PBX-1 modifies and routes the call to PBX-2 through a private IP network according to the ARS
programming of PBX-1.

The IP network transmission cannot be completed successfully and the call is rerouted via a public CO
line to the outside party "012-345-1011".

private IP network according to the ARS programming, and the call will not be completed.
