When using the overhead paging system, you receive an error that says, "The paging system is not available."
Overhead paging systems
Verify if the customer's overhead paging unit uses FXO or FXS mode. This can be done by having the customer reach out to the overhead paging installer or by contacting the manufacturer to verify. Then set the proper configuration for the adapter.
Verify that there is no stuck call on the paging extension.
