U.S. carriers now require STIR/SHAKEN authentication for calls. Without proper digital signatures, your traffic risks being blocked, mislabeled as spam, or damaging your reputation.
Calls without valid tokens are often blocked before reaching recipients.
Spoofed or unauthenticated calls can erode customer trust.
Falling behind on STIR/SHAKEN compliance increases regulatory risk.
