Dial Plan- Prefix for internal dialing

[dig1234]

Is there a way to setup a stripLead on an internal route?

I am setting up an ATA to replace a POTS line.  It needs it to be direct dial (no 9 prefix). I have created a simple table shown below. Problem is, currently there is no way for user to dial internal. Idea is to use a prefix 0 for internal calls. [We don't need 0 for operator. ] Here is the current Table:

/                  Id Entry  Digits       Min Max Class           Prio Route
/                  -- -----  ------------ --- --- -------------   ---- -----
TableEntry Create   6     2  1             11  11 LongDistance       0     2
TableEntry Create   6     3  2              7  7 Local              0     2
TableEntry Create   6     4  3              7  7 Local              0     2
TableEntry Create   6     5  4              7  7 Local              0     2
TableEntry Create   6     6  5              7  7 Local              0     2
TableEntry Create   6     8  6              7  7 Local              0     2
TableEntry Create   6     9  7              7  7 Local              0     2
TableEntry Create   6    10  8              7  7 Local              0     2
TableEntry Create   6    11  9              7  7 Local              0     2
TableEntry Create   6    21  911            3   3 Emergency          0     2

I would like to create a new route like this:

TableEntry Create   6    12  0              4  4 Local              0     9

DestinationRouteEntry Create     9     1  0    <<<<*DOESN'T WORK*

DestinationRouteOperation Create     9    1      1 stripLead  1

Problem is DestinationRouteEntry wants an extension list but this is an internal route!

Bottom Line: How can I use StripLead on an internal route? Or is there a better way to accomplish this.

Hope this makes sense, Any ideas?

Thanks, Dan
