The document outlines 7 signs that indicate an operation is a contact centre rather than a call centre. Contact centres provide omnichannel customer support through phones, email, social media, SMS, etc. whereas call centres only provide support by phone. Key differences include contact centres employing more skilled agents trained across channels, focusing on customer satisfaction through preferred channels, advanced agent training, integrated software tools, workforce management, customized agent desktops, and reporting/analytics. Ultimately, a contact centre provides omnichannel support while a call centre only uses phones.
