Numbering Plan

[mariocomputers]

Hello,

I have dutch vox novo office with ISDN30 (HDSL). Can somebody tell me how to set up extension numbers to make them same like end of external number?

Example:

external number starts from +48 58 1234500 up to 1234599
but internal extension starts form 100

I like to make each extension same as last digits of external number
so internal extension will start from 500 and will finish at 599

Is it possible?

Thanks in advance.

You just have to change it in your internal numbering plan
