Chapter 5 Command Reference
number (ephone-dn)
Examples The following example shows that 5001 is set as the primary extension number for a Cisco IP phone and
0 as the secondary number. This action allows the telephone number 5001 to act as a regular extension
number and also to act as the operator line such that callers who dial 0 are routed to the phone line with
extension number 5001.
Router(config)# ephone-dn 1
Router(config-ephone-dn)# number 5001 secondary 0
In the following example, 5001 is set as the primary extension number for a Cisco IP phone and “500.”
(the number 500 followed by a decimal point) is set as the secondary number. This action allows any
calls to extension numbers in the range from 5000 to 5009 to be routed to extension 5001 in the event
that the actual extension number dialed cannot be found. For example, IP phones may be active in the
system with lines that correspond to 5001, 5002, 5004, 5005, and 5009. A call to 5003 or 5006 to 5009
would be unable to locate a phone with the 5003 or 5006 to 5008 extensions, so the call would be routed
to extension 5001.
Router(config-ephone-dn)# number 5001 secondary 500.
