First step of a phone call

I asked colleagues through instant messaging on how to call into a Penang meeting from my hotel room in The States, here's a short part of the transcript.

"So, how do I call into a meeting in Penang from my hotel room huh? Please treat me as a noob and list step by step."

"First, you pick up the phone. Okay, I provided the first step liao, you all can continue."

"hahahaha!"
