To start a 10 seat call center for a predictive dialer you would need different services like phone, The host server computer to load your dialer software licenses onto, telephone board, network switch, USB headsets, and cables. and other expenses like Installation and training charges.So for a 5-50 seat call center I will suggest you do go for that much investment, Recently a new mobile Dialer introduced. known as “My Sales Dialer”. This is an android based app available for only $9.99 one time fee. Once you install it into your android phone, it turns your phone into powerful dialer. after that you only need to pay operator charges, nothing extra. I found it very user friendly and there is no need of training to use the app.
