Cisco CCNP Collaboration 300-815 Questions & Answers

• Question 151:

  Refer to the exhibit.

  

  In an active SIP call between phone user A and phone user B, phone A initiates a call transfer to phone user C. What are two results from this action? (Choose two.)

  A. Phone_A sends a SIP-REFER message to the Cisco Unified Communications Manager with Phone_C information in the Refer-To section.

  B. Phone_B sends a SIP-REFER message to the Cisco Unified CM with Phone_C information in the Refer-To section.

  C. As soon as Phone_A presses the Transfer button for the first time, Phone_B hears the MOH and the MOH audio is chosen from Phone_B User Hold MOH Audio Source settings.

  D. As soon as Phone_A presses the Transfer button for the first time, Phone_B hears the music on hold and the MOH audio is chosen from Phone_A Network Hold MOH Audio Source settings.

  E. As soon as Phone_A presses the Transfer button for the first time, Phone_B hears the MOH and the MOH audio is chosen from Phone_A User Hold MOH Audio Source settings.

  Correct Answer: AD

  User hold: With a user hold, a user presses the Hold button on a phone to explicitly place the caller on hold. If Phone A and Phone B are having a conversation, and the user of Phone B presses the Hold button, Phone B's user hold source is

  streamed to Phone A.

  Network hold: A network hold occurs when a call is placed on hold as part of the processing of a supplementary service, such as park, transfer, or conference. If Phone B presses the Transfer button to transfer a call, Phone A still gets placed

  on hold but hears Phone B's network audio source while the rest of the transfer operations complete.

• Question 152:

  Refer to the exhibit.

  

  Users report that when they dial to Cisco Unity Connection from an external network, they cannot enter any digits. Assuming only in-band DTMF is supported, what is a reason for this malfunction?

  A. The negotiated RTP port is outside of the range described by RFC, so inband DTMFs do not work.

  B. There is SIP Delayed Offer. DTMF is supported only in Early Offer.

  C. The rtpmap:0 value for the negotiated codec is marking DTMF as inactive.

  D. No DTMF is negotiated.

  Correct Answer: D

• Question 153:

  A solution for a large company is being reconfigured to optimize for cost saving. The company has an extensive global QoS-enabled network with enough bandwidth to create a converged network. Local calls are relatively inexpensive in

  countries the company have operations, but long distance and international calls are expensive.

  Which type of configuration supported by Cisco UCM would help optimize cost control for this company?

  A. standard local route groups for mobile users

  B. Mobile and Remote Access

  C. high complex codec support like G.729 to minimize bandwidth usage

  D. tail end hop off

  Correct Answer: D

• Question 154:

  

  Refer to the exhibit. A collaboration engineer is troubleshooting an issue where the PSTN calls of a Cisco UCM IP phone user are not reaching the PSTN gateway. Which action resolves the issue?

  A. Change the calling search space of the user's line or device.

  B. Change the “Call Classification” to “OnNet” on the route pattern.

  C. Ensure that the user's phone is assigned to a device pool with the correct local route settings.

  D. Deselect “Block this pattern” on the route pattern.

  Correct Answer: D

• Question 155:

  An engineer is implementing survivability for a collaboration environment. The environment is utilizing a centralized Cisco UCM at the headquarters and Cisco IOS-XE gateways in the remote branches. Which action must the engineer take to enable both shared lines and B-ACD for SIP branch phones during a WAN outage?

  A. Configure mode esrst under voice register global configuration mode.

  B. Configure mode srst under telephony-service configuration mode.

  C. Configure mode esrst under voice service voip configuration mode.

  D. Configure mode esrst under telephony-service configuration mode.

  Correct Answer: B

• Question 156:

  Users report silence on the line when they try to connect to external voice numbers. The company is using Cisco 8865 phones with Cisco UCM connected to a gateway with two T1 circuits. The MGCP server seems to be responding. Which action must the engineer take to begin to investigate the media for this type of issue?

  A. Run RTMP on the Cisco router.

  B. Verify that the MGCP service is running under serviceability in Cisco UCM.

  C. Run the debug mgcp media command on the Cisco router.

  D. Run the debug H.323 gateway command on the Cisco router.

  Correct Answer: C

• Question 157:

  What is a function of the metadata carried in SIP sessions between the recording client and the recording server?

  A. It forks RTP media to the recorder.

  B. It provides advanced capabilities, such as speech analytics.

  C. It sets up a new SIP session

  D. It identifies the participant change due to transfers during the call.

  Correct Answer: D

• Question 158:

  Some users report poor quality when they travel to another continent and make calls. This issue applies only to one continent and not to others, where typically the dialing is fast and quality is clear. Users experience the same result at home when they call the same numbers in that specific continent. It seems like some users do not exist in the correct PSTN gateway when making calls to a specific country. The company is using TEHO to save on the cost of international or long-distance calling.

  They are also using a globalized dial plan. What is the cause of the issue?

  A. CUBE is not configured for TEHO in the specific country.

  B. A local route group is not added to the route pattern.

  C. The users are missing this specific gateway at the device pool level.

  D. Regions in Cisco UCM are not configured correctly.

  Correct Answer: C

• Question 159:

  An administrator is configuring Meet-me conferencing in a Cisco UCM deployment and has created the Meet-me number and ensured that it is in a partition accessible by all devices. Which two additional steps must the administrator perform? (Choose two.)

  A. Ensure that conferencing-initiating devices are using a media resource group list that contains at least one Cisco UCM conference bridge.

  B. Disable Early Media on the SIP profile of all devices that will use Meet-me conferencing.

  C. Enable Meet-me conferencing in enterprise parameters.

  D. Ensure that all devices have G.729 enabled.

  E. Update the softkey template on all phones to ensure that they contain the Meet-me softkey.

  Correct Answer: AE

• Question 160:
