Due to the unfortunate spam call era we live in, many calls from 1-800 numbers are never answered. This has presented a problem for our monitoring center to verify our customers false alarms, due to the fact the Monitoring Center calls you via 1-800-432-1429 or 1-800-633-4738. Please save both numbers in your mobile phone contacts to display as Alarm Monitoring. We also recommend including a subtitle under work or company to display Urgent Answer This Call. This info also needs to be passed on to your emergency list people.
