description: "Consumers rarely answer unknown numbers, causing legitimate business calls from pharmacies, banks, and delivery drivers to be ignored. Branded Calling addresses this by displaying a verified brand name, logo, and call reason on the recipient’s device to establish trust before the recipient decides to pick up. Twilio expanded Branded Calling to include AT&T (in pilot) alongside T-Mobile and Verizon, building on work since 2021 when they executed the first wireless call using Rich Call Data (RCD) over the PSTN authenticated with STIR/SHAKEN, and later documented the approach and brought the feature to general availability. Customer CareSignal, a healthcare engagement platform, saw a 21% increase in call answer rates. Twilio emphasizes that trust must extend beyond voice to channels like RCS, WhatsApp, Email, and Apple Messages for Business, so the same verified brand carries through every step."
