A collaboration engineer using the Show eigrp service-family External-client IOS command, noticed that a CUCM failed to register as an external SAF Client on Cisco IOS router named Site CRTR. The engineer has collected snippets of the IOS configuration screenshots and CUCM trace shown in the exhibit.

What is the reason for the registration failure?

  1. Password mismatch between CUCM and Router SAF configuration

  2. Sf-interface loopback0 command missing under service-family ipv4 autonomous-system 1

  3. SIP trunk IP address pointing to a different address than SAF Forwarder address

  4. Name mismatch between SAF Forwarder name info field and external-client name on router

  5. IP multicast-routing command missing on router configuration

Answer: B

Question No: 115 – (Topic 1)

(Choose two.)

  1. 80.4 kb/s

  2. 91.2 kb/s

  3. 69.6 kb/s

  4. 78.4 kb/s

  5. 6 kb/s 2.4

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?

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

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

  3. Media flow-around under voice service voip configuration

  4. Modem relay nse payload-type101 underglobal sip configuration

  5. Asymmetric payload full configured under global sip configuration

Answer: E Explanation:

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:

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

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

    The Dynamic Payload Type Interworking for DTMF and Codec Packets for SIP-to-SIP 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 VoIP to RTP media path.

    To support asymmetric call legs, you must enable The Dynamic Payload Type Interworking for DTMF and Codec Packets for SIP-to-SIP 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 SIP 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.

After importing the certificates into each of the clusters, the administrator tested Cisco EMCC on a phone, but received “Login is unavailable (208)”.

    Which two steps resolve this error? (Choose two)

    1. Update the cluster IDs so that they are unique in the EMCC network.

    2. Enable the Allow Proxy service parameter on both clusters.

    3. Restart the Cisco CallManager and Cisco Tomcat Servers.

    4. Associate a user device profile for the user in the remote cluster.

    5. Consolidate the exported certificates and reimport into each cluster.
