Using Click to Call
Installation
Install the CloudTalk Click to Call extension from Chrome's Web Store.
After successful installation, the CloudTalk Click to Call icon will appear next to the address bar in your Chrome browser.
Click the icon and log in using your preferred method:
CloudTalk Account
Google Login
SSO (Single Sign-On)
When you are successfully logged in, click the gear icon to open the CloudTalk C2C settings. You should see your account displayed there.
Automatic Dial
Once active, the Click to Call extension will immediately start scanning your websites for phone numbers including those inside iframes and converts them into clickable links.
Whenever there’s a number that you would like to dial (e.g. a potential client), simply click on the number in your Chrome window and the call will be pasted into your CloudTalk Phone or automatically dialed, depending on settings.
Right Click Dial
On some websites, you may find you need to first open the shortcut menu to dial a found phone number.
Use your cursor to select the number (if necessary).
Open the shortcut menu:
On Mac, use two fingers and press the trackpad, or CTRL + Click.
On Windows, right click.
From the menu, hover over CloudTalk Click-to-Call, and choose one of the available options:
Paste +[number] to CloudTalk Phone: copies the number into the CloudTalk app’s dialer.
Dial +[number] via CloudTalk Phone: instantly starts the call in the CloudTalk app.
Number Settings: Paste or Auto Dial
By default, a clicked number is pasted into your CloudTalk Phone dialer. From there, you can initiate the call by clicking the green dial button.
In Phone Settings, you may change the default behavior to automatically dial clicked numbers.
Select your user icon.
Navigate to Calling > Call automation.
Toggle on Automatically dial Click to call numbers.
Add Numbers to Smart Dialer
When you visit a webpage, the Click to Call extension automatically detects phone numbers and displays them in the CloudTalk C2C popup.
You’ll see a list of detected numbers, along with a counter at the top showing how many were found (for example, "12 numbers found”).
You can:
Select individual numbers to add to your Smart Dialer
Or use Select all to include every number from the page
Once you’ve made your selection, click + Add to Smart Dialer.
All selected numbers will be transferred to your Smart Dialer queue in CloudTalk Phone.
Extension Not Working
The Click to Call extension is designed to detect and convert phone numbers into clickable links automatically.
If numbers do not appear or certain functions are unavailable, it may be due to one of the following reasons:
1. Incorrect number format
Phone numbers must follow the E.164 format, which includes a plus sign (+), an international country code, a local area code, and the subscriber number.
Tip: If a local number without a country code is detected, CloudTalk automatically uses your most recently used country code.
2. Invalid number patterns
The extension filters out text that resembles phone numbers but actually represents something else (for example, dates or timestamps).
3. Restricted website structure
Some pages or web applications use dynamic elements or embedded scripts that limit detection. Although the extension now supports detection inside iframes, certain environments (like sandboxed pages) may still restrict access.
If detection does not work on a specific site, try using the Right-Click Dial option to initiate a call manually.
Deep Links: Specifying an Outbound Number
Some CRMs and internal tools build ct+tel: links that automatically set the outbound number for each call. When an agent clicks the link, CloudTalk opens and dials the contact from the right number, with no manual switching needed.
This is useful when different contacts should be reached from different numbers. For example, if each regional branch has its own phone number, the link can be set up to always use the correct one for that contact.
Note: the links are built by whoever manages your CRM or integration, not by the agent.
Link format
ct+tel:<destination>?from=<outbound_number>
<destination>is the number to dial, in E.164 format (e.g.+15551234567)from=is the outbound caller ID to use, in E.164 format; encode the+as%2B
Example: a CRM stores the link ct+tel:+15551234567?from=%2B421910988342 on a contact record. Clicking it opens CloudTalk and dials +1 555 123 4567 from +421 910 988 342. After the call ends, the agent's outbound number returns to their default.
How it works
The link opens in the CloudTalk Desktop app, which pre-selects the requested outbound number and fills in the destination. If Dial immediately is on, the call is placed automatically. If it's off, you confirm by pressing Call.
The outbound number applies to that one call only. Your default is restored when the call ends.
Requirements
CloudTalk Desktop app only. The operating system routes
ct+tel:links to the desktop app; the browser extension is not involved.The number in
from=must belong to your company and be assigned to your agent account. If it isn't, the call goes out from your default number and a brief notice is shown.
