How to identify a callback server vs callback client (PPP)

Hi, can you help me to understand the following:

"Give the output:

myrouter#debug ppp negotiation

PPP protocol negotiation debugging is on

myrouter

%LINK-1-UPDOWN:Interface BRI0:0, changed state to up

BRI0:0 PPP: Treating connection as a callin

"

What is true ? (Select only one answer)

a)The local router is configured as a callback server

b) The remote route is configured as a callback client

In my view, based on the information extracted from the debugging output "Treating connection is a callin"

I understand that means that the remote router is configured

as a callback client. Answer b - OK.

However, doesn't that mean that the local router is configured

as a callback server ? If so, that would made answer a) correct as well. Confused.
