How to Configure Cisco IOS Telephony Service
DETAILED STEPS
Configuring Each Cisco IP Phone
Each Cisco IP phone must be configured individually on the Cisco IOS Telephony Service router to
receive support in the LAN environment. You must assign a number to the phone lines by entering the
ephone-dn command and then you configure each physical Cisco IP phone by entering the ephone
command.

Command Purpose
Step 1
Router(config)# ephone-dn dn-tag
Enters ephone-dn configuration mode and
configure the directory numbers for the
Cisco IP phone lines. The maximum directory
number is platform dependent. See the “Memory
Requirements” section on page 1-4.
Step 2
Router(config-ephone-dn)# number number [secondary
number] [no-reg [both | primary]]
Configures a valid number for the Cisco IP phone.
The secondary keyword allows you to associate a
second telephone number with an ephone-dn so
that the IP phone line can be called by dialing
either the main or the secondary phone number.
Unless you specify one of the option keywords
(both or primary) after the no-reg keyword, the
secondary number is not registered.
Step 3
Router(config-ephone-dn)# name name
Configures a username associated with a directory
number.
You must follow the pattern specified in the
directory command in telephony-service
configuration mode to associate the usernames for
the directory. The pattern for the usernames for the
directory is set either with first-name-first or
last-name-first.
