Number-level features are evaluated on every inbound call before routing occurs.
-
features.stop_call - Prevents the call from completing. Use this for credit control or to temporarily suspend call routing for a number.
-
features.call_verify - Requires the caller to press a key before the call connects. Use this to reduce spam and robocalls.
-
features.scheduled_call_verify - Same as call_verify, but only active during configured time ranges. Use this to apply the key-press challenge after hours without disrupting the experience for legitimate callers during business hours.
-
features.call_tag_rules - Applies call tagging rules to every inbound call on this number.
For call_record and whisper, where you configure them depends on the route type:
-
Basic - Configure at call_routes.route.features.call_record and call_routes.route.features.whisper.
-
Geo, ZipCode - Configure per route at call_routes.routes[].features.call_record and call_routes.routes[].features.whisper. This allows different recording or whisper behavior on each route.
-
FollowMe, TimeOfDay - Configure at features.call_record and features.whisper. These route types do not support per-route feature configuration.
