Configuring the TCP or UDP Port Range on the SCOPIA XT Series
You can configure the TCP or UDP port range by setting the base port, which is the lower end
of the port range (if, for example, port 3230 is busy).
The SCOPIA XT Series uses dynamic TCP ports 3230-3248 for the following:
•
H.225.0: An H.323 protocol that specifies the messages and procedures used by
gatekeepers to set up calls.
•
Q.931:A telephony protocol used for establishing and terminating the connection in H.323
calls.
•
H.245: A Control Protocol used for multimedia communication; enables transferring
information about the device capabilities, as well as opening/closing the logical channels
that carry media streams.
•
SIP: A signaling protocol used for creating, modifying, or terminating multimedia
connections between two or more participants.
The SCOPIA XT Series uses dynamic UDP ports 3230-3248 for enabling real-time H.323 and SIP
media, including audio, video, and H.224/data (RTP), and media control (RTCP).
