iPhone: is it possible to route calls to speaker only if answering via smartwatch?

Question

Usually I answer calls with the standard iPhone receiver. Sometimes, while the phone is charging and I'm in the other room, I have to answer the call with a bluetooth-connected smartwatch (otherwise I wouldn't make it in time,) then I have to run to the other room and press the speaker button to start the conversation.

Note: on the smartwatch I just press "answer call" but it has no speaker, so the call is completely handled by the phone itself.

I know it is possible to route audio to the speaker by default, but is there a way to do that only if I'm triggering the "answer call" from the smartwatch?

Answer 1

No, that's unfortunately not currently possible.

As you indicate, you can use the Call Audio Routing functionality in Accessibility to always route any call to speaker. However, you cannot do that just for calls answered through a Bluetooth-enabled smart watch.
