Hi Barnabas,
1. So you mean now when you use INBAND, it works?
2. About RFC2833, sorry currently we do not have plan to support this, could you let us know does this issue will affect your using?
Thanks.

Hi Administrator,

1- Yes, it works now with INBAND. Thank for your advise.
2- We will deploy it although programming of the server will take manual effort.
