Need to be able to treat local numbers differently

[tipichris]

In thunderbird TB I have stored the numbers in international code. Example: +49 123 4567 I configured TBDialOut to replace "+" with "00". Everything seem fine, but my providers disallows to dial national calls with 0049123456. What is allowed is to dial 0123456 So what I need is the possibility to replace "+49" with "0"

As there are many different possible requirements, depending on how numbers have been recorded in the address book, how different providers expect numbers to be presented etc, it would be useful to have a flexible, configurable substitution mechanism, possibly supporting regular expressions.
