I’ve been waiting for an auto-answer feature on iPhone for ages.
iOS 11 now includes that function. I’m off to upgrade!
Many iOS 11 features seem to be inspired by the jailbreak community. Among them, a brand new call audio routing option in accessibility settings that allows you to set your iPhone to automatically answer incoming calls on your behalf, should you wish so.
This optional feature supports regular calls via your carrier’s mobile network, as well as Wi-Fi calls, FaceTime audio and video calls and any VoIP calls originating from third-party apps that use Apple’s CallKit framework, such as WhatsApp, Skype, Viber and more.
To enable this feature, go to Settings ? General ? Accessibility ? Call Audio Routing.
There, you’ll see the call routing options which include settings like Bluetooth headsets, the iPhone speaker and more. These options are also available on prior iOS editions. But look at the bottom and you’ll see a brand new menu, labeled Auto-Answer Calls.

Tapping it takes you to a new screen where you can enable or disable the feature and set the duration of time your iPhone will wait when a call comes in before it’s auto-answered for you.
