Overhead paging (OHP) is
not working. (Continued)
The OHP may not be properly
installed.
 For OHP equipment connected to an FXS port, verify
WebUI configuration:
a. Connect a corded phone to the FXS port configured
for paging and verify that the phone rings when it is
paged.
b. If the phone does not ring, there is a problem with the
WebUI configuration or the installation at the ATA.
c. If the phone rings, the configuration allows
communication with the OHP. Verify your paging
equipment. Does it have power? Is it turned on?
 For OHP equipment connected to the AUX OUT port,
verify the correct cable connections. See “Connecting an
Overhead Paging System (OHP)” on page 55.
Refer to your paging equipment documentation if there are
still problems.
I cannot add a multi-zone
Paging Zone to other Paging
Zones.
Multi-zone paging does not
allow a combination of OHP
equipment and Desksets
within one Paging Zone.
 Page multi-zone OHP zones separately from extensions.
Unable to make phone calls
on the extension configured
for the FXS OHP jack.
System limitation.
 Once an FXS is configured for OHP, it cannot be used for
audio calls, nor will it receive voice calls.
