An administrator is implementing a new dial-plan on Cisco Unified Border Element. The administrator must ensure that incoming dial-peers are matched based on the IP address from where the incoming request originates.
Which dial-peer configuration should be applied to accomplish this requirement?
- A . dial-peer voice 1 voip incoming url via
- B . dial-peer voice 1 voip incoming url request
- C . dial-peer voice 1 voip incoming called-number
- D . dial-peer voice 1 voip incoming url to
Refer to the exhibit.
Refer to the exhibit An engineer deploys a Cisco Unified Border Element for SIP trunk interconnection to an ITSP The engineer performs test calls but there is no audio when the called party picks up the phone.
What must the engineer do to resolve the issue?
- A . Disable SIP User Agent bind status (media).
- B . Decrease the SIP max-forwards value to 16.
- C . Disable SIP early-media for 180 responses with SDP
- D . Enable Check media source packets.
Refer to the exhibit.
A company deploys an additional instance of Cisco UCME named CUCME 2 in a branch office. Phones in the main office are register of Unified CME named CUCME 1. Phones in the branch office are registered with their extension to CUCME 2. The engineer needs to configure CUCME the branch office using an 8-kbps codec.
Which configuration should be applied to CUCME 1?

B)
C)
D)

- B . Option B
- C . Option C
- D . Option D

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”.
Users are reporting that several inter-site calls are failing, and the message "not enough bandwidth" is showing on the display. Voice traffic between locations goes through corporate WAN. and Call Admission Control is enabled to limit the number of calls between sites.
How is the issue solved without increasing bandwidth utilization on the WAN links?
- A . Disable Call Admission Control and let the calls use the amount of bandwidth they require.
- B . Configure Call Queuing so that the user waits until there is bandwidth available
- C . Configure AAR to reroute calls that are denied by Call Admission Control through the PSTN.
- D . Reroute all calls through the PSTN and avoid using WAN.
A company has an SRST gateway running an IOS XE image. The company plans to enable the IPv6 addressing companywide.
To enable the IPv6 in a unified SRST gateway to support SIP phones, what are two supported supplementary features for an IPv6 fallback scenario? (Choose two.)
- A . three-way conference
- B . secure SIP lines
- C . T.38 fax relay
- D . transcoding
- E . SIP trunk

DRAG DROP
A customer wants to configure their team of 10 agents to answer incoming calls to a common central number. The phone for each team member must ring in sequence and ring four times before moving to the next member’s phone.
Drag and drop the steps from the left into the order on the right to make this happen.
