Integrated Solutions · Voice Verification (OTP)
Let the phone read the code, not SMS.
Your software provides the number via API; the PBX calls and reads the verification code digit by digit (1 = repeat), then hangs up. It bypasses SMS sender ID, İYS and delivery problems; the code is stored hashed and verification is done via the API.
