Topic 1An administrator is troubleshooting call failures on an H.323 gateway via the CLI. To see signaling for media and call setup,which debug must the Administrator turn on? (Choose two.)

Topic 1What is a description of RTP timestamps or sequence numbers?

An engineer is troubleshooting local ringback on a Cisco SIP gateway The gateway is not ignoring the SIP 180 response with SDP from the service provider, and the far end device is sending the 180 with SDP to play ringback from the IP address specified m the SDP Which configuration change must be made on the gateway to resolve the issue?

Topic 1What is first preference condition matched in a SIP-enabled incoming dial peer?

An engineer has temporarily disabled toll fraud prevention for SIP line calls on a Cisco CME12.6x and must enforce security and toll fraud prevention for the SIP line side on Cisco Unified CME. Which configuration must be used to start this process?

Topic 1Refer to the exhibit. A user reports that when they call a specific phone number, no one answers the call, but when they callfrom a mobile phone, the call is answered. The engineer troubleshooting the issue is expecting the far-end gateway to cutthrough audio on the 183 Session Progress SIP message. Which SIP Profile configuration element is necessary for theCisco Unified Communications Manager to send acknowledgement of provisional responses?

Topic 1Which two extended capabilities must be configured on dial peers for fast start-to-early media scenarios (H.323 to SIPinterworking)? (Choose two.)

Topic 1When an administrator troubleshoots H.323 call setup, which message gives an alert that the called party is being notifiedabout the call?

Topic 1End users at a new site report being unable to hear the remote party when calling or being called by users at headquarters.Calls to and from the PSTN work as expected. To investigate the SIP signaling to troubleshoot the problem, which field canprovide a hint for troubleshooting?

Topic 1Refer to the exhibit. In an active SIP call between phone user A and phone user B, phone A initiates a call transfer to phoneuserC. What are two results from this action? (Choose two.)

Topic 1Refer to the exhibit. While troubleshooting call failures on the Cisco Unified Border Element, an administrator notices thatmessages are being sent to the service provide, but there is no response. The administrator later learns that this SIPprovider does not support PRACK. Which header should be removed from the SIP message to resolve this issue?

Topic 1Why would RTP traffic that is sent from the originating endpoint fail to be received on the far endpoint?

Topic 1An administrator is troubleshooting a one-way audio issue for a call that uses H.323 protocol in slow-start mode. Theadministrator requests that the IP and port information of the Real-Time Transport Protocol traffic that had the one-way audiocall is provided. The H.225 and H.245 messages for one of the one-way audio calls are gathered and the call flow has notinvoked any media resources. Where is the RTP IP and port information for both sides found?

The SIP session refresh timer allows the RTP session to stay active during an active call. The Cisco UCM sends either SIP-INVITE or SIP-UPDATE messages in a regular interval of time throughout the active duration of the call. During a troubleshooting session, the engineer finds that the Cisco UCM is sending SIP-UPDATE as the SIP session refresher, and the engineer would like to use SIP-INVITE as the session refresher. What configuration should be made in the Cisco UCM to achieve this?

Topic 1Refer to the exhibit. Users report that when they dial to Cisco Unity Connection from an external network, they cannot enterany digits. Assuming only in-band DTMF is supported, what is a reason for this malfunction?

Topic 1A support engineer is troubleshooting a voice network. When conducting a search for call setup details related to callingsearch space issues, which trace files should be investigated?

Refer to the exhibit. A Cisco Unified Border Element continues to send 180/183 with the required: 100rel header to Cisco UCM. and the call eventually disconnects How is the issue resolved?

Topic 1Cisco SIP IP telephony is implemented on two floors of your company. Afterward, users report intermittent voice issues incalls established between floors. All calls are established, and sometimes they work well, but sometimes there is one-wayaudio or no audio. It is determined that there is a firewall between the floors, and the administrator reports that it is allowingSIP signaling and UDP ports from 20000 to 22000 bidirectionally. What are two solutions for this issue?(Choose two.)

Topic 1Which section under the Real-Time Monitoring Tool allows for reviewing the call flow and signaling for a SIP call in real time?

In an active SIP call between phone user A and phone user B, phone A initiates a call transfer to phone user
