How to correctly set pattern in inpuy type tel?

Question

HTML

Please tell me how to set the pattern correctly in the input form.

Now so

<input type="tel" name="Phone"  value="" placeholder="Ваш телефон *" pattern="[0-9]*">

But with this pattern, the form is not sent if you enter a phone number through +7, it is also not sent if you enter a number with brackets 1(222)44444444 or spaces.
JS mask libraries do not want to use.
The question is how to add an option other than numbers, spaces, + and brackets?

Answer 1

Keep in the pattern put this check

^(\+7|7|8)?[\s\-]?\(?[489][0-9]{2}\)?[\s\-]?[0-9]{3}[\s\-]?[0-9]{2}[\s\-]?[0-9]{2}$

For every fireman.
