Hi Richard and Alex, Thank you very much for the information. In our Kamailio configuration the rtpengine_manage() lines have "SDES-off", so presumably then we are using DTLS? Are either SDES or DTLS considered more secure or "better" in any way? On Wed, 10 Apr 2024 at 10:32, Richard Fuchs via

Hello, The encryption mechanism is called DTLS-SRTP, and you might think of it best as just TLS over UDP. The certificate is dynamically generated by RTPEngine. It is somewhat simpler than what you might think of as full-blown TLS. The APIs used for this are indeed OpenSSL. — Sent from

Hello, We're using kamailio, with rtpengine for RTP encryption/decryption. It works fine but I would like to understand the integration better. How does rtpengine get the TLS certificates, and what crypto library does it use (openssl?). Thank you in advance, -- David Cunningham, Voisonics

Hi All, I'm new to Kamailio but have been running dozens of Freepbx systems for the last 10 years. We are an Education Service District and service K-12 schools. Many of these we provide dial tone to, the rest we have connections to to provide for toll avoidance and backup outbound calling when

Hi community, I am preparing a setup of Kamailio with radius accounting on a docker-compose environment. When configuring the acc_radius module I had to navigate through some old doc by Daniel and inspecting the code itself. The thing is that it seems working, but not. And, yes, I already

Hello, I have remote users registering/ routing calls through my server. When calls do pass through the server, the server updates the from name, to uri and from uri via updating the pseudovariables $fn, $tu, and $fu respectively. While this is has been working, I do occasionally see calls
