http://ttcpa.oklahoma-isp.net/telemarketers.html  See this website, that lists TX telemarketers,for further info.  This number appears to be the fax number for a telemarketing enterprise listed as Life Corp., Voice Ventures Inc., Fidelity Checks Inc., and Relationship Foundation, all based in Arlington, TX.  According to the website, these entities have already been cited by the FCC and at some point, the Atty Gen of TX filed suit against them.  These entities may or may not still be in operation.  Voice Broadcasting Corp is/was listed at the same address but registered in South Dakota.
