Taking calls while playing music on your thumping Bluetooth speaker can be annoying, especially when the iPhone is kept away. In this case, it’s great to redirect calls to the speaker and answer directly if it has a built-in mic. Depending on the mic’s quality, taking calls may not be as good as on the iPhone, but it can get the job done to address quick communication. If you want to give a try, let us walk you through how to route iPhone calls to a speaker or Bluetooth headset.

How to Set a Bluetooth Headset or Speaker as the Default Audio on iPhone
Your iPhone has a built-in option of Call Audio Routing that lets you use your headset or Bluetooth speaker to receive and answer calls. Before you turn it on, make sure your speaker and iPhone are connected with each other via Bluetooth.
- Open the Settings app on your iPhone.
- Go to Accessibility settings.
- Tap on Touch.
- Next up, Select Call Audio Routing.
- Now, choose Bluetooth Headset or Speaker as per your choice.
Now when you receive a call on your iPhone, you can answer and talk through your speaker.
Auto-answer Calls is another most useful feature in accessibility settings. If you often get caught up in a situation when you can’t manually accept calls (whether your hands dirty or iPhone Screen is broken), you can enable it and let iPhone automatically accept the call. To do so, go to Accessibility → Touch.

Call Audio Routing → Auto-answer Calls → Enable the toggle.

At last, don’t forget to set the wait-time before your iPhone auto-answer the call.

Switch Between iPhone and Bluetooth Speaker During Calls
If you’re using it in a noisy place, it is possible the person on the other end may have a problem hearing you due to average mic quality. In that case, if you want to switch from Bluetooth speaker to iPhone, you can do it directly from the dialer screen.
While on call, tap the audio button → select iPhone from the options.

I am an aspiring tech blogger who is always in love with new generation iPhones and iPads. At iGeeksBlog, I am dedicated to rendering the How-To's, Troubleshooting bugs, and reviewing apps that are a great deal of help. When I am not writing, I am daydreaming about the future of all things Apple and watching videos of smartphone battles on YouTube.
Thank you!! Apple blogs were not helpful for this issue. These instructions were applicable to current versions of iPhone and solved my problem quickly.
Tried this in a store with my iphone 7 to a panasonic 209 sound bar and it would not work
I am sorry to hear that as this trick normally works like a charm. And there can be two key problems here, Bluetooth connection between the speaker and iPhone could be weak or some issue with the speaker, try again with some other model.
You should publish many more works like this… Thank you, Regards
Most helpful notes on call routing. I would really appreciate it. Thank you
