Frequent daily calls that abruptly hang up upon answering point to persistent unwanted contact. This pattern often signals harassment calls, where the caller may be testing active numbers or engaging in nuisance behavior without a clear purpose. Telecom patterns show such tactics evade tracing, frustrating recipients. To counter this, enable call blocking on your device immediately, register with national do-not-call lists like New Zealand's, and report to authorities if it escalates. Avoid answering unknown numbers; let them go to voicemail to gather more intel. If needed, contact your carrier for advanced filtering options to reduce the annoyance.
Frequent calls occur nearly daily; when I pick up, the line disconnects immediately.
