    Hi @Sammy Mellor ,

    Agree with Leon!

    Teams uses these two protocols to create the network of trusted servers and to ensure that all communications over that network are encrypted. All communications between servers occur over MTLS. Any remaining or legacy SIP communications from client to server occur over TLS.
