We have spoken with many SMB owners at CIS and learned that many businesses think badly about call center solutions. Many believe that a call center must be large-scale and have many agents who can answer customer service calls. This is the old way of thinking. Many businesses should use call center solutions today, especially with the restrictions and lockdowns in Covid-19, and the rise of remote employees.
