You just made my point I was trying to make..... many never heard of the other VRS's. lack of media, advertising, etc.In the last 5 years, I've only heard of PurpleVRS, Sorenson, and ZVRS. I'e never heard of the others... NEVER.
SprintVRS? I only remember SprintRelay (online relay service like IP-Relay).
The other vrs's were under the main ones you knew but FCC doesnt allow that anymore. There has been many many changes made that many dont know about.
