What you need to do is save this number to a new contact, and set that contact's ringtone to "no ring." Problem SOLVED. Works every time. Thank you 800notes.com. I never answer the phone if I don't recognize the number, and after a quick Google search and punching a few buttons on my cell phone, I will not lose any time to this solicitor again.
I get calls from them all the time. Like everybody is saying, it is Trulia trying to upsell. It's not evil, they have a good service for agents who might not be able to prospect very well. However, I get massive leads from my own "Homes for sale" site already ( www.virginiabeachresidence.com ) for way cheaper than a Trulia zip code thing. As a matter of fact, the training on how best to market my site was, collectively for the last year, cheaper than one month of a Trulia zip code. I compete with Trulia for keywords and win all the time. Good luck to you folks trying to sell Trulia, but there are more and more tech savvy Realtors out there every day that won't need you. As for the calls, I saved the number as "Spam" and made the ringer "No ring". Very easy.
