[Kamailio-Users] Phones that support TLS with certificate

Hi!

Just to make clear things - what do you mean with "incoming" - TLS 
connections setup or SIP call flow.

For having incoming TLS connection you would need a client which allows 
to configure a client certificate and acts as TLS server - I am not 
aware of any.

Usually the TLS connection is setup from the client (means the proxy 
acts as TLS server, sending a certificate which is verified by the TLS 
client). Then, once the TLS connection is established, this connection 
is used for outgoing and incoming SIP calls, without any forther 
verification of TLS parameters (TLS certificate is only checked on TLS 
connection setup).

SNOM: I had the same results as you
Eyebeam (probably like Bria): Works fine, uses Windows' certificate store
QjSimple: Should work, you have to provide a file with the CA 
certificates (if not, let me know an I will fix it)

regards
klaus
