SIP container custom properties

We can add any of the following custom properties to the configuration 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.

Important: The custom properties are supported as the primary method of configuration. If a custom property is set and then set the corresponding setting in the console, the custom property value is used.

  1. In the console, open the configuration tab for the server...

      Servers | Server Types | WebSphere application servers | server_name | Container settings | SIP Container settings | SIP container | Additional properties | Custom Properties | New

  2. 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.

  3. Click Apply or OK.

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

  5. Restart the server.

We can define the following SIP container custom properties provided with the product. These properties are not shown on the settings page for the container.


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.

Information Value
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.

Information Value
Data type String
Default 10


com.ibm.webspehere.sip.security.digest.ldap.cachecleanperiod

Clean LDAP cache period in minutes.

Information Value
Data type String
Default 120


com.ibm.websphere.sip.security.tai.usercachecleanperiod

Clean security subject cache period in minutes.

Information Value
Data type String
Default 15


com.ibm.ws.sip.key.set

Specifies the key to use for SIP flow token security. When a value is specified for this property, SIP flow token security is automatically enabled.

Information Value
Data type String
Default There is no default value


com.ibm.ws.sip.tai.DisableSIPBasicAuth

Whether to allow basic authentication for SIP.

Information Value
Data type String
Default False


comma.separated.headers

Specifies to the SIP container how the values of a header field are separated and how outgoing messages are serialized. We can specify to separate the header field values by either line separation, so that each header value is on a separate line, or the header values are in the same line and separated by commas. Separation of headers is important in cases where the formatting of proprietary header extensions is not clear to the SIP container and extra configuration is needed so that the container knows how to parse and serialize non-standard headers. Separation of headers is also helpful for formatting both extensions and standard headers on outgoing messages to make them either more human readable, by separating individual headers to multiple lines, or more compact if the message size is an issue.

This custom property affects the parsing of extension header fields, and the serialization of both standard and extension header fields.

The default behavior for the SIP container is to first parse all extension header fields using line separation and then to serialize all header fields using line separation, except for the set of header fields specified to separate with commas.

The syntax of the value of this custom property is:

The number of header name elements is one or more and reflects the name of the header whose processing is being modified. Specifying :on/off/in/out is optional, as the value defaults to on, if not specified. Specify only one of the optional values per header entry. The definitions for each value are as follows:

We can also specify the header_name to use the special wildcard value *, meaning this custom property setting applies for all headers.

During initialization of the application server, if the comma.separated.headers custom property is set, the specified values for this custom property is appended to the default value before the custom property value is parsed. If we have duplicate entries such that there are conflicting definitions in the custom property value, the last definition in the custom property value is used. If we specify * as the header field name, the default separation is applied and overrides all previous definitions.

For example, setting the comma.separated.headers custom property to *:off,My-Header-Field:on produces the following SIP container string value:

This setting causes all header fields to be separated by lines, including the default, with the exception for the My-Header-Field, which is separated by commas.

Examples

  • Use the following comma.separated.headers custom property value to specify that header1 is separated by commas for parsing inbound messages and for serializing outbound messages to the network, and that header2 is separated by lines:

      comma.separated.headers=header1:on,header2:off

    In this scenario, if a SIP message is received with the following values: 

    header1: aaa, bbb,ccc
header2: aaa, bbb,ccc
    then header1 is parsed as three separate headers with the same name and the values of aaa, bbb, ccc as follows: 
    header1: aaa
header1: bbb
header1: ccc
    The header2 is parsed as one string with commas that separate the values of aaa, bbb, ccc.

    When the SIP container serializes, or sends, messages to the network, if the application adds the values aaa, bbb, ccc to each of the headers, then for header1 the outgoing message is serialized as follows:

      header1: aaa, bbb, ccc

    The header2 is serialized as follows: 

    header2: aaa
header2: bbb
header2: ccc

  • Use the following comma.separated.headers custom property value to specify that header1 is separated by commas for parsing incoming messages and separated by lines for serializing outgoing messages, and that header2 is separated by lines for parsing incoming messages and separated by commas for serializing outgoing messages

      comma.separated.headers=header1:in,header2:out

    In this scenario, if a SIP message is received with the following values: 

    header1: aaa, bbb,ccc
header2: aaa, bbb,ccc
    then header1 is parsed as three separate headers with the same name and the values of aaa, bbb, ccc as follows: 
    header1: aaa
header1: bbb
header1: ccc
    The header2 is parsed as one string with commas that separate the values of aaa, bbb, ccc.

    When the SIP container serializes messages to the network, if the application adds the values aaa, bbb, ccc to each of the headers, then for header1 the outgoing message is serialized as follows: 

    header1: aaa
header1: bbb
header1: ccc
    The header2 is serialized as follows:

      header2: aaa, bbb, ccc

  • Use the following comma.separated.headers custom property value to specify that all headers are separated by lines for parsing incoming messages and for serializing outgoing messages to the network:

      comma.separated.headers=*:in

Information Value
Data type String
Default Accept,Accept-Encoding,Accept-Language,Allow,In-Reply-To,Proxy-Require,Require,Supported,Unsupported


DigestPasswordServerClass

Specifies types of user registries that are supported, except LDAP. To configure DigestTAI without the LDAP user registry...

  1. Create a class that implements this interface: com.ibm.ws.sip.security.digest.DigestPasswordServer

  2. Add the following property to the SIP container custom property:

    • Default LdapPasswordServer

  3. Ensure that all users declared by the impl class are declared in the user registry configured for the product security.

Information Value
Data type String
Default impl


disable.failover.suicide

Whether the SIP failover mechanism is active. When this mechanism is active, the SIP container will shut itself down when it detects that all proxy connections are down. If we set this property to true, the SIP failover mechanism is disabled, and the SIP container does not shut itself down even if all proxy server connections are down.

Information Value
Data type String
Default false


enable.system.headers.modify

Whether the application has access to headers that are otherwise restricted.

Information Value
Data type String
Default False


end.of.service.replication

Whether changes are buffered until the thread for a siplet is about to end. If the value is set to true, then each change is buffered until the thread for the siplet is about to end.

Information Value
Data type Boolean
Default true


ignore.ucf.messages.from.proxy

Specifies that proxy detection through UCF is disabled so that the SIP container does not listen to SIP proxy messages that come through UCF. If we set this property to true, only SIP startup messages, which indicate that the front-end proxy server is up and running, and SIP messages that monitor the health of SIP communication lines between a SIP proxy server and the SIP container, are used to monitor communication with a SIP proxy server.

For a proxy server installed in a DMZ, set this property to true because messages that come through UCF are not reliable for proxy servers that are installed in a DMZ.

Information Value
Data type String
Default false


immediate.replication

Whether each change is immediately sent to the Data Replication Service. When true, when replication is issued from a non-SIP container thread, the replication is immediately performed on the calling thread. When false, the changes are buffered, and replication does not occur until all changes are made.

Set this property to true might have a negative impact on performance.

Information Value
Data type Boolean
Default false


javax.servlet.sip.ar.dar.configuration

Location of the default application router (DAR) properties file. The properties file defines the order in which the application router sends SIP requests to applications as described in Appendix C of the JSR 289 specification.

Information Value
Data type String
Default Null


javax.servlet.sip.ar.spi.SipApplicationRouterProvider

Custom application router implementation fully qualified class name as described in section 15.4.2 of the JSR 289 specification. The custom application router implementation class defines the order in which the application router sends SIP requests to applications.

Information Value
Data type String
Default Null

Information Value
Data type String
Default 60


javax.sip.bind.retry.delay

Delay, in milliseconds, between attempts to start the SIP channel if the SIP port is busy with another process during server startup.

Information Value
Data type String

javax.sip.detect.pre.escaped.params

Whether to prevent the container from re-escaping Uniform Resource Identifier (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.

Information Value
Data type String
Default False


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).

Information Value
Data type String
Default True


(WAS v8.5.0.1) message.queue.burst.factor

Burst factor for the message queue.

The burst factor controls how tolerant SIP container managed overload protection (CMOP) is to bursts of high traffic. When the maximum message queue size threshold is reached, the queue becomes overloaded. When the queue is overloaded, the maximum message queue size is multiplied by the burst factor to allow additional messages through without being dropped.

Information Value
Data type Integer
Default 10


on.outgoing.message.replication

Whether changes are buffered until a siplet issues a request.send() or response.send() call. If the value is set to true, then each change is buffered until a siplet issues a request.send() or response.send() call.

Information Value
Data type Boolean
Default false

Information Value
Data type String
Default False


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.

Information Value
Data type String
Default true


sip.jsr289.parse.address

Specifies to use the SIP Servlet Specification 1.1, JSR 289 required format for createRequest() and createAddress() methods.

For transitioning users: The JSR 289 API requires that for any SIP URI containing address parameters, you must enclose the SIP URI in angle brackets. The default behavior of the sip.jsr289.parse.address property is compliant with JSR 289 and correctly parses the address parameter as if it belongs to the SIP address. For example, when the property is set to false, the SIP address, sip:fred@acme.com;param1=1, is converted to <sip:fred@acme.com;param1=1>. When the property is set to true, the SIP address sip:fred@acme.com;param1=1, is converted to <sip:fred@acme.com;>param1=1. trns

Information Value
Data type String
Default True


SIP_RFC3263_nameserver

Whether to allow a SIP URI to be resolved through Domain Name System (DNS) into the IP address, port, and transport protocol of the next hop.

The value of the property is a string containing one or two address and port tuples, where two tuples are separated by a space. The following examples specify a one address and port tuple or a two address and port tuple.

The following example values represent a single tuple.

The following example values represent two tuples separated by a space.

Information Value
Data type String
Default null

Deprecated feature: This custom property is deprecated. Do not use this custom property unless you are running in a mixed cell environment that includes at least one core group containing a mixture of Version 7.0 and Version 6.x processes.depfeat

Mixed-version environment: If we are running in a mixed cell environment, and we have core groups containing a mixture of Version 7.0 and Version 6.x processes, you must 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.

Information Value
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 beneath the maximum weight. This value cannot exceed 10.
