Ticket bookings, hotlines or any kind of reservations are sometimes difficult to get through. Redialator, as auto redial app, greatly improves the chances of getting through by doing the all hard work for you.
You have unlimited redial attempts, you can turn speaker on and off and define number of seconds to countdown between calls.
IMPORTANT!!! Redialator uses native android phone app. In some cases native phone app won't automatically end call if it gets busy signal or somebody's voice mail etc. This means you would have to end call manually and Redialator will continue calling until it gets through.
