Initiating a Video Conference From Your 150 MXP
Your TANDBERG 150 MXP may be used 
to initiate video conferences w ith several 
participants, provide d that: 
All parties to be involved are ava ilable 
through H.323. 
You are connected to an MCU (Multi-
Conference Unit) support ing this.
Your TANDBERG 150 
MXP is set up to allow 
the use of external Multiway. This is set u p 
by your administrator and is descr ibed in 
the Administrator’s Guide.
Since the call transfer feature m akes use of 
SIP and the conference initia lization feature 
makes use of H.323, the two features ca nnot 
be combined in a single session!
