Oddly, the silence after a call says more than any script. Repeated hang‑ups from +19542803087 are a classic sign of a nuisance telemarketing operation that uses automated dialing and drops the line when a live person answers. The best defense is to let the call go to voicemail, then add the number to your smartphone’s block list or use a third‑party call‑blocking app. Register the line with the national Do‑Not‑Call registry, and file a complaint with the FTC if the calls persist. Block the number, report the activity, and consider a call‑filtering service for added peace of mind.
