If you're testing out the tap to call function of your new website – or any other website – and you get the error message, “this website has been blocked from automatically starting a call”, don't worry, it's a security feature of your iPhone – not a problem with your website. You're just running too many tests. For any phone number you click, you get the option of call or cancel. If you hit cancel 3 times then Safari assumes that the website is creating unwanted call requests, and starts creating the message “this website has been blocked from automatically starting a call”. If you hit the Allow button it will reset the block flag and give you the “Call | Cancel” option again.
