Create an ad (advertising anything) on Vancouver CraigsList (http://vancouver.en.craigslist.ca/) and use their number and extensions in the ad. This should load their phone system for a while. Also probably good to use the 866 number (1-866-530-8472 ) in the ad as that will probably cost them money. I would suggest advertising something popular that will cause a lot of traffic.
The extensions for 360-892-6151 :
119 - Debbie Sandstrom
212 - Candy Snyder
211 - Tim Little
114 - John Kelly
120 - Nicole
I have receive a call from this number once a day around 3:30pm for the last nine months. I just ignore the number when I see it come across the caller ID. But I still have to go into my messaging system and delete the call which get tiring - and there is never a message left.
