How to delete first character from regex [JS]

I managed to find and replace phone numbers with a very simple Java Script but need to delete the first character as easy as possible. Could anyone please give me an hint?

function cleanPhoneNumbers() {
    document.body.innerHTML = 
        document.body.innerHTML.replace(
            /\(?(0[0-9]{2,4})\)?\-?\/?\ ?[-. ]?([0-9]{7})/g,
            "<a href='tel:+49$1$2'>$1-$2</a>"
        );
}
</script>

Easy, just modify your existing code so it looks like this...

<script type="text/javascript">
function cleanPhoneNumbers() {
    document.body.innerHTML = 
        document.body.innerHTML.replace(
            /\(?(0[0-9]{2,4})\)?\-?\/?\ ?[-. ]?([0-9]{7})/g,
            "<a href='tel:+49$1$2'>$1-$2</a>"
        ).substring(1);
}
</script>

This updated code uses javascript substring command, the number 1 states where to start the string. 0 would be the whole string, 1 starts after the first character.
