Question 12

Why would RTP traffic that is sent from the originating endpoint fail to be received on the far endpoint?

Options:

The far end connection data (c=) in the SDP was overwritten by deep packet inspection in the call signaling path.

Cisco Unified Communications Manager invoked media termination point resources.

The RTP traffic is arriving beyond the jitter buffer on the receiving end.

A firewall in the media path is blocking TCP ports 16384-32768.

Question 13

Refer to the exhibit.

An engineer is troubleshooting a call-establishment problem between Cisco Unified Border Element and Cisco UCM. Which command set corrects the issue?

Options:

SIP binding in SIP configuration mode:

voice service voip sip

bind control source-interface GigabitEthernetO/0/0 bind media source-interface GigabitEthernetO/0/0

SIP binding In SIP configuration mode:

voice service volp

sip

bind control source-Interface GlgabltEthernetO/0/1 bind media source-Interface GlgabltEthernetO/0/1

SIP binding In dial-peer configuration mode:

dial-peer voice 300 voip

voice-class sip bind control source-interface GigabitEthernetO/0/1 voice-class sip bind media source-interface GigabitEthernetO/0/1

SIP binding in dial-peer configuration mode:

dial-peer voice 100 volp

voice-class sip bind control source-interface GigabitEthernetO/0/0

voice-class sip bind media source-interface GigabitEthernetO/0/0

Question 14

The SIP session refresh timer allows the RTP session to stay active during an active call. The Cisco UCM sends either SIP-INVITE or SIP-UPDATE messages in a regular interval of time throughout the active duration of the call. During a troubleshooting session, the engineer finds that the Cisco UCM is sending SIP-UPDATE as the SIP session refresher, and the engineer would like to use SIP-INVITE as the session refresher. What configuration should be made in the Cisco UCM to achieve this?

Options:

Enable SIP ReMXX Options on the SIP profile.

Enable Send send-receive SDP in mid-call INVITE on the SIP profile.

Change Session Refresh Method on the SIP profile to INVITE.

Increase Retry INVITE to 20 seconds on the SIP profile.

Question 15

An engineer must implement call restriction to toll-free numbers using a class of restriction in a branch Cisco UCME. In which two places is the corlist incoming or cor Incoming command configured? (Choose two.)
