Refer to the exhibit. Which troubleshooting action must be performed to investigate the issue?

  • A Check the calling privileges of the line and device.
  • B Restart the Cisco CallManager service on all nodes.
  • C Reset the destination SIP trunk in Cisco UCM.
  • D Reset the phone being called in Cisco UCM.
Explanation

A SIP 404 Not Found with Q.850 cause 1 indicates that the dialed destination cannot be resolved or routed. In Cisco Unified Communications Manager, a calling search space or partition mismatch can prevent the calling endpoint from reaching the called directory number; checking the calling privileges assigned to the line and device investigates that routing-access condition.
