When he called the first, he got the guy's wife; she gave him a work number for her husband.

I left a return message at his work number: all quiet on the western front.

I risked a call there to get your work number.

Ten minutes later he calls me on my work number.

Standing just outside Rachel's room, he called the work number on his cell phone.

"Do you happen to have a work number for him?"

It was about seven her time, so I called her work number first.

I think that's fine if you give them your work number.

He would have tried her work number, but she'd never gotten around to giving it to him.

I left a message for a callback and tried her work number.
