this number appears that it is an outgoing call from my home, this is not possible since i was alone at the time of all the calls??

Do you have Teleblend / SunRocket?  It is the number dialed for voice mail when you check your messages by dialing "00" from your phone.

Ha Ha!
Thanks jgw for the info. I was also initially surprised that someone was able to hack our phone line too.....:-)

So glad I checked this out!  I was a bit alarmed also when I discovered the same thing as "mims".  Thanks for the info, "jgw"!

This code is not listed for the USA or Internationally. However, the Afghan CAA (Civil Aviation Authority) has fax numbers that begin with 873; even though their national calling code is 93. So I don't know what to say, except that the scammers know how to send a fake phone number to the receiving phone.
