Click OK to complete the flag definition.
5 When prompted, click Yes to reset the MCU and implement the
changes to the system configuration. After system reset the RMX can
register to the OCS server and make SIP calls.
Sometimes the system fails to read the *.pfx file and the conversion process
fails, which is indicated by the active alarm "SIP TLS: Registration server not
responding" and/or "SIP TLS: Registration handshake failure". Sending *.pfx file
again, as described in this procedure and then resetting the system may resolve
the problem.
In some configurations, the following flags may require modifications

Value and Description
Default value in Microsoft environment:
NO.
When set to NO, video resources that
were allocated to participants remain
allocated to the participants as long as
they are connected to the conference
even if the call was changed to audio
only. The system does not allocate the
resources to other participants ensuring
that the participants have the appropriate
resources in case they want to return to
the video call.
The system allocates the resources
according to the participant's endpoint
capabilities, with a minimum of one CIF
video resource.
When this flag is set to YES, video ports
are dynamically allocated or released
according to the in the endpoint
capabilities. For example, when an audio
Only call is escalated to Video and vice
versa or when the resolution is changed.
