by a router to 10 and activates the dual-line mode for all IP phones in Cisco Unified CM fallback mode:
call-manager-fallback
max-dn 10 dual-line
exit
Command or Action
Purpose
Step 1
call-manager-fallback

preference-order
]
Example:
Router(config-cm-fallback)# max-dn 15 dual-line

Sets the maximum number of directory numbers (DNs) or
virtual voice ports that can be supported by the router and
activates dual-line mode.
•
max-directory-numbers:
Maximum number of
directory numbers (dns) or virtual voice ports
supported by the router. The maximum number is
platform-dependent. The default is 0. See
Compatibility Information
for further details.
•
dual-line
(Optional). Allows IP phones in
Cisco Unified Communications Manager fallback
mode to have a virtual voice port with two channels.
•
preference
preference-order
(Optional). Sets the
global preference for creating the VoIP dial peers for all
directory numbers that are associated with the primary

the highest preference.

preference
keyword that
sets
alias
command preference values. Setting the
alias
command
preference
keyword allows the default
preference set with the

overridden. See the
“Configuring Call Rerouting”
section on page 129
for more information on using the
max-dn
command with the
alias
command.

Router(config-cm-fallback)# exit
