• Question 45:

  An administrator uses the Cisco Unified Real-Time Monitoring Tool to investigate recent calls on a Cisco UCM cluster. The SIP trace for an on-net, direct-media call shows two 180 Ringing and two 11 BYE messages. Why are there multiples of each message type in the trace?

  A. The source phone sends a 180 Ringing signal to the Cisco UCM, which sends a 180 Ringing signal to the destination phone. The same process applies to 11 BYE messages.

  B. The source phone must signal to the destination phone that it is ringing, and the destination phone signals back with a 180 Ringing message. The same process applies to 11 BYE messages.

  C. The destination phone signals back to the Cisco UCM that it is ringing, and the Cisco UCM signals back to the source phone.

  D. The calls have an MTP in the call path due to different codec support. The calls are subsequently split into two call legs.

  Correct Answer: A
