I do not know why but redial applications are rare. I do not like any of them so I wrote one myself.

Usage

Simple Redial calls the most recent number in the dial history. No history, no call. Tap and hold the most recent number label at the top of the screen to select dial history filter (All,Missed,Incoming,Outgoing).

Call attempt number and time between call attempts can be selected by tapping and holding the labels.

On tapping Redial the program starts the call attempts and goes on until one of these happens.

The 'not connected' notification is played when the phone call is not active and is so a 'normal' notification. Therefore, you can control it with volume and vibrate/silent settings.

The 'connected' notification is played when the phone call is active and this is somewhat tricky. You can not control it with volume and vibrate/silent settings but you can select whether it is played on speakerphone (check Sound on Speakerphone) or on the phone speaker (uncheck Sound on Speakerphone).

Tweaking

The sounds used by the program are Connected.wma and NotConnected.wma in the installation directory. You can change them if you like by replacing these files. If your Connected.wma is longer and gets truncated you should change the registry HKCU\Software\SimpleRedial\ConnectedSoundSecs. This is the time in seconds the program allows for Connected.wma playing before exiting.
