Purpose

The purpose of this article is to explain how to tell if your sandbox is affected by this Salesforce bug, and how to implement the workaround if it is. There is a similar bug that affects only sandboxes that begin with the letter C, but this is outside the scope of this article. More information on this bug can be found here.

Bug Summary

Currently, Salesforce has a known bug that prevents records from opening through OpentCTI and causes CTD to show as disabled on phone fields in a sandbox. This can be resolved by following the steps below to configure an absolute URL in the Salesforce Call Center settings.

This bug is specific to Sandboxes and does not affect Production organizations.

How to See if Your Sandbox is Affected

Open the Tenfold UI in Salesforce.
Find any record in the UI with a button next to it to open the record.
Click the button to open the record.
The record's page should open in Salesforce. If it does not, you will need to follow the steps in the next section to implement the workaround in Salesforce.
Once you're on the record's page, make sure the phone number field is showing as a hyperlink. There will be a phone icon that should not be crossed out.

If the record doesn't open, or the phone icon is crossed out, you will need to add an absolute URL to the call center settings. This can be done by following the instructions in the next section.

How to Implement the Workaround

Right-click inside the Tenfold UI and select Inspect.
Navigate to the Network tab.
Refresh the web browser.
Type "app.js" in the search bar.
You should get two results. Click the second one and navigate to the Headers tab.
Go to the Request URL section and copy the domain. Yours will likely look different than the screenshot below.
Navigate to the Call Center Settings in Salesforce and edit Tenfold Embedded UI.
Paste the base domain you copied into the CTI Adapter URL box and press Save.
