Multicast Music-on-Hold Support on Cisco UBE

Last Updated: August 03, 2011

First Published: July 22, 2011

Last Updated: July 22, 2011

The Multicast Music-on-Hold (MMOH) feature enables you to subscribe to a music streaming service when you are using a Cisco Unified Border Element. Music streams from an MMOH server to the interface of Cisco UBE, which then converts it into unicast. To play the MMOH to customers using Cisco UBE, you must enable the MMOH feature on Cisco UBE.

Restrictions for Multicast Music-on-Hold Support on Cisco UBE

  • The Multicast Music-on-Hold (MMOH) feature will not work when the Session Description Protocol (SDP) Passthrough feature is enabled on Cisco UBE.
  • The MMOH feature will work for Low Density Transcoded calls but not for High Density Transcoded calls.
  • MMOH is supported only on SIP-to-SIP call flows on Cisco UBE.

Information About Multicast Music-on-Hold Support onCisco UBE

Multicast Music-on-Hold

To play Multicast Music-on-Hold (MMOH) to customers using Cisco UBE, you must enable the MMOH feature on Cisco UBE. When Cisco UBE receives an MMOH call, it converts the multicast address received on the inbound leg into a unicast address and sends the address on the outbound leg.

Cisco UBE uses preconfigured CLIs to "listen" for Real-Time Transport Protocol (RTP) packets that are broadcast from an MMOH server in the network and converts them to unicast. When a call is placed on hold, the MOH server streams the RTP packets to the Cisco UBE interface. This interface converts the RTP packets to unicast and relays the packets to the appropriate voice interfaces that have been placed on hold.


Note
MMOH is already supported on SIP-TDM gateways.

Verifying the MMOH Support on Cisco UBE

Perform this task to verify the MMOH support on Cisco UBE. The show commands can be entered in any order.

SUMMARY STEPS

1.    enable

2.    show ccm-manager music-on-hold

3.    show voip rtp connections

4.    show call active voice compact


DETAILED STEPS
Step 1   enable

Enables privileged EXEC mode.



Example:

Router> enable

Step 2   show ccm-manager music-on-hold

Displays information about all the multicast music-on-hold (MOH) sessions in the gateway at any given time.



Example:

Router# show ccm-manager music-on-hold Current active multicast sessions: 1 Multicast Address RTP port number Packets in/out CallId Codec Incoming Interface 239.1.1.1 16386 614/614 132 g711ulaw Gi0/0

Step 3   show voip rtp connections

Displays RTP-named event packets.



Example:

Router# show voip rtp connections VoIP RTP active connections: No. CallId dstCallId LocalRTP RmtRTP LocalIP RemoteIP 1 140 141 18792 18638 9.42.30.10 9.42.30.32 2 141 140 19256 26184 9.42.30.10 9.42.30.189 Found 2 active RTP sessions

Step 4   show call active voice compact

Displays a compact version of voice calls in progress.



Example:

Router# show call active voice compact <callID> A/O FAX T<sec> Codec type Peer Address IP R<ip>:<udp> Total call-legs: 3 140 ANS T644 g711ulaw VOIP P10000 9.42.30.32:18638 141 ORG T644 g711ulaw VOIP P708090 9.42.30.189:26184

145 ORG T643 g711ulaw VOIP P595959 9.42.29.7:3852

Troubleshooting Tips

The following commands can help troubleshoot MMOH:

  • debug ccm-manager music-on-hold [ all | errors | events ]
  • debug voip rtp
  • debug ccsip all
