You are able to add another phone number to an active call by using the “Conference Call” feature on the dialer. Once the other party you conferenced in is connected, you will be able to hang up while allowing the current call to stay active with the other 2 participants. You can also see the active participants, as well as mute them or drop them from the call.
Pricing for conference calls:
Your Ringy account will be billed for the duration of each outbound call leg. That means each time you add another party to this call, you will be charged the standard pricing per minute for that call leg for as long as the other party is on that call. For example, if you add another party to this call and then hang up, the other parties may continue the call and you will be billed for the duration of their call when the call is finished.
