Configuring the Session Initiation Protocol (SIP) container

Configure the Session Initiation Protocol (SIP) container to adjust message response times or set a custom property.

About this task

Use the administrative console to configure SIP container settings. Complete the following steps to find and configure the SIP container settings.

Procedure

  1. Start WebSphere® Application Server.
  2. From the administrative console, click Servers > Server Types > WebSphere application servers > server_name.
  3. From Container Settings, expand SIP Container Settings, and click SIP Container.
    Select the container settings that you want to change.
    • From General Properties, you can configure session, message, and response time maximums. See Session Initiation Protocol container settings and SIP container custom properties.
    • From Additional Properties, you can define custom properties, manage transport chains or inbound channel settings, or configure the session manager.
  4. After configuring the SIP container, click Apply to save the changes.
  5. Restart WebSphere Application Server.

Results

Changes to the SIP container settings take effect after you restart WebSphere Application Server.
Avoid trouble: As the number of SIP containers grow in a deployment, the larger the heap settings need to be on the SIP proxy server. For example, a deployment of 20 containers requires a minimum heap size of 60 MB, so a -Xmo60m parameter should be added to the Generic JVM arguments field on the Java™ virtual machine panel of the admin console. However, a deployment of 70 containers requires a larger value such as 200 MB (-Xmo200m). See the Java virtual machine settings for more information about Generic JVM arguments.
