Head of marketing department KingStyle
Simple navigation in the personal account, and we easily set up CRM integration in just a few clicks. Operators can make calls from anywhere in the country, without being tied to the office. To save operators' time on manual dialing, we installed an application that allows us to make calls with just a click.
