Once there you will see boxes for Username and Password.
Your username will be your-extension@domain-name. You can get the domain name from your quick start guide that you received from the Telephone Administrator at your company, or directly from your Telephone Administrator. This will not match your email address.
Example: 1234@example
Your password, by default, will be your extension twice. Once logged in to the portal you will be able to change this.
Example: 12341234
After you have entered your credentials, simply click the Log In button.
