The facility is correctly administered and established
with layers 1, 2, and 3. However, no incoming voice calls
can be received. Check that the facility is administered
with the DN provided by the LEC.
If the facility is part of an MLHG, check if the voice
MLHG DN is absent. If the voice MLHG DN is absent,
administer it and rerun the test.
The possible causes for this error are:
■ Incorrect DN/MLHG DN
■ Incoming voice calls are not possible
(Error identified at Incoming Voice Call, Step 2) and
the DN and MLHG DN cannot be verified.
