Route call to local sub
The originating switch sends an IAM to the donor switch with NOA=3 and DN=7034841000.
In the DN2subscriber table on the donor switch, STATUS=ASSIGNED and LNP-TRIGGER=Y.
Since the LNP-TRIGGER=Y, the donor switch performs a query.
The query does not return a RN to the donor switch, indicating that the subscriber is not yet ported

The donor switch routes the call to the local subscriber.
