239.1.1.5
Enables multicast of MOH from a branch office
flash MOH file to IP phones in the branch office.
•
multicast-address
and
port
port
—Declares
the IP address and port number of MOH
packets that are to be multicast. The multicast
IP address and port must match the IP address
and the port number that Cisco Unified CM is
configured to use for multicast MOH. If you
are using different codecs for MOH, these
might not be the base IP address and port,
instead an incremented IP address or port
number. See the
“Configuring the MOH
Audio Source to Enable Multicasting” section
on page 289
. If you have multiple audio
sources configured on Cisco Unified CM,
ensure that you are using the audio sources’s
correct IP address and port number.
•
route
—(Optional) List of explicit router
interfaces for the IP multicast packets.
•
ip-address-list
—(Optional) List of up to four
explicit routes for multicast MOH. The
default is that the MOH multicast stream is
automatically output on the interfaces that
correspond to the address that was configured
with the ip source-address command.
Step 15
exit
Example:
Router(config-cm-fallback)# exit
Exits call-manager-fallback configuration mode.
