• Question 337:

  Which configuration on Cisco Unified Communications Manager is required for SIP MWI to work?

  A. The line partition must be inside the inbound CSS assigned to the CUC SIP trunk.

  B. The line partition must be inside the rerouting CSS assigned to the Cisco Unity Connection SIP trunk.

  C. Set the "Enable message waiting indicator" on the part group.

  D. Assign a MWI extension on the mailbox.

  Correct Answer: A

  The line partition must be inside the inbound CSS assigned to the CUC SIP trunk. This ensures that the SIP MWI messages are sent to the correct destination.

  The other options are incorrect because:

  Assigning an MWI extension on the mailbox is not required for SIP MWI to work. The line partition does not need to be inside the rerouting CSS assigned to the Cisco Unity Connection SIP trunk.

  Setting the "Enable message waiting indicator" on the port group is not required for SIP MWI to work.

• Question 338:

  After an engineer runs the utils ntp status command on the Cisco Unified Communications Manager publisher, the stratum value is 16. Which issue can the Cisco Unified CM cluster experience?

  A. Unified CM sends an NTPV4 packet.

  B. Database replication is not synchronized on the Unified CM nodes.

  C. The cluster loses access to port 124 at the firewall.

  D. The date/time group on all phones defaults to the time zone of the engineer.

  Correct Answer: B

  16 is a invalid stratum value that means "this server is not considered a time provider". The stratum can be invalid for various reasons, the most common of which is that the "time provider not synchronized", the "configured source does not exist", or the "ntp server not running". CUCM can communicate with the NTP server on Port 123
