Sending your calls to an automatic answering service is no way to build a relationship.
That's why we made sure that all of the calls that goes to your Respond Flow number will reach you.
The calls will be forwarded to the number associated of the original account creator of your Respond Flow account.
To change it, go to your account settings and update the number listed under your "User Details" and click "Save". Future calls will go to the new number.
