When I saw this #, I let voice mail pick it up.. When replay voicemail, it had record something to the fact to "accept charges press 1". Sounds like someone made a call and wanted me to pay for it.
DO Not go to their website, (iwirelesshome.com). You will get malware/spyware and a rootkit installed on you PC just by checking the site. This phone - number/web site is a total scam. WHY CAN'T our lazy, good for nothing, local gov. do anything about this crap?
