Refer to the exhibit.

A CUBE Cluster is working in HSRP box-to-box failover model. When the phone A calls Cisco WebEx meeting server to start a conference session, no DTMF tones are recognized. Which configuration change will fix this problem when configured on both CUBEs?

A. Voice-class sip asymmetric payload dtmf in dial-peer configuration

B. Dtmf-relay rtp-nte digitdrop in the dial-peer configuration

C. Media flow-around under voice service voip configuration

D. Modem relay nse payload-type101 underglobal sip configuration

E. Asymmetric payload full configured under global sip configuration

Answer: E


Symmetric and Asymmetric Calls

Cisco UBE supports dynamic payload type negotiation and interworking for all symmetric and asymmetric payload type combinations. A call leg on Cisco UBE is considered as symmetric or asymmetric based on the payload type value exchanged during the offer and answer with the endpoint:

u2022 A symmetric endpoint accepts and sends the same payload type.

u2022 An asymmetric endpoint can accept and send different payload types.

The Dynamic Payload Type lnterworking for DTMF and Codec Packets for SlP-to-SlP Calls feature is enabled by default for a symmetric call. An offer is sent with a payload type based on the dial-peer configuration. The answer is sent with the same payload type as was received in the incoming offer. When the payload type values negotiated during the signaling are different, the Cisco UBE changes the Real-Time Transport Protocol (RTP) payload value in the VolP to RTP media path.

To support asymmetric call legs, you must enable The Dynamic Payload Type lnterworking for DTMF and Codec Packets for SlP-to-SlP Calls feature. The dynamic payload type value is passed across the call legs, and the RTP payload type interworking is not required. The RTP payload type handling is dependent on the endpoint receiving them.

Configuring global SlP asymmetric payload support.


Router(conf-serv-sip)# asymmetric payload full

The dtmf and dynamic-codecs keywords are internally mapped to the full keyword to provide asymmetric payload type support for audio and video codecs, DTMF, and NSEs.
