Translation rules problem

Crunchyhippo

I need some explanation with this problem:

rule 1 /\(.*\)3828$/ /\13434/

Dialed string is 2234853828

The replaced string value says 2234853434

---

The 3828 in the dialed string is missing; is this because in the rule, the 3828 is followed by the "$" sign? If so, does a $ sign erase everything in that number slice - so the 3828 at the end of the dialed string would disappear?

I'm also having trouble with (.*) Here, would the "*" have to be one or more of the same digit as "."? So if it was applied to, say, 222134, the 222 would be replaced with something else?

The DOT/ASTERISK is a wildcard combination (from the chart I linked in your previous translation rules question post)

Any digit followed by none or more occurrences. This is effectively anything, including null.

Looking at the match --
match a string that ends with 3828
and save any and all digits preceding the 3828 in match save string 1

The Replace says --
The \1 says to put the 1st saved string from the match here -- so that's the 223485
Then append 3434 to the end

If you tried this with 3828 as the input dialed string, you'd get 3434 as the result string.
