Voice Gateways And Session Border Controllers

You need to enforce a specific codec for calls traversing a CUBE. Where is the most appropriate place to apply this configuration?

When troubleshooting CUBE SIP normalization, which tool allows you to view the normalized SIP messages in real-time?

An engineer needs to verify the current active calls on a Cisco IOS XE voice gateway and see details such as call legs, codecs, and durations. Which command should be used?

You are configuring a Cisco IOS XE voice gateway to route inbound SIP calls to different dial peers based on the Request-URI domain. You want to match calls destined to 'example.com' to a specific dial peer. Which configuration element should you use to achieve this?

Which TWO of the following are valid components of a Cisco IOS voice gateway configuration?

You are deploying CUBE. Which command enables the CUBE functionality on the Cisco IOS XE router?

When configuring CUBE, why would you use a 'voice class uri' command?

What is the primary function of a dial-peer destination-pattern?

A Cisco IOS XE gateway is configured with two POTS dial peers that both match an inbound PSTN call on voice port 0/0/0. The first dial peer has preference 1 and destination pattern 9T; the second has preference 2 and destination pattern 9.... An engineer notices that calls are always routed using the second dial peer. What is the most likely explanation?

A Cisco CUBE is deployed to connect a Cisco Unified Communications Manager (CUCM) cluster to a service provider SIP trunk. The service provider requires that all outgoing SIP INVITE messages contain a specific custom header, X-Provider-ID, with a value of 'CUBE123'. Which CUBE configuration is required to insert this header into outgoing INVITEs?

Which TWO of the following are true regarding the use of voice translation-rules?

Which command is used to configure the IP address or hostname of the destination device on a dial-peer?

What is the result of applying 'voice translation-profile' to an incoming dial-peer?

A Cisco IOS XE gateway is failing to route calls because the dial-peer is not matching the incoming call. Which command helps you identify the dial-peer that matched the incoming call?

A CUBE is configured to route calls between Cisco Unified Communications Manager and a SIP provider. The provider sends calls with a '+1' prefix, but the internal dial plan expects calls without the '+'. Which CUBE feature should be used to strip the '+' from the incoming called number before extending the call to Unified CM?

A CUBE is receiving calls but rejecting them due to '488 Not Acceptable Here'. What is the most likely reason?

A Cisco Unified Border Element (CUBE) is deployed between Cisco Unified Communications Manager (CUCM) and a SIP service provider. The provider sends an INVITE with a Diversion header containing a redirecting number. The CUBE must pass the redirecting number to CUCM in the History-Info header instead of the Diversion header. Which SIP profile configuration on CUBE accomplishes this?

A Cisco IOS XE gateway is configured with a POTS dial-peer that forwards calls to a PRI interface. Users report that inbound PSTN calls are being rejected with a cause code indicating that all circuits are busy, even though the PRI shows no active calls. Which command should you use to verify that the POTS dial-peer is matching the inbound calls correctly?

You are configuring a Cisco IOS XE voice gateway to register with an ITSP over SIP. The provider requires registration to be refreshed every 60 seconds. You have already configured the registrar and credentials under sip-ua. Which command correctly sets the registration expiry timer to 60 seconds?

A Cisco Unified Border Element is deployed between Cisco Unified Communications Manager and a SIP provider. The provider requires that the gateway insert a Diversion header containing the original called number when a call is forwarded. The engineer plans to use a SIP profile to accomplish this. Which statement accurately describes the capability of SIP profiles in this scenario?

Which THREE actions are possible using SIP profiles on a CUBE?

A Cisco Unified Border Element (CUBE) is deployed between Cisco Unified Communications Manager and a SIP provider. The provider sends an INVITE with a Diversion header containing the original called number. You need to strip the Diversion header before sending the INVITE to Unified CM. Which configuration element should you use?

A Cisco IOS XE voice gateway is configured with two POTS dial peers pointing to the same FXO port. Dial peer 10 matches destination pattern 911, and dial peer 20 matches destination pattern 9T. An inbound PSTN call arrives and is matched to a VoIP dial peer that forwards it to the gateway's FXO trunk. Which dial peer will the gateway use for the outbound POTS leg, and why?

A Cisco IOS XE voice gateway routes inbound PSTN calls to Cisco Unified Communications Manager. The gateway is configured with dial-peer voice 100 pots, which has no incoming called-number command, and dial-peer voice 200 voip, which points to the CUCM subscriber. An engineer needs the gateway to terminate incoming POTS calls on the POTS dial peer and match outbound calls to the VoIP dial peer based on the called number. Which command must be added to dial-peer voice 100 pots to ensure inbound calls are matched correctly?

A CUBE is configured for H.450.3 call forwarding, but it is not working. What is the most likely cause?

Which TWO of the following are functions performed by the CUBE as a Session Border Controller?

When configuring CUBE for media flow-around, which command ensures the media goes directly between endpoints?

Which component in CUBE is responsible for ensuring that the call session is terminated correctly?
