Complaints about Phone Numbers714-559-####

Caller ID: SANTA ANA CA; which is the same city as our business, however every time I get a call from a number with this as the caller ID, all other time there was no one there when I answered or they would leave no message on our voicemail. This time, a man was there he asked if this was (our business name here) when I said yes, he asked said his name was Caleb White from some company name including the word "pipe" in it, he asked if he could speak to the person in charge of projects. I told him that he's busy and to leave a message. He asked if he could send an email introducing himself and to see if they were "a match" regarding some jobs coming. We do not or have ever used any service to help match us with jobs and I didn't want to give out any of our email addresses, so I asked him again to leave a message and his phone number. The number he gave me was different from what showed up on the CID (360) 573-6083 which may be a bogus number he just gave me because when I looked up the number it shows up in the White Pages website as belonging to a household with a completely different last name as his located in Vancover, Washington. Either way, I don't think he was truly calling from Santa Ana, or the (714) area code.
