Learn how to block VoIP and internet calls on your Android device with these easy steps. Prevent unwanted calls and spam.
What are VoIP Calls?
VoIP (Voice over Internet Protocol) calls are phone calls that are made over the internet, rather than traditional phone lines. Examples of VoIP services include Skype, WhatsApp calls, Facebook Messenger calls, Google Duo, etc.
While VoIP services provide a convenient way to make inexpensive calls, they can also be used for unwanted spam calls and robocalls. Blocking VoIP calls on your Android phone can help reduce these nuisance calls.
How to Block VoIP Calls on Android
Here are a few simple methods to block VoIP calls on your Android device:
Use a Call Blocking App
Install a call blocking app like Truecaller or Hiya to automatically detect and block spam calls. These apps maintain a database of known spammers and robocallers to prevent their calls from reaching you.
Block Calls from Specific Apps
Go to Settings > Apps & notifications > Advanced > App permissions > Phone > Blocked numbers. Here you can select apps like WhatsApp, Skype, etc. and block all calls from them.
Enable Do Not Disturb Mode
Activate Do Not Disturb mode on Android to mute all calls, except those from contacts you select. This prevents unwanted VoIP calls from disturbing you.
Block Calls from Unknown Numbers
Go to Settings > Blocked numbers > Block unknown callers to automatically block all calls from numbers not in your contacts.
