TransNexus comments on FCC robocall blocking notice
The FCC issued a call for comments on proposed rulemaking for robocall blocking. TransNexus responded to share our experience in deploying STIR/SHAKEN and robocall prevention solutions in telecom service provider networks. Here are highlights.
- In working with service providers, we’ve found that many would rather give each customer choices on how or whether to block robocalls. One size doesn’t fit all.
- We do not think that safe harbor should depend upon the degree of attestation.
- We agree that safe harbor should cover blocking unsigned calls from providers who are participating in STIR/SHAKEN.
- Safe harbor should not be limited to blocking calls originated by providers who neither sign calls appropriately nor participate in the traceback group.
- Smaller, rural service providers cannot participate in STIR/SHAKEN as easily as larger carriers. Their calls transit several interexchange carriers—if any segment doesn’t support SIP over TCP/IP, then the Identity token will be lost. This is completely outside of the control of the smaller rural service providers.
- Out-of-Band SHAKEN call authentication is a technical solution to this problem. It enables any service provider to participate fully in STIR/SHAKEN regardless of the network readiness of transit carriers who route their calls.
- Many providers with legacy networks could participate fully in STIR/SHAKEN today by using a TDM-to-SIP gateway and a STIR/SHAKEN software solution that supports Out-of-Band STIR/SHAKEN call authentication.
