This book starts with information on Hosted Telecom/Call Center Services, because this is a relatively unknown discipline, which may provide time and money saving options in a call center environment. Supervisors and managers may address more urgent matters, matters which should be their core business: customer friendliness, optimizing agents' skills. The book further deals with communicative AND commercial skills, telesales, the sales process, call center operations, mystery calls, and enhancement of the self-image which makes for better performances.
