Remind Me signals for missedcalls, voice mail or unread SMS. There is a possibility to choose Alert Tone and Volume for each of them. You can select the Profiles in which Remind Me will be active, so when you are having an important meeting it won’t be a problem. It doesn't sound an alarm during a phone call.
