Separation of telephone numbers by a dot

Question

Hello,
Am still newbie in coldfusion.
I have a telephone number of 12 digits, for e.g, [phone].
Now I have to replace the country code by 0,i.e, +33 to 0. I have already done that.
My problem is how to separate these 10 remaining numbers and put a dot in between each 2 numbers like 12.34.56.78.90 and at the end join the country code like 0.12.34.56.78.90
I was thinking of doing a Len() of the numbers and then separate them by a dot but unfortunately I don't know how to do it.
Can anybody help me please ?
Thanks in advance.

<cfset dotted_reverse_telno = "">
<cfset telno = "01234567890">
<!---Reverse the tel number --->
<cfset reverse_telno = reverse(telno)>
<!---Run through the digits in the reversed number, adding a dot after every 2 digits --->
<cfloop from="1" to="#len(reverse_telno)#" index="n">
    <cfif n mod 2 EQ 0>
        <cfset dotted_reverse_telno = dotted_reverse_telno & mid(reverse_telno, n, 1) & "." >
    <cfelse>
        <cfset dotted_reverse_telno = dotted_reverse_telno & mid(reverse_telno, n, 1)>
    </cfif>
</cfloop>
<!---Reverse the result --->
<cfset dotted_telno = reverse(dotted_reverse_telno)>
<cfoutput>#dotted_telno#</cfoutput>
