Connects is the opposite of Attempts. It's mentioned in our reports, being defined as "Calls more than 15 seconds in duration" but that's not the whole story.
As myphoner uses third party phones for dialing, we do not collect data about the actual calls. All we can measure is the time it takes from an agent view a lead, until they action it (choose an outcome for the call).
If it takes more than 15 seconds from the lead is first loaded, until a Call back action is performed, we assume that it was probably answered and a conversation took place. Therefore we say it is a connected call.
