A user is on an outbound call through a Cisco Unified border Element gateway. When the user places the call on hold, the remote party hears silence. The Cisco Unified Communication Manager Cluster is using multicast on hold. The Cisco Unified Border Element Gateway is on the same subnet as the Cisco Unified Communication Manager Cluster.

Which two options will resolve this issue? (Choose two)

  1. Media flow-through must be configured.

  2. CCM-manager music-on-hold should be removed from the configuration.

  3. The session transport UDP command must be configured.

  4. The Cisco unified border Element router must be set up for gateway-based MOH.

  5. The pass-thru content sdp command should be removed.

Answer: A,E Explanation:

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
