Click to Dial Using Mitel One Web Application

Pre-requisites

You must set the following prerequisites before you can use this feature:

1. Set your preferred browser as the default calling app (TEL URI) in your device.
   Note: If you want the Mitel One Progressive Web Application (PWA) to be used to place a call when you use the Click to Dial feature, you must set Google Chrome or Microsoft Edge as the default calling app. This is because PWA is supported only on these browsers.

   The option to change the default app for calling is specific to the operating system in which you have deployed the extension. Click the following links for instructions on changing the default calling app specific to your operating system.

   • Windows
   • Mac OS

   Restart your browser for the new configuration to become active.

2. You must grant permission for the application to be the default handler to place calls to all the telephonic links in your browser. To do this, perform the following steps:
   1. In the address bar of your browser, click the icon. In the Allow one.mitel.io to open all tel links? prompt dialog box that opens, select the Allow option and click Done. If you choose to Deny or Ignore this prompt, you will not be able to use the Click to Dial feature.
      
      

      

      
      
   2. In the Allow one.mitel.io to open all web+mowa links? prompt dialog box that opens, select the Allow option and click Done. If you choose to Deny or Ignore this prompt, you will not be able to use the Click to Dial feature.
      Note: Refresh your browser if the browser does not present this prompt message.
      
      

      

      
      

      You can now use the Click to Dial feature to call the phone numbers in your browser.

      To change the handler permission settings, follow instructions specific to your browser.

      • Google Chrome: Menu > Settings > Privacy and security > Site settings > Additional permissions > Protocol handlers
      • Microsoft Edge: Menu > Settings > Cookies and site permissions > Site permissions > Protocol handlers
      • Mozilla Firefox: Menu > Options > General > Applications
      Note: If any user is previously registered with any other tel URI handler (For example, http://office.mitel.io/) in their browser, they will need to remove the old handler, log out and then log in again to the application, and click Allow in the Allow one.mitel.io to open all tel links? prompt dialog box.

      
      

      

      
      

      If Click to Dial still does not work on the application, then the user will need to remove one.mitel.io from the Protocol handlers section in the Google Chrome settings, refresh the application, and click Allow in the Allow one.mitel.io to open all tel links? prompt dialog box.

3. You must allow the application to display notifications. For more information, see Permissions and Notifications.
4. You must turn off or disable all other Tel: URI features in the browser.

Using the Click to Dial feature

This section describes how to use the Click to Dial feature in the application.

1. From the phone numbers available in websites, documents, or calendar invitations click the phone number to which you want to place a call.
   
   

   

   
   

   Alternately, type tel:xxxxxxxx (phone number) in the address bar of your browser and press ENTER to dial the telephone number.

   
   

   

   
   
   Note: When you dial a number, a country code is added to it as a prefix by default. The country code depends on the default language set in your browser. For example: If the default language of your browser is set to English (United States), when you dial 345xxxxxxx, the country code of UK (+1) will automatically be added to the number and the application will dial +1345xxxxxxx.
