I have a sx-200 icp in a hotel. there is a superset 4025 in the laundry that continues to receive reminder calls. with a softkey of 'confirm' something to that effect. the phoen will ring all day long. if you hit confirm it will stop for a little while. I found the phone was in the same cos as the guest room and i changed that but it made no difference. is this a voicemail reminder? Should we simply dial into the mailbox and delete messages? it drives the staff nuts
