Refer to the exhibit.
Calls incoming from the provider are not working through newly set up Cisco Unified Border Element. Provider engineers get the 404 Not Found SIP message. Incoming calls are coming from the provider with called number “222333444” and Cisco Unified Communications Manager is expecting the called number to be delivered as “444333222”. The administrator already verified that the IP address of the Cisco Unified CM is set up correctly and there are no dial peers configured other than those shown in the exhibit.
Which action must the administrator take to fix the issue?
- A . Change the destination-pattern on the outgoing dial peer to match “444333222”.
- B . Set up translation-profile on the incoming dial peer to match incoming traffic.
- C . Create specific matching for “222333444” on the incoming dial peer.
- D . Fix the voice translation-rule to match specifically number “222333444” and change it to “444333222”.
Refer to the exhibit.
Users report that outbound PSTN calls from phones registered to Cisco Unified Communications Manager are not completing. The local service provider in North America has a requirement to receive calls in 10-digit format. The Cisco Unified CM sends the calls to the Cisco Unified Border Element router in a globalized E.164 format. There is an outbound dial peer on Cisco Unified Border Element configured to send the calls to the provider. The dial peer has a voice translation profile applied in the correct direction but an incorrect voice translation rule applied, which is shown in the exhibit.
Which rule modified DNIS in the format that the provider is expecting?
- A . rule 1 /^/+([^1].*)//0111/
- B . rule 1/^+1([2-9]..[2-9]……$)//1/
- C . rule 1 /^([2-9]..[2-9]……$)//1/
- D . rule 1 /^+1([2-9]..[2-9]……$)// /
Refer to the exhibit.
An administrator is troubleshooting why users are not hearing audio when dialing long distance numbers across their Cisco Unified Border Element. The customer’s carrier has a requirement that dialing long distance requires an access code to be entered.
Looking at the exhibit, what two actions can be taken to correct signaling? (Choose two.)
- A . Enable PRACK.
- B . Enable Early Offer on the Cisco Unified Border Element.
- C . Enable the supplementary-service media-renegotiate command.
- D . Enable Media Flow Around
- E . Enable Mid-Call Signaling Consumption.
Which IOS command creates a SIP-enabled dial peer?
- A . voice dial-peer 20 sip
- B . dial-peer voice 20 voip
- C . dial-peer voice 20 pots
- D . dial peer voice 20 sip
A user in location X dials an extension at location Y. The call travels through a QoS-enabled WAN network, but the user experiences choppy or clipped audio.
What is the cause of this issue?
- A . missing Call Admission Control
- B . codec mismatch
- C . ptime mismatch
- D . phone class of service issue
An engineer must route all SIP calls in the form of <user>@example.com to the SIP trunk gateway corporate local.
Which two SIP route patterns can be used to accomplish this task? (Choose two.)
- A . [email protected]
- B . *@example.com
- C . gateway.corporate.local
- D . example.com
- E . *.*
Which two statements are correct with respect to the Client Matter Code setting in the route pattern configuration? (Choose two.)
- A . The Client Matter Code feature does not support overlap sending because the Cisco Unified CM cannot determine when to prompt the user for the code.
- B . If you check the Allow Overlap Sending check box, the Require Client Matter Code check box becomes disabled.
- C . If you check the Allow Overlap Sending check box, you can also check the Require Client Matter Code check box.
- D . The Client Matter Code feature does support overlap sending because the Cisco Unified Communications Manager can determine when to prompt the user for the code.
- E . The Client Matter Code has the option to configure Authorization Level such as in the Forced Authorization Code.
A network engineer designs a new dial plan and wants to block a certain range of numbers (8135100 through 8135105).
What is the most specific route pattern that can be configured to block only the numbers in this range?
- A . 813510[012345]
- B . 813510[12345]
- C . 813510[^0-5]
- D . 81XXXXX
Which two descriptions of the Standard Local Route Group deployment are true? (Choose two.)
- A . can be associated under the route group
- B . can be associated only under the route list
- C . chooses the route group that is configured under the device pool of the calling-party device
- D . chooses the route group that is configured under the device pool of the called-party device
- E . can be assigned directly to the route pattern
Refer to the exhibit.
An engineer configures Cisco Unified Border Element to connect the enterprise VoIP network with a SIP telephony provider. Calls are not working in either direction.
What must be configured in the dial peer 1 to fix the issue?
- A . answer-address 555 ……..
- B . codec g729
- C . session-protocol sipv2
- D . incoming called number 555…….
