Call Center Settings

For the demo adapter to work properly, you might need to update some settings.

General Settings

If you don’t see the softphone in your app or the softphone doesn’t launch, verify the CTI adapter URL is correct. To edit the CTI Adapter URL:

  1. In your Salesforce org, go to Setup and enter Call Centers in the Quick Find box, then click Call Centers.

  2. Click Edit next to the Demo Call Center Adapter and make sure that the CTI Adapter URL points to the absolute path of the Visualforce page called demoAdapterPage. The URL must include the Lightning path and your domain. For example, both of the following URLs are valid:

Note that if you are using a page from a managed package, the url will look like

When the absolute URL doesn't work, open the chrome inspector look for an error like: 'Blocked a frame with origin "" from accessing a cross-origin frame'. This is a clue that your CTI Adapter URL must start with or whatever the error said that is blocked.

  1. Click Save

To change the phone number used to simulate incoming calls, edit the Simulated Incoming Phone Number field on the Demo Call Center Adapter page in Setup. The default phone number used to simulate incoming calls is 415-555-1212.

CTI Provider Settings

Want to make real calls with this demo adapter? We’ve made this super easy to do with Twilio. To integrate with Twilio, complete the following steps:

  1. Install the Twilio Salesforce Helper Library in your org. You’ll need the following information:
  • CTI Provider—The name of the internal Apex class that implements SoftphoneProviderHelper.SoftphoneProvider, and has the code implementing makeCall(), such as DummyProvider, TwilioProvider or your own provider implementation.
  • Provider Account—Provider account ID.
  • Provider Auth Token—Provider authorization token.
  • Provider Caller Number—The phone number from where the call originated. This is the From number. By default, this is 415-555-5555.
  1. In your Salesforce org, edit the Apex class SoftphoneProviderHelper. In the inner class TwilioProvider, uncomment the code related to Twilio.

  2. Optionally, modify the default task page layout for your call center users. For every call made with the demo adapter, the call log creates a task. To see the call-related fields on these tasks, assign the page layout Demo Call Task Layout to your call center users. For more information, see Assigning Page Layouts in the Salesforce Help.
