NETWORK OPERATORS’ A2P REVENUE

IN DANGER

Integral to authentication, flash calls deliver one-time passwords (OTP) within 
number digits as zero-duration calls. Since these calls are not answered, they don’t 
generate any revenue, leading to detrimental A2P SMS revenue losses.

  • How the Situation

    Looks Today:

    • A2P voice authentication is becoming a cost-efficient alternative 
to SMS OTPs for 2FA.
    • Major players use flash calls for secure user authentication during
logins or sensitive transactions.

  • Challenges

    and Consequences:

    • AI Shield detected 14-25% of operators’ international voice traffic as flash calls, which causes major A2P SMS revenue losses.
    • There’s no industry consensus on how to treat flash calls – meanwhile, they disrupt relations with interconnect partners.
