SIP UDP transport channel custom properties
We can add the following custom properties to the configuration settings for the 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.
- In the admin console, expand Servers > Server Types > WebSphere application servers > server_name
or Servers > Server Types > WebSphere proxy servers > proxy_server_name
to open the configuration tab for the server.
- 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.
- From Additional properties, select Custom properties > New .
- 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.
- Click Apply or OK.
- Click Save on the console task bar to save the configuration changes.
- Restart the server.
The following list of UDP transport channel custom properties is provided with the product. These properties are not shown on the settings page for a UDP transport channel.
- hideMessageBody
- hungThreadTimeout
- hideMessageHeaders
- receiveBufferSizeChannel
- receiveBufferSizeSocket
- sendBufferSizeSocket

hideMessageBody
Whether you want the message body included in the SIP proxy server trace messages. By default, the trace messages do not include Authorization or Proxy-Authorization headers. If you also do not want the message body to appear in the trace log, add this custom property to the settings for the SIP inbound channel (SIP 1) and set the property to true.
Data type Boolean Default false
hideMessageHeaders
Specifies one or more of the SIP message headers that you do not want to appear in the SIP proxy server trace messages. If you specify multiple headers, use a comma to separate the header names. By default, the trace messages do not include the Authorization, and Proxy-Authorization headers. If you specify a value for this property, include the Authorization, and Proxy-Authorization values to prevent these headers from being displayed. For example, if you specify hideMessageHeaders=Via, only the Via header does not appear in the trace messages.
To prevent the Via, Authorization, and Proxy-Authorization headers from appearing in the trace messages, specify hideMessageHeaders=Via,Authorization,Proxy-Authorization.
Data type string Default Authorization,Proxy-Authorization
hungThreadTimeout
Amount of time you want the SIP proxy server to wait for one of it's UDP threads to be returned before reporting an error.
By default, the SIP proxy server reports an error if any of its UDP threads are not returned to the pool in 30 seconds. If you want to change the length of time that the SIP proxy server waits for a UDP thread to be returned, use this property to specify, in seconds, the length of time you want the SIP proxy server to wait.
Set this property to 0, indicates that you want the SIP proxy server to wait for 30 seconds before reporting an error.
Data type integer Default 0
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.
Data type String Default 1024000
receiveBufferSizeChannel
Value, in bytes, for the maximum size of an incoming UDP packet, which is the size of the receive buffer that is allocated by the UDP channel.
Data type String Default 65535
