Prevent incoming calls

[reval]

Hi,
I have two MXeIII, "A" with numbering plan 4XXX and "B" with Numbering plan 2XXX. A and B connected through IP/XNET.
A connected to CO lines and uses auto attendant for answering incoming calls.
B does not have any CO trunks but can use some CO lines of A for making outgoing calls.
what can I do on A to prevent B from using CO trunks as incoming trunks ?

e.g. when a external caller hearing auto attendant of A , if he/she dials 4XXX connect to intended destination, but if dial 2XXX blocked.

Thank you in advance for your help

Assuming you are using the regular Embedded VM, this is very simple...

In ESM, go to Voice Mail -> System Settings -> VM Options

In the "Restrict Numbers that begin with..." field, add "2" (without quotes) to the existing settings. This will prevent all calls beginning with the digit 2 from being dialed from the auto-attendant.

See the help on that page for more details, but it is pretty straight forward.
