Telemarketing is a method of direct marketing in which a salesperson solicits potential customers to buy goods, either over the unit or through a subsequent personally or Web conferencing appointment scheduled in the call. Telemarketing services require outbound calls created by BPO consultants to potential prospects to sell instant services maybe for any telecom provider, to retail households to market leisure holidays, to existing customers to market a new rate card for any mobile service provider in order to sell credit or debit cards and so on. These calls are created to generate interest in promoting and cross sell a great existing customer base in order to complete the income process online.
