We have purchased a chat
How it works: there are our operators who are logged in to receive a customer's call, and talk to customer.
There are also the customers themselves who log in to talk to our operators for our services.
When a customer logs in the chat, customer's signal is visible to one operator at a time. If the operator does not accept the customer in a set time, the systems switches the customer's signal to next operator , however always to one operator at a time.
We need the source code of the product so amended, so that the system sends the visitor's signal to all operators at once, without affecting current functionalities of the programme.
