The secondary gateway is for any calls that start with 9713, but this is not yet configured. The admin does not want to add more route patterns other than the current 9 prefix for the gateway to the Cisco UCM. How must the Cisco UCM be configured to meet the requirements?
Configure two CSSs. then add a translation pattern with the secondary CSS to send calls with 9713 to the secondary gateway.
Configure two partitions and two CSSs, then add a translation pattern with the secondary CSS to send all calls with 9713 to the secondary gateway.
Create a Standard Route Group to dynamically route calls with prefix 9713 to the secondary gateway.
Configure a Route Group and a Route List to send calls with prefix 9713 to the secondary gateway.

A customer reports audio quality issues between video endpoints in the HQ location in California and one of the branches in Texas. Which two actions must RTCP take to troubleshoot this issue? (Choose two.)
Compress the headers of RTP traffic to lower the bandwidth consumption over the WAN. which allows more calls with less bandwidth consumed.
Configure the rtcp keepalive command in Cisco Unified Border Element to generate reports, which can be reviewed using the debug voip rtcp packet command.
Allow for VAD to be used for calls using the G7.29 codec, which reduces the usage of the WAN bandwidth and saves around 30% of bandwidth per call.
Encrypt the media to stop rogue devices from replying and putting that traffic back on the WAN, which avoids any extra bandwidth and ensures the quality of the calls.
Gather statistics on a media connection and information such as packets sent, lost packets, jitter, feedback, and round-trip delay. This information can help isolate the type of audio quality issues and the direction of the affected traffic.
A collaboration engineer is configuring call pickup for a Cisco UCM user that currently has a working BLF speed dial button for the teammate's extension. The user wants to see calls ringing on the teammate's extension and to answer those calls by pressing the BLF speed dial button. Which configuration step meets this requirement?
Set the call pickup group to <none> for both extensions.
Select the call pickup checkbox on the BLF speed dial settings.
Assign both extensions to the same partition.
Assign the extensions to different call pickup groups.
A customer reports that outbound calls from Cisco UCM to Cisco Unified Border Element are not getting early media. During troubleshooting, the customer finds that Cisco UCM is sending a delayed offer SIP INVITE. Cisco Unified Border Element responds with a 183 Session Progress with SDP message. However, the customer finds that Cisco UCM does not respond to the 183 messages. Which action must the customer perform to resolve the problem?
On Cisco Unified Border Element, configure midcall-signaling passthru.
On Cisco UCM, change the 'Early Offer support for voice and video calls' field on the SIP profile that is applied to the SIP trunk to Disabled.
On Cisco Unified Border Element, configure early-offer forced.
On Cisco UCM. change the 'SIP ReHXX Options' field on the SIP profile that is applied to the SIP trunk to Send PRACK if 1xx Contains SDP.

Configure Hunt Pilot Queuing.
Service the Cisco IP Voice Media Streaming (IPVMS) application.
Configure Music On Hold.
Configure announcements.
