Signed Call Traffic Gap Between Tier-1 and Smaller Carriers Undermining Robocall Mitigation Gains
Top US telecom providers¡¯ robocall mitigation efforts continue to yield positive signed call traffic results, as 85% of all traffic between these Tier-1 carriers was signed in 2025, and 93% of these were signed with the highest ¡°A-level¡± attestation.
However, °Õ±·³§¡¯ 2026 Robocall Investigation Report tells a different story for smaller carriers. Read the report to learn more about:
- The low levels of signed call traffic between smaller operators.
- Why slow progress in modernizing from legacy TDM to SIP networks creates vulnerabilities.
- How bad actors¡¯ tactics are making calls signed with ¡°A-level¡± attestation less easy to trust.
- The growth in multimodal and AI scam attacks.
