We can add the following custom properties to the configuration settings for the Session Initiation Protocol (SIP) UDP transport channel.

To specify custom properties for a specific UDP transport channel, navigate to the custom properties page, and specify a value for the custom property.

The custom properties are supported as the primary method of configuration. Therefore, if a custom property is set and then you set the corresponding setting in the admin console, the custom property value is used.

  1. To open the configuration tab for the server...

    Servers | Server Types | WebSphere application servers | server_name or Servers | Server Types | WebSphere proxy servers | proxy_server_name

  2. From SIP container settings or SIP proxy server settings, expand SIP container transport chains or SIP proxy server transports, and click UDP specific chain, and select UDP inbound channel.

  3. From Additional properties, select Custom properties > New.

  4. On the settings page, type the custom property to configure in the Name field, and type the value of the custom property in the Value field.

  5. Click Apply or OK.

  6. Click Save on the console task bar to save the configuration changes.

  7. Restart the server.

The following list of UDP transport channel custom properties is provided with WAS ND. These properties are not shown on the settings page for a UDP transport channel.

receiveBufferSizeSocket


Value in bytes for the lower level datagram buffers. This is the size of the DatagramSocket receive buffer (SO_RCVBUF) on any inbound User Datagram Protocol (UDP) channel.

Use this property to buffer multiple packets in the DatagramSocket layer. If the value of the property is too small, then packets might be lost if the server is overloaded. If the value is too large, then the packets might be delayed.

Data type String
Default 1024000

sendBufferSizeSocket


Value, in bytes, for the lower-level datagram buffers, which is the size of the DatagramSocket send buffer (SO_SNDBUF) on any inbound UDP channel.

Use this property to buffer multiple packets in the DatagramSocket layer. If the value of the property is too small, then packets might be lost if the server is overloaded. If the value is too large, then the packets might be delayed.
