Configuring Tcp/Udp Ports - Codec Tieline ViA User Manual

31.12 Configuring TCP/UDP Ports

In TCP and UDP networks the codec port is the endpoint of your connection. These network ports
are essentially the doorways for systems to communicate with each other. For example, several
codecs in your studio may use the same public static IP address and unique port numbers can be
used to route audio to each codec.
For two codecs to connect, they need to be configured with matching port numbers. In most
situations you should consult your organization's IT professional if there is a need to adjust codec
port settings.
Adjusting Port Numbers
Reasons for adjusting the port setting on your codec include:
· Creating a safe path through an organization's gateway and firewall configuration.
· Another IP device is already using a codec's port number.
· More than one studio codec is in use and each codec requires a different port number.
Tieline Codec Default Port Settings
By default, the codec uses a TCP session port to send session data and a UDP port to send audio
for each connection. The session port is configured to use the TCP protocol because it is the most
likely protocol to get through firewalls – ensuring critical session data (including dial, connect and
hang-up data) will be received reliably. The same session port can be shared for multiple
connections to one codec but a unique audio port needs to be assigned for each IP connection.
The default session and audio port settings in Tieline codecs are outlined in the section
the Codec at the
and troubleshooting IP connections.
The following sections describe how to adjust port settings for Tieline session data and audio ports.
