I'm curious why companies like T-Mobile and Inteliquent/Onvoy/Voyant continue to retain company names and corporate entities long after their brands have been retired, acquired, and generally shell entities holding phone numbers. Some examples: T-Mobile -> Omnipoint, Aerial Communications, Suncom, Powertel, Sprint, Eliska Wireless Ventures Subsidiary I Sprint -> O1 Communications, US Telepacific AT&T -> New Cingular Wireless, Southwestern Bell, Pacific Bell, Bell South, Southern Bell, Ameritech Verizon -> Cellco Partnership, Bell Atlantic Nynex Mobile Inteliquent -> Radiant IQ, Onvoy, Voyant, Broadvox, Layered, Neutral Tandem CenturyLink -> United Telephone, Qwest Spectrum -> Charter Fiberlink So many of these brands are dead and acquired, yet these companies live on and own phone numbers. Cingular died in 2006. Radiant IQ acquired in 2015. Bell Atlantic went away in 2000 with Verizon acquiring Bell Atlantic and GTE. Why? What benefit does this provide the owning/operating companies? Legal insulation? Beckman PS -- This all started when I saw Inteliquent request VoIP Numbering for Radiant IQ in June 2020, a company they acquired in 2015, and generally does not exist in any meaningful way to customers or consumers, residential or business. This industry in the US is weird. --------------------------------------------------------------------------- Peter Beckman Internet Guy beckman at angryox.com https://www.angryox.com/ ---------------------------------------------------------------------------
