H323/SIP room based system joins as trusted device or more precisely joins as authenticated user

[JosephNg]

Hi,

For security reason, we hosts internal meeting with feature "sign in to our domain only".  Instead of enabling "required authentication", I can only enable "waiting room" because H323/SIP room based system is always treated as guest.  And this is not ideal as we will always need a host to standby and admit these room based joining.

Does anyone know there is a way to have H323/SIP room based system joins as trusted/authenticated user?  Pairing seems to complicated for end user...

Many thx.
