You can make phone calls automatically using an auto dialler app. Most contact centre software solutions and business phone systems offer it as a built-in feature. Once you activate the feature and configure it as per your needs, it starts dialling numbers from a pre-set list of contacts.You can use an auto dialler app in different modes. For instance, the power mode dials a new number after the agent has completed the previous call. Predictive dialling dials many numbers simultaneously and connects live calls to available agents. You can choose the preview dialling mode to check customer information before dialling.Further, you can decide what to do once the call connects. You can direct the call to a live agent or play pre-recorded scripts to make a sales pitch. You can also drop a voicemail message if the called party does not answer.
