Why do you need to talk to them on the phone? Most girls wouldn't want to sit there chatting to a guy they barely know on the phone anyway (at least I wouldn't) Just keep it short and simple. Ring her up, say Hi it's Joe Blow from the club! Do you wanna meet for drinks on Thursday night? About 8? Cool I'll see you there!". If the phone really scares you that much... just send a text message! My current boyfriend sent me a text message the first few times, and I didn't mind! It made me more comfortable too... coz I had time to think of what to say.
