We have OXE and ICS messaging , previously it was working fine.

Now, when the OX E user dials the external VM dir number , it gives the prompt , the number dialed is not authorised.

In SIP traces , the call fails giving global failure.

If anybody can share the steps to configure the ICS 8440 as External VM to OXE users, that will also be helpful.
I will try to check and isolate the problem .
