Add Built-In Phone System

Our team exports a lot of data from God Mode to our power dialer to rapidly call and vet new buyers. The problem we run into is toggling back and forth between our external dialer and Investorlift. If Investorlift added a built-in dialer, it would make this workflow 100X easier for our Dispo Team! In addition, if we could track in-bound calls about properties, it would help our management team stay on top of our Dispo Managers, ensuring that each in-bound call about a property is answered with a quick response time.
