If the notification device is a home phone or another phone away
from the office, ask the user to have someone available to answer the phone
during the test.
Confirm that the notification device is on.
Set up a test phone (Phone 1) for single-line testing. Use a
line connected to a port that is set to dial out for message notification.
On Phone 1, dial the notification number set in Unity Connection
for the device.
If the pager is activated or the phone rings, you have confirmed
that Unity Connection can call the device.
If the pager is not activated or the phone does not ring, there
may be a problem with the device. Consult the documentation from the device
manufacturer, or ask the user to obtain a different notification device and
repeat the test.
