Troubleshooting Cloud PBX

Find the issue you see in the table below, then open its article for the full fix. Most Cloud PBX issues come from IP access rules, Click2Call setup, or browser settings, so start with the quick checks.

Check these first

Run these checks before you open an article. They solve many sign-in and integration issues.

Make sure the IP addresses you use are allowed in your PBX's Access Control Lists (ACL): the Web ACL for signing in, and the Click2Call ACL for requests from your Customer Relationship Management (CRM) system. See PBX IP ACL Settings.
Make sure you set up Click2Call as described in Getting Started With Click2Call. If you recently moved to a new CRM, see How Can I Set Up Click2Call After Switching to a New CRM?.
Use an up-to-date Chrome browser, and allow it to access your microphone.
