It got through! The other two gathered around the Beard, looking excited. Although he was also excited, the Beard didn't his lose cool—after the call went through, he didn't immediately say anything. In general, when someone would take a call and didn't hear the other party say anything, they couldn't help but ask, "Wei? Who's there?"
That was just an inconspicuous little detail. The Beard well knew the importance of details. It was just such details that could allow him to take the initiative and to understand the other party more quickly. He could make a more appropriate response depending on the other party's reaction.
