Correct Answer: A,E
Configuring the media flow-around command is required for Session Description Protocol (SDP) pass-through. When flow-around is not configured, the flow-through mode of SDP pass-through will be functional. *When the dial-peer media flow mode is asymmetrically configured, the default behavior is to fallback to SDP pass-through with flow-through. SDP pass-through is addressed in two modes: *Flow-through--Cisco UBE plays no role in the media negotiation, it blindly terminates and re- originates the RTP packets irrespective of the content type negotiated by both the ends. This supports address hiding and NAT traversal. *Flow-around--Cisco UBE neither plays a part in media negotiation, nor does it terminate and re- originate media. Media negotiation and media exchange is completely end-to-end. When SDP pass-through is enabled, some of interworking that the Cisco Unified Border Element currently performs cannot be activated. These features include: *Delayed Offer to Early Offer Interworking *Supplementary Services with triggered Invites *DTMF Interworking scenarios *Fax Interworking/QoS Negotiation *Transcoding
