Please allow us to change the repetition of notifications of unread messages. At times a person may not be able to check messages when one comes in, therefore we need a audible notification of an unread message. However at this time we can choose the number of reminders, but not how often. Every 2 minutes is extremely intrusive and annoying! To me as well as those around me. I need to get the reminders every 10, 20 or 30 minutes. Please add this option, for example 10 repetitions every 10 minutes.
