Kamailio 6.1 Released

Kamailio 6.1.0 arrives with four new modules and a wide range of improvements that continue to consolidate the multi-threaded architecture introduced in 6.0. It also incorporates the improvements from the 6.0.x branch (6.0.1 through 6.0.6): extensive enhancements to the CMake build system, export of functions to calculate HA1 and authentication response to KEMI, parsing of the From header in the initial header phase, improvements in xhttp_prom for exported metrics, and fixes in dispatcher, rtpengine, IMS, topos and tls.

New modules

auth_arnacon – cryptographic authentication based on ENS (Ethereum Name Service)
auth_web3 – blockchain authentication with integrated ENS support
peerstate – management of peer registration and call states
ptimer – execution of routing blocks based on precision timers
