WAN network, but the user experiences choppy or clipped audio. What is the
cause of this issue?

A.

missing Call Admission Control

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

A.

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

B.

Cisco Unified Communications Manager invoked media termination point resources.

C.

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

D.

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

A.

WAN connectivity

B.

LAN connectivity

C.

route pattern

D.

route list and route group

C.

Set the correct subnet under Device Mobility Info.

D.

Set Device CSS under Current Device Mobility Settings.

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

B.

interworking between h245-signal and rtp-nte

C.

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

D.

Refer to the exhibit.

In an active SIP call between phone user A and phone user B, phone A initiates a call transfer to phone user C. Which two scenarios are correct? (Choose two.)

A.

Phone_A sends a SIP-REFER message to the Cisco Unified Communications Manager
with Phone_C information in the Refer-To section.

B.

information in the Refer-To section.

C.

As soon as Phone_A presses the Transfer button for the first time, Phone_B hears the
MOH and the MOH audio is chosen from Phone_B User Hold MOH Audio Source settings.

D.

As soon as Phone_A presses the Transfer button for the first time, Phone_B hears the
music on hold and the MOH audio is chosen from Phone_A Network Hold MOH Audio
Source settings.
