Recent STIR/SHAKEN statistics
We’ve looked at call statistics from our ClearIP customers for the last 45 days to see whether they’re getting many calls that were signed using STIR/SHAKEN. Here’s what we found.

Most of the PASSporTs with a verification status of Certificate chain error were signed with a self-signed certificate.
Most of the PASSporTs with a verification status of Calling number mismatch had a valid number in the orig claim of the PASSporT but had anonymous in the From and/or P-Asserted-Identity header.
Most of the PASSporTs with a verification status of Invalid info parameter in Identity header had an info paramater that contained an HTTP URL instead of an HTTPS URL.

Note that the above data reflect both call volume and SHAKEN activity. The data show the proportion of successfully verified calls received by ClearIP customers for each originating service provider as a percentage of all successfully verified calls. If a small number of calls were received from an originating service provider, then percentage of successfully verified calls received by ClearIP customers would be low, even if the originating service provider signed a high percentage of their outbound calls.
The above data include only originating service providers that had at least one successfuly verified call received by a ClearIP customer.
What are typical certificate latencies, i.e., time-to-fetch, and why?
|Certificate repository domain||Cache hit percentage||Average latency including cache hits (milliseconds)||Average latency excluding cache hits (milliseconds)||Cache-Control header time (seconds)|
Retrieving a certificate from a certificate repository takes time, or latency, which increases Post-Dial Delay (PDD). If a certificate is cached by the STI-VS, then it does not need to be retrieved.
A certificate repository can be configured to provide a Cache-Control HTTP header, which tells the STI-VS how long to cache the certificate after retrieving it. If a certificate repository does not provide the Cache-Control header, the STI-VS does not cache the certificate or caches the certificate for only a short time.
Note that the ClearIP STI-VS caches certificates for 60 minutes if the Cache-Control header is not set by the certificate repository or if the Cache-Control header contains a value of less than 60 minutes.
