Telo’s nuisance call detection utilizes a diverse set of signals derived from a comprehensive group of high-quality data sources in order to identify unwanted calls without flagging legitimate calls incorrectly.
SHAKEN-enabled phone calls include an access token in the call header. OpenCNAM’s SHAKEN Verification service can easily verify the access token and at the same time perform the CNAM query and nuisance detection. So, in one query, OpenCNAM can return any attestation in addition to identifying the caller.
Telo has partnered with Somos to provide a solution to a problem that no existing solution has been able to adequately solve -- launching the first ever authoritative database of Toll-Free CNAM records.
