You can add the following custom properties to the configuration settings for the Session Initiation Protocol (SIP) UDP transport channel.
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.
Specifies whether you want to make the UDP client-side interface active without actually receiving packets over it.
Unless you add this property to your SIP proxy server settings, the SIP proxy server cannot send UDP messages outbound because it does not have an active client-side interface. Typically, the SIP proxy server sends a UDP message to the client-side interface to activate the interface. If a message cannot be sent, SIP messages are sent from the container to the proxy server, but are then dropped.
Information | Value |
---|---|
Data type | Boolean |
Default | false |
Specifies whether you want the message body included in the SIP proxy server trace messages. Starting with Version 7.0.0.13, 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 |
Data type | string |
Default | Authorization,Proxy-Authorization |
Specifies the 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.
Setting 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 |
Specifies the 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 |
Specifies the 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 |
Specifies the 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.
