I am unable to access our paging system. I think it may be in a 'hung state'.

After the last person has completed their page, the paging system must hear 6 seconds of silence before it releases the line for another page to be placed. If the user did not correctly hang up then the paging system will revert to a maximum count of 35 seconds, at which time it then releases the line even if a page is still in process.
