Say what?

I'm now an administrator on a couple of applications within my work group. Today, I got an e-mail from a man who needed some help. His first name was Xiaolin. Now, I know that this is a Chinese first name, but I have no clue how to pronounce it. So I decided to call him and simply say 'This is Lime' and hope that he would say his name in response so I wouldn't have to butcher his name. The phone call went something like this.......

Me: Hello, this is Lime.

Xiaolin: Hi, this is Patrick. How are you?

Me: Good, thanks.

Yeah, so I'm guessing he's found a way around the whole name mispronounciation thing.
