Information About Paging

To enable paging, you should understand the following concept:

•Audio Paging

Audio Paging

A paging number can be defined to relay audio pages to a group of designated phones. When a caller dials the paging number (ephone-dn), each idle IP phone that has been configured with the paging number automatically answers using its speakerphone mode. Displays on the phones that answer the page show the caller ID that has been set using the name command under the paging ephone-dn. When the caller finishes speaking the message and hangs up, the phones are returned to their idle states.

Audio paging provides a one-way voice path to the phones that have been designated to receive paging. It does not have a press-to-answer option like the intercom feature. A paging group is created using a dummy ephone-dn, known as the paging ephone-dn, that can be associated with any number of local IP phones. The paging ephone-dn can be dialed from anywhere, including on-net.

After you have created two or more simple paging groups, you can unite them into combined paging groups. By creating combined paging groups, you provide phone users with the flexibility to page a small local paging group (for example, paging four phones in a store's jewelry department) or to page a combined set of several paging groups (for example, by paging a group that consists of both the jewelry department and the accessories department).

The paging mechanism supports audio distribution using IP multicast, replicated unicast, and a mixture of both (so that multicast is used where possible, and unicast is used for specific phones that cannot be reached using multicast).

Figure 38 shows a paging group with two phones.

How to Configure Paging

This section contains the following tasks:

•SCCP: Configuring a Simple Paging Group (required)

•SCCP: Configuring a Combined Paging Group (optional)

•Verifying Paging (optional)

SCCP: Configuring a Simple Paging Group

To set up a paging number that relays incoming pages to a group of phones, perform the following steps.

Restrictions

IP phones do not support multicast at 224.x.x.x addresses.

SUMMARY STEPS

1. enable

2. configure terminal

3. ephone-dn paging-dn-tag

4. number number

5. name name

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

7. end

DETAILED STEPS

Command or Action

Purpose

Step 1

enable
Example:

Router> enable

Enables privileged EXEC mode.

•Enter your password if prompted.

Step 2

configure terminal
Example:

Router# configure terminal

Enters global configuration mode.

Step 3

ephone-dn paging-dn-tag
Example:

Router(config)# ephone-dn 42

Enters ephone-dn configuration mode.

•paging-dn-tag—A unique sequence number that identifies this paging ephone-dn during all configuration tasks. This is the ephone-dn that is dialed to initiate a page. This ephone-dn is not associated with a physical phone. Range is 1 to 288.

Note Do not use the dual-line keyword with this command. Paging ephone-dns cannot be dual-line.

Step 4

number number
Example:

Router(config-ephone-dn)# number 3556

Defines an extension number associated with the paging ephone-dn. This is the number that people call to initiate a page.

Step 5

name name
Example:

Router(config-ephone-dn)# name paging4

Assigns to the paging number a name to appear in caller-ID displays and directories.

Step 6

paging [ip multicast-address port udp-port-number]
Example:

Router(config-ephone-dn)# paging ip 239.1.1.10 port 2000

Specifies that this ephone-dn is to be used to broadcast paging messages to the idle IP phones that are associated with the paging dn-tag. If the optional keywords and arguments are not used, IP phones are paged individually using IP unicast transmission (to a maximum of ten IP phones). The optional keywords and arguments are as follows:

•ip multicast-address port udp-port-number—Specifies multicast broadcast using the specified IP address and UDP port. When multiple paging numbers are configured, each paging number must use a unique IP multicast address. We recommend port 2000 because it is already used for normal non-multicast RTP media streams between phones and the Cisco Unified CME router.

Note IP phones do not support multicast at 224.x.x.x addresses.

Step 7

end
Example:

Router(config-telephony)# end

Returns to privileged EXEC mode.

SCCP: Configuring a Combined Paging Group

To set up a combined paging group consisting of two or more simple paging groups, perform the following steps.

Prerequisites

Simple paging groups must be configured. See the "SCCP: Configuring a Simple Paging Group" section.

SUMMARY STEPS

1. enable

2. configure terminal

3. ephone-dn paging-dn-tag

4. number number

5. name name

6. paging group paging-dn-tag,paging-dn-tag[[,paging-dn-tag]...]

7. exit

8. ephone phone-tag

9. paging-dn paging-dn-tag {multicast | unicast}

10. exit

11. Repeat Step 8 to Step 10 to add additional IP phones to the paging group.

12. end

DETAILED STEPS

Command or Action

Purpose

Step 1

enable
Example:

Router> enable

Enables privileged EXEC mode.

•Enter your password if prompted.

Step 2

configure terminal
Example:

Router# configure terminal

Enters global configuration mode.

Step 3

ephone-dn paging-dn-tag
Example:

Router(config)# ephone-dn 42

Enters ephone-dn configuration mode to create a paging number for a combined paging group.

•paging-dn-tag—A unique sequence number that identifies this paging ephone-dn during all configuration tasks. This is the ephone-dn that is dialed to initiate a page. This ephone-dn is not associated with a physical phone. Range is 1 to 288.

Note Do not use the dual-line keyword with this command. Paging ephone-dns cannot be dual-line.

Step 4

number number
Example:

Router(config-ephone-dn)# number 3556

Defines an extension number associated with the combined group paging ephone-dn. This is the number that people call to initiate a page to the combined group.

Step 5

name name
Example:

Router(config-ephone-dn)# name paging4

(Optional) Assigns to the combined group paging number a name to appear in caller-ID displays and directories.

Step 6

paging group paging-dn-tag,paging-dn-tag [[,paging-dn-tag]...]
Example:

Router(config-ephone-dn)# paging group 20,21

Sets the paging directory number for a combined group. This command combines the individual paging group ephone-dns that you specify into a combined group so that a page can be sent to more than one paging group at a time.

•paging-dn-tag—Unique sequence number associated with the paging number for an individual paging group. List the paging-dn-tags of all the individual groups that you want to include in this combined group, separated by commas. You can include up to ten paging ephone-dn tags in this command.

Note Configure the paging command for all ephone-dns in a paging group before configuring the paging group command for that group.

Step 7

exit
Example:

Router(config-ephone-dn)# exit

Exits ephone-dn configuration mode.

Step 8

ephone phone-tag
Example:

Router(config)# ephone 2

Enters ephone configuration mode to add IP phones to the paging group.

•phone-tag—Unique sequence number of a phone to receive audio pages when the paging ephone-dn is called.

Step 9

paging-dn paging-dn-tag {multicast | unicast}
Example:

Router(config-ephone)# paging-dn 42 multicast

Associates this ephone with an ephone-dn tag that is used for a paging ephone-dn (the number that people call to deliver a page). Note that the paging ephone-dn tag is not associated with a line button on this ephone.

The paging mechanism supports audio distribution using IP multicast, replicated unicast, and a mixture of both (so that multicast is used where possible and unicast is allowed to specific phones that cannot be reached through multicast).

•paging-dn-tag—Unique sequence number for a paging ephone-dn.

•multicast—(Optional) Multicast paging for groups. By default, paging is transmitted to the Cisco Unified IP phone using multicast.

•unicast—(Optional) Unicast paging for a single Cisco Unified IP phone. This keyword indicates that the Cisco Unified IP phone is not capable of receiving paging through multicast and requests that the phone receive paging through a unicast transmission directed to the individual phone.

Note The number of phones supported through unicast is limited to a maximum of ten phones.

Step 10

exit
Example:

Router(config-ephone)# exit

Exits ephone configuration mode.

Step 11

Repeat Step 8 to Step 10 to add additional IP phones to a paging group.

—

Step 12

end
Example:

Router(config-telephony)# end

Returns to privileged EXEC mode.

Verifying Paging

Step 1 Use the show running-config command to display the running configuration. Paging ephone-dns are listed in the ephone-dn portion of the output. Phones that belong to paging groups are listed in the ephone part of the output.
Router# show running-config
ephone-dn  48

Step 2 Use the show telephony-service ephone-dn and show telephony-service ephone commands to display only the configuration information for ephone-dns and ephones.

Configuration Examples for Paging

This section contains the following examples:

•Simple Paging Group: Example

•Combined Paging Groups: Example

Simple Paging Group: Example

The following example sets up an ephone-dn for multicast paging. This example creates a paging number for 5001 on ephone-dn 22 and adds ephone 4 as a member of the paging set. Multicast is set for the paging-dn.
ephone-dn 22 
 name Paging Shipping 
 number 5001 
 paging ip 239.1.1.10 port 2000 
ephone 4 
 mac-address 0030.94c3.8724 
 button 1:1 2:2 
 paging-dn 22 multicast 
In this example, paging calls to 2000 are multicast to Cisco Unified IP phones 1 and 2, and paging calls to 2001 go to Cisco Unified IP phones 3 and 4. Note that the paging ephone-dns (20 and 21) are not assigned to any phone buttons.
ephone-dn 20
 number 2000
 paging ip 239.0.1.20 port 2000
ephone-dn 21
 number 2001
 paging ip 239.0.1.21 port 2000
ephone 1
 mac-address 3662.024.6ae2
 button 1:1
 paging-dn 20
ephone 2
 mac-address 9387.678.2873
 button 1:2

 button 1:3
 paging-dn 21
ephone 4
 mac-address 4398.b694.456
 button 1:4
 paging-dn 21
Combined Paging Groups: Example

This example sets the following paging behavior:

•When extension 2000 is dialed, a page is sent to ephones 1 and 2 (single paging group).

•When extension 2001 is dialed, a page is sent to ephones 3 and 4 (single paging group).

•When extension 2002 is dialed, a page is sent to ephones 1, 2, 3, 4, and 5 (combined paging group).

Ephones 1 and 2 are included in paging ephone-dn 22 through the membership of ephone-dn 20 in the combined paging group. Ephones 3 and 4 are included in paging ephone-dn 22 through membership of ephone-dn 21 in the combined paging group. Ephone 5 is directly subscribed to paging-dn 22.

Where to Go Next

Intercom

The intercom feature is similar to paging because it allows a phone user to deliver an audio message to a phone without the called party having to answer. The intercom feature is different than paging because the audio path between the caller and the called party is a dedicated audio path and because the called party can respond to the caller. See "Configuring Intercom Lines" on page 915.

Speed Dial

Phone users who make frequent pages may want to include the paging ephone-dn numbers in their list of speed-dial numbers. See "Configuring Speed Dial" on page 1063.
