• Question 105:

  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.

  Correct Answer: AB

• Question 106:

  Refer to the exhibit.

  

  Users report that outbound PSTN calls from phones registered to Cisco UCM are not completing. The local service provider in North America has a requirement to receive calls in 10-digit format. The Cisco UCM 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 rule modifies DNIS in the format that the provider is expecting?

  A. rule 1 /^\+\([^1].*\)/ /011\1/

  B. rule 1/^\+1\([2-9]..[2-9]......$\)/ /\1/

  C. rule 1 /^\([2-9]..[2-9]......$\)/ /\1/

  D. rule 1 /^\+1\([2-9]..[2-9]......$\)/ /\0/

  Correct Answer: B

• Question 107:

  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 UCM is expecting the called number to be delivered as "444333222". The administrator already verified that the IP address of the Cisco UCM is set up correctly, and there are no dial peers configured other than those shown in the exhibit. Which action should 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".

  Correct Answer: B

• Question 108:

  An administrator is working on an issue between the customer's Cisco Unified Border Element and the service provider. The provider only wants to see mid-call signaling from the Cisco Unified Border Element for fax calls. Which command must be configured on Cisco Unified Border Element?

  A. midcall-signaling passthru

  B. no update-callerid

  C. midcall-signaling passthru media-change

  D. midcall-signaling preserve-codec

  Correct Answer: C

• Question 109:

  For a SIP to SIP call flow, when does Cisco Unified Border Element require transcoding resources for DTMF?

  A. interworking between an OOB method and RFC2833 for flow-around calls

  B. interworking between H.245-signal and rtp-nte

  C. interworking between an OOB method and RFC2833 for flow-through calls

  D. interworking between H.245-alpha numeric and sip-kpml

  Correct Answer: A
