[Asterisk-Users] How can i convert number with exten

[Johannes van Hulst]

I am looking for a way to convert numbers so that I can use one standard for
all the providers.

For example
I would like to dail 00 31 20 1234567
And that convert to 0011 31 20 1234567 so that my VS provider understands
it.

How can I remove the 00 and replace it with 0011.

Greetings Han
