• Question 90:

  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.
