Thanks Cheers Rob,

Protocol error messages are no longer displayed when adding the bc2025.pem
file, but entering the command "kamcmd dispatcher.list | egrep" URI | FLAGS
"shows us:

  URI: sip: sip.pstnhub.microsoft.com; transport = tls
                                         FLAGS: IP
                                         URI: sip:
sip2.pstnhub.microsoft.com; transport = tls
                                         FLAGS: IP
                                         URI: sip:
sip3.pstnhub.microsoft.com; transport = tls
                                         FLAGS: IP

Is there something else that needs to be done?

Atentamente
