So here is what I can tell you..... after doing about an hours worth of research.... all of these phone#'s are owned by the following Company(s).
TM Caller ID - you can reach them at the following 1-866-225-1956 or 503-226-4444 have fun they answer; talk to David he is not much help :)
or call them at
Wildgate - 310-861-6100
last but not least is
Digitcom Services, Inc. 866-225-1956 doesn't that number look the same as the one above? So if you want to do something....
Register your phone# on the do not list WWW.DONOTCALL.GOV or call toll-free, 1-888-382-1222.
then make sure you report the number that called you and then reference all 3 of the above companies with the Federal Trade Commission
there phone # is 1-877-382-4357. Oh yeah don't forget to call your attorney generals phone and report it there also. I figure someone has to listen if everybody complains.
