It's a lie. When the announcement came out I checked with the big players in the online meeting space and every one of them (except one, IIRC) said they've had that feature well before ZRFY added it to Zerify Meet.
BTW, the reseller touted in that announcement, 323Link has Zerify listed on their web site, but they only mention the crappy Zerify security products. For video meetings they list Jitsi, Highfice, GotoMeeting and WebEx. Why would a company like 323Link risk its reputation selling an known product like Zerify Meet? My money says the product was never installed in the Tennessee Courts.
