is displayed next to the Physical
Location Identifier (PLID) of the end point. You can clear the gateway trunks in the Gateway
Trunks form if the end points are unavailable or if you want to remove
a directory number (DN) that is configured for a specific device end point.
If a trunk end point is configured, but the hardware is not available
on the EX Controller (for example, if the hardware is removed), a warning
icon is displayed next to the Physical
Location Identifier (PLID) of the end point.
You can remove unavailable end points using the Clear operation.
To clear gateway trunks:
Go to the Gateway
Trunks form. 
From the list, select the end point with the warning icon next to its PLID.
Click Clear.
