help with comprehension of conversation

[letslearn]

Hi guys,
I was wondering what the last line means of this conversation. It is from a textbook.
受付 reception desk, information desk etc.
呼び出す can be to call to summon etc.
てもらう to do for someone or receive a service....?
The conversation is as follows:
<デパートで>
のり子さん：カルロスさんはどこ？
ノｰｲさん：さっきからいないけど。。。。
のり子さん：受付で呼び出してもらいましょう。
Is it like this.
Where is Carlos?
He hasn't been here for quite a while.
He has be called to the information desk.

How does the てもらいましょう work here?

よろしくお願いします

Thanks toritoribesan.
Yes its the volition which means let's.
So it is more like
Lets have the reception desk call him out.

I had this tunnel vision of Carlos being already called to the desk. I think I mixed ましょう with でしょう.
Like she was saying I wonder if he has been called.
