fast priority of the order Also we well have an window that is going to say the state of every order (if it was sent if is on the way the parcel nr if is sent with an different company [login to view URL] this is an example off call center
