June 2021 STIR/SHAKEN statistics
We examined SHAKEN call statistics from our ClearIP customers in June. They received signed calls from 131 originating providers in June, which gives us insight into trends in SHAKEN usage. We looked at similar statistics in March–April and again in May. Let’s have a look.
What proportion of terminated calls were signed? Of the signed calls, were there any verification errors?
|Certificate chain error||0.013079%||0.100030%||0.000103%||▼|
|Called number mismatch||0.001151%||0.064497%||0.393571%||▲|
|Calling number mismatch||0.003335%||0.012633%||0.075460%||▬|
|Invalid info parameter in Identity header||0.003049%||0.001455%||0.002544%||▬|
|Certificate repository error||0.000280%||0.000918%||0.001901%||▲|
|Invalid iat in PASSporT||0.000052%||0.000173%||0.003268%||▲|
|Invalid orig in PASSporT||0.000033%||0.000060%||0.000259%||▲|
|Malformed Identity header||0.000259%||▲|
|Invalid ppt in PASSporT||0.000259%||▲|
|Invalid dest in PASSporT||0.000259%||▲|
- The percentage of unsigned calls dropped about 3.3% per month.
- The percentage of signed calls increased about 3.1% per month.
- The percentage of signed calls with errors increased about 0.2% per month.
- The error rates are small, but increasing.
- There were three new errors types in June.
- Most of the PASSporTs with a verification status of Certificate chain error were signed with a self-signed certificate. This error has been trending down, and dropped significantly in June.
- Most of the PASSporTs with a verification status of Called number mismatch had an invalid number in the dest claim of the PASSporT. This error has been trending up, and increased significantly in June.
- 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. This error increased sharply from April to May, but has decreased in June.
What attestation levels are originating service providers using?
|A — full||98.919207%||98.656891%||89.242506%||▼|
|B — partial||0.731490%||0.982837%||3.540120%||▲|
|C — gateway||0.349303%||0.360271%||7.217374%||▲|
This is an interesting trend. Full attestations started very high in April, dropped slightly in May, then dropped significantly in June. Gateway attestations picked up most of the difference, and partial attestations are emerging.
Originating service providers signing calls
There were many more Originating Service Providers (OSPs) signing calls in June than in previous months.
The number of OSPs doubled in May, and more than doubled again in June. Impressive growth, and more to come:
- There are 295 authorized service providers listed on the Policy Administrator website as of this publication date.
- As of July 1, 2021, 1,025 U.S. service providers had certified that they have either a partial or complete implementation of SHAKEN.

Because access to numbers is no longer a requirement to receive and Service Provider Code token, some Service Provider Codes are not in the LERG. We left the LERG company name blank for those providers in this table.
Note that the above data reflects both call volume and SHAKEN activity. The data shows 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 includes only originating service providers that had at least one successfuly verified call received by a ClearIP customer.
Certificate repositories caching and latency
What are typical certificate latencies, i.e., time-to-fetch, and why? This was one of the most surprising results in both the March/April and May statistics. Several Certificate Repositories were adding significant latency and post dial delay to calls because they were not set up to use cache control.
Latency has generally improved for certificate repositories that have been up and running for a while. It seems they have tuned their cache control. Some of the newer certificate repositories have less caching and higher average latency.
|Certificate repository||% of all verified calls||Cache hit %||↑ Avg latency (milliseconds)||Avg latency excluding cache hits (milliseconds)|
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.
- The proportion of signed calls has increased about 3% per month.
- SHAKEN verification errors have increased about 0.2% per month.
- Full attestations are down but still dominate. Gateway and partial attestations have increased.
- There are more OSPs signing calls (131). Still a long way to go to match the number of authorized service providers (295) and the number of U.S. providers that certified they’ve implemented SHAKEN (1,025).
- Several certificate repositories have improved caching and decreased latency. Some of the newer certificate repositories have not yet done this.
In addition, we help service providers with all aspects of STIR/SHAKEN deployment, including registering with the Policy Administrator and filing their certification with the FCC.
