You could make it a hunt group.
If you use a loopstart trunk. (A line that would normally come from an incumbant telco. instead of an Extension)
Put an FXS card in instead of an FXO.
when you dial the access code ie 9 You will get dialtone from the FXS
You then dial the Number. and you get processed through * , through sip, then to your endpoint.
Again you want to use an FXS card instead of an FXO.
It makes it alot easier to access. if you wanted to make your extensions a longer distance you would then want to use an FXO.
