When a Cisco Unified Border Element connects two VoIP streams using flow-around media, which
of the following options describe the components of the call that flow around and the components
that flow through the device?

A.
All security information flows through the Cisco Unified Border Element, and all call signaling
and RTP flows around the device.

B.
Call signaling flows through and call media flows around the device.

C.
Call media flows through and call signaling flows around the device.

D.
The initial call-signaling traffic flows through the device to initiate the call and then all
subsequent calls flow around the device.

Explanation:
Configuring Media Flow-AroundThis feature adds media flow-around capability on
the Cisco Unified Border Element by supporting the processing of call setup and teardown
requests (VoIP call signaling) and for media streams (flow-through and flow-around). Media flow

around can be configured the global level or it must be configured on both incoming and outgoing
dial peers. If configured only on either the incoming or outgoing dialpeer, the call will become a
flow-through call.Media flow-around is a good choice to improve scalability and performance when
network-topology hiding and bearer-level interworking features are not requiredWith the default
configuration, the Cisco UBE receives media packets from the inbound call leg, terminates them,
and then reoriginates the media stream on an outbound call leg. Media flow-around enables media
packets to be passed directly between the endpoints, without the intervention of the Cisco UBE.
The Cisco UBE continues to handle routing and billing functions.To specify media flow-around for
voice class, all VoIP calls, or individual dial peers, perform the steps in this
section.References:http://www.cisco.com/en/US/prod/collateral/voicesw/ps6790/gatecont/ps5640/
