Recently a new module has been imported in Kamailio git master branch – secsipid:

It implements the IETF extensions for Secure Telephone Identity (RFC8224, RFC 8588), known as STIR and SHAKEN. Their scope is to detect and prevent SPIT (SIP/Telephony spam calls) and robo-calling, allowing the SIP/VoIP providers and carriers to assert and validate the identity of callers. Currently the authorities in USA are pushing for implementation of those extensions, in the first phase by the major telecom companies.

The module relies on a library made available by Asipto at:

The secsipidx project offers also a CLI tool and an HTTP API server for checking or building SIP identity.

You can learn more about this module, or STIR and SHAKEN in general, at SimCon3  (March 5-6, 2020, in Bristol, UK) and the next Kamailio World Conference (April 27-29, 2020, in Berlin, Germany) where Daniel, the author of the module, will participate.

Thanks for flying Kamailio!
