What is call screening and how does it affect outbound calls?

Call screening refers to the process by which calls are evaluated or filtered before being answered, either by carriers, devices, or recipients. In outbound calling, this includes spam detection, call labeling, and consumer behaviors such as ignoring or blocking unknown numbers. Call screening directly impacts whether calls are answered, sent to voicemail, or flagged as spam. As a result, it plays a critical role in contact rates and overall campaign performance. Managing caller ID reputation, call patterns, and number strategy can help reduce negative screening outcomes.
