Ok so you need to make sure your provider allows this feature , over here in the UK we need to have the numbers we want to send active on the circuit , so we would order a block of DDI numbers and match the extn to replicate the last 3 or 4 digits of the DDI, then in the sysetm you need to manipulate the public unknown numbering tables to set what number a extension sends when dialing out.
