Clearly, these calls are unsolicited, so treating them as potential spam is wise. Callers using +15137663755 often show up repeatedly, making it easy to miss the real purpose behind the ring. A practical step is to let unknown numbers go to voicemail, then decide if a callback is needed. Register the number with the national Do Not Call list and consider enabling carrier‑provided block features. If the caller claims to be a telemarketer or a company, verify their identity before sharing any personal data. Staying cautious and using call‑filtering tools helps keep your line free from unwanted interruptions.
This number appears to be related to ADT or possibly a service like Pillar to Post.
This number has called me multiple times.
Telemarketer calling about extended car warranties. I told them no thanks, but they kept talking. Very pushy.
