How to answer someone else's phone?

Question

I am in a Japanese office setup sitting next to my boss. He often gets phone calls but most of the time he is not in his seat. How do I answer his phone say that "This is Mr. XX's seat and this is YY (my name) talking and Mr.XX is not in his place" in Japanese?

Answer 1

I've found answering the phone at work follows a fairly fixed pattern.

I would answer the phone with something along the lines of:

株式会社ZのYYと申{もう}します。
This is company Z, MR Y speaking.

Then when they introduce themselves. You generally reply with :

お世話{せわ}になっております。

Then when they ask for your boss say something like:

申{もう}し訳{わけ}ないですがXXさんは席{せき}を外{はず}しておりますが...
I'm very sorry but he has left his seat...

At that point they will either ask when he will be back, or say they will call back later.

Answer 2

Two cases:

1. You answer saying "もしもし、JLU(の)クマーです", and the other person realises immediately you're not your boss

2. First, just say もしもし, let them introduce themselves, and then reply something like "あ、どうもありがとうございます。申し訳ないのですが、現在部長が席を外してますが…"
