How do you handle fake numbers and spoofing?

Spoofing — a call displaying a fake number — is detected by cross-referencing: signaling inconsistencies, impossible call patterns, numbers reported in bulk too recently. Those calls are filtered without a text, like classic spam, and appear in the filtered-call history with their reason. The honest limit: no filter in the world blocks 100% of spoofing, especially fresh campaigns whose numbers aren't reported yet. The consequence for you stays small: a text sent to a fake number vanishes into the void at nearly no cost, and the fake lead doesn't pollute your statistics once tagged.
