How to send spam calls directly to voicemail
iPhone
If you want to send scammers directly to voicemail on your iPhone, you must have iOS 13 or later installed. Some phone carriers let you detect Junk callers and silence them, while some carriers only let you display the caller’s business ID information when calling.
You can also silence unknown callers which is a great option to send any call from someone you don’t know directly to voicemail.
Call Blocking & Identification
- Open your iPhone Settings > Apps
- Scroll down and tap Phone
- Tap Call Blocking & Identification
If your phone carrier offers it, you can toggle on:
- Silence Junk Callers – this option will automatically silence calls your phone carrier thinks is spam or junk
- Business ID – this option will display the caller’s verified business ID so you have a better idea if it’s a junk caller or someone you may know
Silence Unknown Callers

- Open your iPhone Settings
- Scroll down and tap Phone
- Tap Silence Unknown Callers
When this is toggled on, any call from someone who isn’t in your contacts, recent calls, Siri Suggestions, or texts will get sent straight to Voicemail.
Android
This was tested on a Samsung Galaxy. Settings may work on other Android devices although it may vary depending on your Android phone’s manufacturer
If you have a Google device like a Pixel that is updated or is from 2018 or later, your phone has a feature to filter out spam calls automatically. You can block (and sometimes report spam) calls in your phone’s settings.
- Open the Phone app on your Android
- Tap the three dots for more menu options on the top right
- Tap Settings
- Tap Caller ID & Spam (this may be listed as Caller ID and Spam Protector or not listed at all, depending on the carrier settings)
- Toggle on “Turn Caller ID & Spam”
- Turn on “Filter spam calls” or “Block spam and scam calls” which will send them straight to voicemail
