yes, you could if set 11-15-09 up. but I am not sure whether anybody has used that code.

What I mean is that we have numbering plan, also we have incoming group, department group, ACD group... but they are different.

For example, extension or VE could be in 22-11-02, but not in 22-11-05/06 transfer targets, they have different values,1-100 for incoming group, 102 for VM, 201-264 for department group, 400 for valid extension number, 401 for DISA, 501-599 for DISA/VRS message, 1000-1999 for Speed dial.

you can't put an extension into transfer target, or put a IRG into target.
