Robokiller uses Conditional Call Forwarding (CCF) to screen calls when your line is busy, unreachable, or unanswered. This is what allows voicemail and other features to work properly.

👉 Carrier’s voicemail

Carriers like AT&T and T-Mobile support CCF smoothly.

• In this case, your voicemails go to your carrier’s inbox

• You won’t see or listen to these voicemails inside the Robokiller app

👉 Robokiller voicemail

If your carrier doesn’t support CCF, no problem—Robokiller offers Hosted Voicemail.

• Your voicemails will appear in the Voicemail tab inside the app

• This tab only shows up after you receive your first Robokiller voicemail

👉 How to switch back to your carrier’s voicemail

1. Tap the Settings tab in the Robokiller app

2. Under Voicemail Settings, tap Voicemail handler

3. Select Phone to use your carrier’s voicemail
