[Kamailio-Users] Phones that support TLS with certificate

Hello, I am trying to find the phones that can use tls with certificate, I mean that the phone doesn't accept incoming calls unless the server certificate is signed by a public authority or manually added to a list. For now my conclusions are: -Snom 360 - works with TLS. But although snom wiki states that a certificate is needed, incoming calls are accepted even if the certificate is not uploaded. -SJPhone - same as snom -Bria - this is the only phone I could find that works only if the certificate is loaded. Has anybody used other phones with tls and can give me a piece of advice? also, maybe I am not configuring Snom right and that's why it doesn't need a certificate, any ideas? Thanks Catalina
