I have not checked these since I went to Window Mobile 6.1, but here is what I have in my notes for 6.0. I also seem to remember that this may cause them to keep repeating forever.

Enabling Repeating Alarms
===================

1. This will enable the "Repeat" option within Sounds and Notifications for Phone: Missed Call.

Changing this registry setting enables the Repeat option as well as "Flash Light for 15 minutes". You can make changes to any of the options, as needed and the Repeat should stay enabled.
