When this happens
An older Open CTI exercise references a demo package or call center that is not available in the playground.
What to check
Demo package availability can change, and an installed package and a configured call center are separate prerequisites.
Troubleshooting steps
- Use the current module’s package link and compatible learning org, not a third-party archived package.
- Check Installed Packages for installation success and any error details.
- Inspect Setup → Call Centers for the required definition.
- Check call center user assignments and app utility or softphone configuration required by the exercise.
- If the official package link is unavailable, contact Trailhead support with the unit URL and error instead of installing unknown software.
Verify the result
The prescribed demo package, call center definition, and user configuration are present.
Based on a community learning issue discussed with Vishal. Guidance reviewed October 5, 2026; org setup, module instructions, and release versions can differ. These steps are checks to perform, not a claim that your org has been tested.
