How Do We Stop Repeated False 911 Calls Linked To Our Address?

Over the past three weeks, local police have come to our home six times in response to repeated 911 calls that appear to originate from our address. The officers have said the calls are coming from what they referred to as an “Obama phone” (an emergency phone) with no area code. We’ve checked all the devices in our house (phones, tablets, watches, laptops and we have no landline), and none are making these calls or match the number they’ve identified.

This is becoming a major issue. The police are being called out late at night or in the early morning hours, wasting time and resources. We’re also worried that if we ever need to make a legitimate 911 call, there might be hesitation or delays in response.

How can we address this? Is there a legal process to help locate the source of the calls or stop this from happening? Should we escalate this beyond the local police? Any guidance would be appreciated.
