ephone-dn. The audio paging feature operates in a similar fashion to intercom, but provides only

one-way voice, with no press-to-answer option. A DN is created, which associates the IP phone as part

of a paging group.

SUMMARY STEPS

1. ephone-dn dn-tag

2. number number

3. name name

4. paging [ip multicast-address port udp-port-number]

5. exit

6. ephone tag

7. paging-dn paging-dn number-tag {multicast | unicast}

8. Repeat Steps 6 and 7 to add phones to the paging group.

DETAILED STEPS

Command Purpose

Step 1

Router(config)# ephone-dn dn-tag

Enters ephone-dn configuration mode and configures the directory

numbers for the Cisco IP phone lines.

Step 2

Router(config-ephone-dn)# number number

Configures a valid directory number for the Cisco IP phone that

receives paging.

Step 3

Router(config-ephone-dn)# name name

Assigns the paging number a name for display.

Step 4

Router(config-ephone-dn)# paging [ip

multicast-address port udp-port-number]

Sets paging numbers that can be called in order to broadcast an

audio page to a group of Cisco IP phones. The paging command

configures the ephone-dn number to act as an extension number to

broadcast unicast audio paging to idle Cisco IP phones.

When the optional keyword ip followed by the multicast-address

argument and port is configured, the paging is set for multicast

paging. If an IP multicast address is not configured, IP phones are

paged individually using IP unicast transmission (to a maximum of

ten IP phones). The recommended operation is with an IP multicast

address. When multiple paging extensions are configured, each

extension uses a unique IP multicast address.

Step 5

Router(config-ephone-dn)# exit

Exits ephone-dn configuration mode and returns to global

configuration mode.

Step 6

Router(config)# ephone tag

Enters ephone configuration mode to register Cisco IP phones. This

adds IP phones to the paging group.
