Audio [UDP], Video
[UDP] Define the ports used for audio and video channels.
After you enter the beginning of the range, the
system automatically fills in the end of the assigned
range.
If the first audio port is 49182, and the number of
audio ports per call is two, the total number of
required ports for six simultaneous calls is 12.
Therefore, the last port number in the range is 49193.
Data [TCP] Define the ports used for transferring data packets:
file transfer, whiteboard, and application sharing. The
recommended port range is 49152 to 65535. After
you enter the beginning of the range, the system
automatically fills in the end of the assigned range.
FECC [UDP] Define the ports used for FECC. After you enter the
beginning of the range, the system automatically fills
in the end of the assigned range.
When fixed ports are exhausted
Allocation ports
dynamically Select this option to allocate any of the available
ports in the firewall to calls that exceed the number of
predicted simultaneous calls. These ports may not be
secured.
Reject Set the system to reject any request to open
additional ports and the call will be rejected.
If the volume of simultaneous calls exceeds the
specified number of calls and there are no available
ports in the firewall to handle the call, it is rejected by
the network server.
