Demo Questions

Where is the dtmf-relay command configured on Cisco Unified Border Element?

in the voice-class VoIP configuration
in the VoIP dial peer
in global SIP configuration
in the VoIP or POTS dial peers

Correct answer: B

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?

Change the destination-pattern on the outgoing dial peer to match ''444333222''.
Set up translation-profile on the incoming dial peer to match incoming traffic.
Create specific matching for ''222333444'' on the incoming dial peer.
Fix the voice translation-rule to match specifically number ''222333444'' and change it to ''444333222''.

Correct answer: B

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?

rule 1 /^/+$[^1].*$/ /011\1/
rule 1/^\+1$[2-9]..[2-9]......$$/ /\1/
rule 1 /^$[2-9]..[2-9]......$$/ /\1/
rule 1 /^\+1$[2-9]..[2-9]......$$/ /\0/

Correct answer: B

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.)

Enable PRACK.
Enable Early Offer on the Cisco Unified Border Element.
Enable the supplementary-service media-renegotiate command.
Enable Media Flow Around
Enable Mid-Call Signaling Consumption.

Correct answer: AB

Which IOS command creates a SIP-enabled dial peer?

voice dial-peer 20 sip
dial-peer voice 20 voip
dial-peer voice 20 pots
dial peer voice 20 sip

Correct answer: B

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?

missing Call Admission Control
codec mismatch
ptime mismatch
phone class of service issue

Correct answer: A

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.)

[email protected]
*@example.com
gateway.corporate.local
example.com
*.*

Correct answer: BE

Which two statements are correct with respect to the Client Matter Code setting in the route pattern configuration? (Choose two.)

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.
If you check the Allow Overlap Sending check box, the Require Client Matter Code check box becomes disabled.
If you check the Allow Overlap Sending check box, you can also check the Require Client Matter Code check box.
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.
The Client Matter Code has the option to configure Authorization Level such as in the Forced Authorization Code.

Correct answer: AB

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?

Router(conf-voi-serv)# dlisable-early-media 180
Router(conftg-sip-ua)# disable-early-media 180
Router(con(-voi-serv)# no disable-early-media 180
Router(config-sip-ua)# no disable-early-media 180

Correct answer: B

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?
