Your company has recently installed a Cisco Unified CallManager cluster and a Cisco Unity voice
mail platform. You have received complaints from users that the red MWI light never comes on,
even when there are new voice-mail messages in the voice mailboxes. Which two steps must be
taken to resolve this issue? (Choose two.)

A.
Verify, using the Port Usage tool, that the ports dedicated to MWI on/off are not over-utilized.
Add another dedicated port if the current port is over-utilized.

B.
Verify that the MWI on/off numbers are unique within the Cisco Unified CallManager cluster dial
plan. If they are not, change the MWI on/off numbers in the Cisco Unified CallManager cluster so
they are unique and configure the Cisco Unity server so they match.

C.
Ensure that the number of ports licensed for the Cisco Unity server is greater than or equal to
the number of configured ports.

D.
Verify that the calls are being sent to the correct ports on the Cisco Unity server. If they are
being sent to the incorrect ones by the Cisco Unified CallManager cluster, correct the values in the
cluster.

E.
Verify that the same numbers are being used for MWI on/off in both the Cisco Unified
CallManager cluster and Cisco Unity server. If they are different, change the Cisco Unity server to
match the Cisco Unified CallManager cluster.
