Corrective Action
Possible causes for this error are:
Outgoing voice calls are not possible.
(Error identified at Outgoing Voice Call Test,
Step 4)
Incoming voice calls are not possible.
(Error identified at Incoming Voice Call Test,
Step 2)
If MLH is expected, the possible causes are:
— CO provisioning does not allow incoming
voice calls, but either the DN or MLHG DN
has been verified to be correct.
IF MLH is not expected, the possible cause is:
— Provisioning on the facility does not allow
incoming voice calls.
Additional call offering is provisioned
Additional call offering allows a voice call to be
presented to a busy facility without either party
recognizing the condition. Therefore, this
condition cannot be detected by manual
testing. This cause is valid if incoming voice
calls can be received successfully.
Features provisioned
Supplementary features such as transfer and
conference are provisioned at the CO. This
condition cannot be detected by manual
testing. This cause is valid if incoming voice
calls can be received successfully.
