SIP container custom properties
We can add any of the following custom properties to the settings for a Session Initiation Protocol (SIP) container.
To specify custom properties for a specific SIP container, navigate to the custom properties page, and then 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 to open the configuration tab for the server.
- From Container settings, expand SIP Container settings, and click SIP container.
- From Additional properties, select Custom Properties > New .
- On the settings page, type the custom property to configure in the Name field, and then 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 SIP container custom properties is provided with WAS ND. These properties are not shown on the settings page for the container.

Set the SIP containerenable.system.headers.modify
Whether the application has access to headers that are otherwise restricted.
Data type String Default False replicate.with.confirmed.dialog.only
Whether to replicate the application session, even when no dialogs are confirmed. If the value is set to false, then the application session is replicated immediately after the session is created. Otherwise, the application session is only replicated when an associated dialog is confirmed.
Data type String Default False com.ibm.sip.sm.lnm.size
Number of logical names in the application server. Each SIP object that can be replicated, such as a SIP session, is associated with a logical name. All objects with the same logical name are replicated to the same back-up container. The proxy can route messages to the correct container using the logical name found in the message. The value must be greater than 1.
Data type String Default 10 auth.int.enable
Auth-int quality of protection (QOP) for digest authentication. Digest authentication defines two types of QOP: auth and auth-int. By default, auth is used. When this custom property is set to True, the highest level of protection is used, which is the auth-int QOP.

Deprecated feature: This custom property is deprecated. Do not use this custom property unless we are running in a mixed cell environment that includes at least one core group that contains a mixture of V7.0 and V6.x processes.depfeat
If running in a mixed cell environment, and we have core groups that contain a mixture of V7.0 and V6.x processes, continue to use this custom property
javax.sip.force.connection.reuse
Whether to force reuse of inbound connections for outbound requests. This custom property is only relevant for stream transports, such as Transmission Control Protocol (TCP) and Transport Layer Security (TLS). Disabling this property causes the container to create a separate connection for outbound requests, even if an existing connection is already established to the same peer address. The connection is automatically reused if the top Via header in the inbound request contains an alias parameter. (http://www.ietf.org/internet-drafts/draft-ietf-sip-connect-reuse-07.txt)
Data type String Default TrueFalse
Deprecated feature: This custom property is deprecated. Do not use this custom property unless we are running in a mixed cell environment that includes at least one core group that contains a mixture of V7.0 and V6.x processes.depfeat

javax.sip.hide.message.body
Specifies to hide message content in logs. Set the value of this property to true to remove the message body text from SIP messages printed in the log files. This property only affects the representation of the messages in log files.
Data type String Default False
Deprecated feature: This custom property is deprecated. Do not use this custom property unless we are running in a mixed cell environment that includes at least one core group that contains a mixture of V7.0 and V6.x processes.depfeat

javax.sip.PATH_MTU
Maximum transmission unit, in bytes, for outbound User Datagram Protocol (UDP) requests. The SIP stack measures the size of a request before sending it out on the UDP channel. If the request is larger than the value specified for PATH_MTU-200 (1300 bytes by default), then the transport is switched from UDP to TCP before transmission. Increase this value to send larger requests over the UDP channel; however, messages might be truncated or dropped. See the RFC 3261-18.1.1 spec for details.
Data type String Default 1500
Deprecated feature: This custom property is deprecated. Do not use this custom property unless we are running in a mixed cell environment that includes at least one core group that contains a mixture of V7.0 and V6.x processes.depfeat
If running in a mixed cell environment, and we have core groups that contain a mixture of V7.0 and V6.x processes, continue to use this custom property

javax.sip.trace.msg.in
Whether to print incoming messages to a system.out file.
Data type String Default False javax.sip.trace.msg.out
Whether to print outbound messages to a system.out file.
Data type String Default False javax.sip.stat.report.interval
Amount of time, in milliseconds, for reporting dispatch and timer statistics to a system.out file. A value of zero indicates no report.
Data type String Default 0 javax.sip.detect.pre.escaped.params
Whether to prevent the container from re-escaping URI parameters that were pre-escaped by the application.
Enable this property provides the application with more control over escaping URI parameters, when calling the javax.servlet.sip.SipFactory.createURI() and the javax.servlet.sip.SipURI.setParameter() parameters.
By default, the container only escapes characters that it must encode according to the RFC 3261 25.1 specification. In some cases, however, escaping additional characters might be required. Due to a limitation in the JSR 116 (5.2.1) specification, the application cannot perform its own escaping. Because of this limitation, attempts by the application to encode URI parameters causes the container to re-encode the percent sign. If the value of this property is set to true, the container cannot re-encode the percent sign.
Set the value to true is not in compliance with the JSR 116 (5.2.1) specification, but provides the application with greater control over URI parameter escaping. APAR PK37192 describes the problem and the workaround.

If running in a mixed cell environment, and we have core groups that contain a mixture of V7.0 and V6.x processes, continue to use this custom property
thread.message.queue.max.size
Maximum number of events allowed in the container threads queue. When this number is exceeded, the proxy server is notified that the container is overloaded and requests for new sessions are not accepted. Instead, the container returns an error message that indicates that the container is temporarily unavailable.
This value represents the total number of messages for all queues and reflects the state of the CPU. When the CPU approaches 100%, the maximum value for this custom property is reached quickly. Configure your system to limit the queue size and prevent the queue from reaching this threshold.
Data type String Default 1000 weight.overload.watermark
Threshold value for the internal weight calculated by the container. When the container calculates the internal weight to be higher than the value specified, an overloaded container becomes available for service again.
This custom property represents a percentage of the maximum internal weight, such as 30 percent when the default value is set. When the high-water mark, or maximum threshold, is exceeded, the container waits until the weight drops below the maximum weight. This value cannot exceed 10.
Data type String Default 3 sip.container.heartbeat.enabled
Whether or not SIP network outage detection is enabled for the SIP container. SIP network outage detection allows the SIP proxy to send keepalive messages to the SIP container if the value of this property is set to true.
If the value is set to false for the SIP container, then this property has no effect on the SIP proxy. However, if the value is set to true for the SIP container, the value should also be set to true for the SIP proxy to ensure that keepalive messages are answered at the SIP container and not presented to the application.
Data type String Default true
