2 Modify the following fields:
○ Fixed Ports Check this option to manually define the port ranges or to limit the number of
ports to be left open. Leave this option cleared if you are defining a Network Service for local
calls that do not require configuring the firewall to accept calls from external entities. When
cleared, the system uses the default port range and allocates 4 RTP and 4 RTCP ports for media
channels (Audio, Video, Content and FECC).
Note: Enabling ICE
When ICE Environment is enabled, eight additional ports are allocated to each call.
○ TCP Port from_to_ These fields display the default settings for port numbers used for
signaling and control. To modify the number of TCP ports, enter the first and last port numbers
in the range. The number of ports is calculated as follows: Number of simultaneous calls x 2
ports (1 signaling + 1 control).
○ UDP Port from_to_ These fields display the default settings for port numbers used for audio
and video.
» To modify the number of UDP ports in Card Configuration Mode, enter the first and last port
numbers in the range. The number of ports is calculated as follows:
Number of simultaneous calls x 8 ports (2 audio, 2 video, 2 Content, and 2 FECC).
» To modify the number of UDP ports in MPM+/MPMx Card Configuration Mode, enter the
first and last port numbers in the range, and the range must be 1024 ports. When ICE
environment is enabled, the range must be 2048 ports.
Caution: Specifying Port Ranges
If you do not specify an adequate port range, the system accepts the settings and issues a
warning. Calls are rejected when the MCU's ports are exceeded.
Configuring QoS Settings
This section shows you how to configure Quality of Service (QoS) settings in the RMX Management
pane. QoS is important when transmitting high bandwidth audio and video information. The following
QoS features can be measured and guaranteed:
• Average delay between packets
• Variation in delay (jitter)
