Before calling, think about some topics that you know interest him. Discussing a movie he likes, a sport he plays, or a video game you now he plays are good ways to get him talking and to learn more about him.

How have you been?". People generally sound different on the phone than they do in real life.  If someone other than the guy answers the phone, don't be nervous to ask for him. Just be polite and ask if he is available. If you get his voicemail, stay calm. Leave a message, letting him know who you are, your number, and...
