How do we talk about answering the phone? Well we don't say:
I'm sorry; I didn't get your phone.
No one wants you to get(take) his or her phone; get your own phone. (Ha ha.)
However, "get the phone" means "answer the phone (because it is ringing)."

Unlike in Japanese, in English, phone and phone call are two different things, conversation-wise, so--we say:

I'm sorry I missed your call.
