Our phones are capable of using the default system ringtone and 3 additional ringtones that can be customized by the administrator (IT Services). We are currently experimenting with ringtones, trying to find professional sounding ringtones. Each of you may select any one of the four available ringtones. The video below walks you through the process.

Note: You may need to set these each day until I figure out how to keep it from resetting each day.
