DETAILED STEPS
Command or Action
Purpose
Step 1
call-manager-fallback
Example:
Router(config)# call-manager-fallback
Enters call-manager-fallback configuration mode.
Step 2
max-dn
max-directory-number
Example:
Router(config-cm-fallback)# max-dn 1
Sets the maximum possible number of virtual voice ports
that can be supported by a router.
•
max-directory-number
—Maximum number of
directory numbers or virtual voice ports supported by
the router. The maximum possible number is
platform-dependent. The default is 0.
Step 3
multicast moh
multicast-address

[
route
ip-address-list
]
Example:
Router(config-cm-fallback)# multicast moh
239.1.1.1 port 16386 route 239.1.1.2 239.1.1.3
239.1.1.4 239.1.1.5
Enables multicast of MOH from a branch office flash MOH
file to IP phones in the branch office.
Note
This command must be used to source live feed
MOH to multicast Cisco Unified CM mode. It is not
required in strict SRST mode.
•
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 Communications Manager 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, but 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’ correct IP address
and port number.
•
route
ip-address-list
—(Optional) Declares the IP
address or addresses from which the flash MOH
packets can be transmitted. A maximum of four IP
address entries are allowed. If a
route
keyword is not
configured, the Cisco Unified SRST system uses the
ip source-address
command value configured for
Cisco Unified SRST.
