Log in to your manager portal and go to “Campaign” – “View Campaigns” and choose the campaign you want to change the time. Please see below the section:

You have some options for setting time based on the time zone of your Dialer

So, if you choose time “default 9am to 5pm calling” it means that the

dialer will be able to call only within this time range. It will avoid calling your leads in their non-working hours
