Hello all,
encryption makes sense,
but I don´t know how to force Messenger to use encryption.
I´m pretty sure, that I can do this with a GPO, but I don´t know which value
is responsible for that.
I found:
"Require SIP high-security mode"
"Specify encryption for computer-to-computer audio and video calls" .
I set both to enable, but when I trace a voice conversation between two
messenger users, the UDP/RTP packets seems not to be encrypted (Codec 111 is
shown, which might be SIREN.).
Can you give me a definition of these two options?

I´m using TLS for encryption of the signalling and a LCS2003 .

Thanks for help !
