It's like dry-humping but involving a phone. It's basically a dry run on a phone call. You're not doing it for real. It's when you want to call someone but chicken out and only dial the number but never press Send or never quite finish dialing (if on a non-mobile phone).
A: "did you call him yet?" B: "I'll call him tomorrow. So far I've only been dry calling."
