Configuring Port Ranges on the SCOPIA XT Series
This section provides instructions of how to configure the following port ranges on the SCOPIA
XT Series:
Configuring the TCP Port Range for H.225.0/Q.931/H.245/SIP on the SCOPIA XT
Series......................................................................................... page 83
Configuring the UDP Port Range for RTP and RTCP on the SCOPIA XT Series....... page 84
Configuring the TCP Port Range for H.225.0/Q.931/H.245/SIP on the SCOPIA XT Series
The SCOPIA XT Series has designated TCP ports 3230-3248 for the following:
H.225.0: An H.323 protocol that specifies the messages and procedures used by
gatekeepers.
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.
You can configure the port range by setting the base port, which is the lower end of the port
range (if, for example, port 3230 is busy).
