Pick how many people you call at once.

Same screen, same notes, same local numbers. The only thing that changes is how many calls are going at once.

Manual

one call

Paste a number and call. Who they are shows up beside the dial pad, so you never go in cold. Save the outcome and a follow-up before you move on.

For the one-off call

Power

one after another

Load a list and work it top to bottom. Finish a call, log the outcome, and the next person is already up. Callbacks that are due come first. With calling hours on, people outside their local hours are held back before you dial.

For working a list

Parallel

several at once

Put your headset on and Redialler calls several people from your list at the same time. The first one who answers is talking to you within the same second. The rest are dropped and saved as attempts. Only the real conversation gets recorded and noted.

Redialler pauses new calls on its own if too many answers go unconnected, so nobody answers to silence.
