Hello,

Thank you for your detailed response.

The reason I omitted those details is because I was not aware of them.
My initial question arose precisely because I couldn't find clear
information on whether it was possible to make direct calls using TLS
in Linphone within a LAN network.

I would like to continue exploring the topic of direct calls using
TLS. Could you please indicate if there is documentation available on
this subject?

Best regards,

A.
