Some users have recently noticed their calls to iPhone numbers are intercepted by an automated assistant (“IVR wall”), go straight to voicemail, or do not ring as normal. This is due to new call screening and blocking features introduced by Apple on iOS devices - https://support.apple.com/en-au/guide/iphone/iphe4b3f7823/ios.
What’s Happening When You Call an iPhone:
Call Screening: iPhone users can enable “Call Screening,” which means that when you call someone whose number does not recognise you, their iPhone may answer automatically. You may be prompted by the mobile system (using Siri) to state your name and reason for calling before the call is connected. If you do not respond, the call may not go through, or the recipient’s phone may not ring at all.
Silencing and Filtering: If your number is not saved to the recipient’s contacts, iOS settings may send your call directly to voicemail or flag it as spam. These settings are intended to combat unwanted calls and robocalls but may affect legitimate business or support calls.
Unknown and Spam Filtering: Calls identified as “unknown” or suspected spam by the phone or carrier may be filtered to an IVR, the recipient’s voicemail, or may even be blocked.
Impact on Outbound Callers:
If you hear an automated prompt (such as Siri asking for your name or purpose), this is Apple’s call screening system. Following the prompt increases the chance your call will ring through.
If your call goes straight to voicemail or is dropped, the recipient has likely enabled silencing, spam filtering, or do-not-disturb settings.
Calls from business numbers, call centers, or new numbers are often affected because they are not in the recipient’s contacts.
What You Can Do:
Be ready for a prompt: If you hear Siri or an automated system, speak your name and the reason for your call clearly.
Ask recipients to save your number: For recurring business or support calls, ask your customers to add your business number to their contacts.
Follow up via alternative channels: If important calls aren't going through, advise recipients to check their call settings or reach out via SMS/email.
Summary for Telco Customers:
Apple iPhones now use smart screening to block unwanted calls and robocalls. As a result, many legitimate outbound calls may encounter a screening prompt (IVR) or go directly to voicemail. Responding to the prompt and ensuring your number is recognised can help get your call through.
