Whether you are in IT industry or any other industry, if you are willing to establish a call centre in India you need to take approval for it from Department of Telecommunication (DOT).
To start a new mobile service in India, every foreign enterprise needs to take approval from Dot, only then they can provide these services in the country. Once the company completes all the formalities, DOT provides them the license to deliver their services in the area assigned to them. However, whenever DOT wants it can cancel your license. There could be any reason for the cancellation of your license, such as incomplete documentation or may be the security concern.
Thus, if you are too willing to start a call centre or you too want to establish your mobile phone service in India you need to register yourself under the DOT. However, it is a simple process but still if you are doubtful and you want to seek some help then there are several consultancy firms running in India that provides DOT licensing consultancy service on a reasonable price.
