Question 70

Refer to the exhibit. An engineer is troubleshooting an issue where inbound calls are failing after they are transferred. The provider reports that UPDATE is not supported, and this is causing the calls to fail. Which command should resolve this issue?

A) no midcall-signaling passthru
B) no update-callerid
C) no contact-passing
D) rel1xx require "100rel"

Question 71

Refer to the exhibit. Regions have been configured for all major branches based on the available circuit bandwidth. Some calls from Region A endpoints to Region B endpoints are failing to connect. How is the issue resolved?

A) Update the calling search space for affected endpoints to none.
B) Update all regions to 8 kbps maximum audio bitrate.
C) Increase the number of available media termination points.
D) Add a media resource to transcode between available capabilities.

Question 72

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

A) Require: 100rel
B) Content-Type: application/sdp
C) Contact:
D) Content-Disposition: session;handling=required

Question 73

Refer to the exhibit. An administrator is troubleshooting a problem in which some outbound calls from an internal network to the Internet telephony service provider are not getting connected, but some others connect successfully. The firewall team found that some call attempts on port 5060 came from an unrecognized IP that has not been defined in the firewall rule. What should the administrator configure in the Cisco Unified Border Element to fix this issue?

A) use of port 5061 for SIP secure
B) access list allowing the firewall IP
C) bind signaling and media to the loopback interface
D) ip prefix-list to filter the unwanted IP address

Question 74

In Cisco UCM, which tool is used to check SIP traces?

A) MTP
B) CCSIP
C) RTMT
D) OS Administration Page

Question 75

A customer routes PSTN calls to ITSP through a SIP trunk on Cisco UCM that forwards and receives calls to and from ITSP. ITSP is set to send an E.164 number when the customer's extension is four digits. Which action should be taken to route the incoming calls to four-digit extensions?

A) Configure a voice translation profile to map the E.164 number to four digits and assign it to the incoming dial-peer on Cisco Unified Border Element.
B) Set the Significant Digits to 8 on the SIP trunk
C) Set the Significant Digits to 4 on the SIP trunk
D) Configure a voice translation rule to map the E164 number to four digits and assign it to the incoming dial-peer on Cisco Unified Border Element.

Question 76

Refer to the exhibit. Outbound calls to the service provider cause intermittent errors due to a codec mismatch. The internal network sends early offer SDP that contains only G.711 A-law. The service provider reports that some destinations support only G.711 A-law while others support only iLBC. The service provider also allows only 20 active calls at a time. Which configuration allows successful media negotiation for all calls using outbound dial peers 5002 and 5003?

A) dial-peer voice 5002 voip codec g711alaw ilbc ! dial-peer voice 5003 voip
B) voice-class codec 101 offer-all
C) voice-class codec 101
D) codec g711alaw codec ilbc

Question 77

An engineer must configure a secure SIP trunk with a remote provider, with a specific requirement to use port 5065 for inbound and outbound traffic. Which two items must be configured to complete this configuration? (Choose two.)

A) Incoming Port in SIP Information section of the SIP Trunk configuration.
B) Incoming Port in Security Information of the SIP Profile configuration.
C) Destination Port in SIP Information section of the SIP Trunk configuration
D) Incoming Port in SIP Trunk Security Profile configuration
E) Destination Port in SIP Trunk Security Profile configuration

Question 78

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?

A) Change Session Refresh Method on the SIP profile to INVITE. Change Session Refresh Method on the SIP profile to INVITE.
B) Increase Retry INVITE to 20 seconds on the SIP profile. Increase Retry INVITE to 20 seconds on the SIP profile.
C) Enable Send send-receive SDP in mid-call INVITE on the SIP profile. Enable Send send-receive SDP in mid-call INVITE on the SIP profile.
D) Enable SIP Rel1XX Options on the SIP profile. SIP Rel1XX Options

Question 79

Refer to the exhibit. An engineer is troubleshooting an issue where inbound calls to Cisco UCM with early media fail to establish. While investigating the issue, the engineer finds that Cisco UCM is set to require a PRACK, but the Cisco Unified Border Element is not sending it. Which command is causing this issue?

A) voice-class midcall-signaling block
B) voice-class sip rel1xx disable
C) voice-class sip early-media update block
D) voice-class sip conn-reuse

Question 80

Where on Cisco UCM does the administrator configure the standard local route group for a group of devices?

A) System > Location Info
B) Call Routing > Route/Hunt > Local Route Group Names
C) System > Device Pool
D) Call Routing > Emergency Location > Emergency Location (ELIN) Groups
