How to start BPO/CALL CENTER ?
I  want to open a call center. How to get started?  
 Starting a call center business can be an effective way to earn income while operating your own business. It is possible to run a call center from your home, but you can also rent an office space. Working from home can be a simpler way to manage a call center because it can be expanded into a full-staffed office later.

Overview  Call Center 
By definition, a call center is a centralized place where call   are answered.
However, call centers no longer handle solely          calls, nor do they need to be centralized. Sometimes the label of "contact          center" is          used to reflect that other forms of communication (such as email and          text chat) are also handled. Additionally, call centers can encompass          multiple locations, working together on one integrated system. In fact,          call center agents are even able to log in from their home and process          calls remotely.
Call centers can be "in-house" or          "outsourcing".  In-house call centers function as a part          of a business and provide service to that business.  An      outsourcing call center is a business that provides call          center services to other companies.

Another important distinction is that call centers can handle    inbound calls,       outbound calls, or    both.  Inbound call centers are reactive in nature and must          staff accordingly; they react to calls when they occur.  Outgoing          call centers, sometimes called telemarketing centers, are proactive in          nature, hiring and scheduling staff to make calls to specific          individuals at certain times.  Though seemingly similar in          nature, inbound and outbound centers have very distinct and dynamic          differences.        
Starting a call center is a complex, time-consuming, and expensive          task.  The steps to do so vary depending on rather you plan to be      an in-house or outsourcing call center.  Similarly, the equipment      that you need is different for an inbound center than it is for an      outbound center.
