Gathered

RJ has a conference call this morning. (RJ works from home most days.)

After logging on with the past code, he is informed on speakerphone by an automated system that the leader hasn't dialed in yet, and until then, "all participants will be placed on hold with music."

It made me laugh. As if without that statement someone might be unfamiliar with the concept.

What? What is this? Music?! I'm confused!!!
