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 speaker-phone 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.

Audio Paging

Paging

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 35: Paging Group, on page 856

shows a paging group with two phones.

Paging Group Support for Cisco Unified SIP IP Phones

Paging Group Support for Cisco Unified SIP IP Phones

Paging provides a one-way voice path from the paging phone to the paged phone. The paged phone automatically answers the page in speaker-phone mode with Mute activated.

The paged phone receives a page when it is idle or busy. When it is busy with a connected call, the user of the paged phone can hear both the active conversation and whisper paging.

Before Cisco Unified CME 9.0, you can specify a paging-dn tag and dial the paging extension number to page the Cisco Unified SCCP IP phone associated with the paging-dn tag or paging group using the paging-dn command in ephone or ephone-template configuration mode. You can also page a combined paging group composed of two or more previously established paging groups of Cisco Unified SCCP IP phone directory numbers using the paging group command in ephone-dn configuration mode.

In Cisco Unified CME 9.0 and later versions, support is extended so that you can specify a paging-dn tag and dial the paging extension number to page the Cisco Unified SIP IP phone associated with the paging-dn tag or paging group using the paging-dn command in voice register pool or voice register template configuration mode. Paging on Cisco Unified SIP IP phones support both unicast and multicast paging in the same way that these features are supported on Cisco Unified SCCP IP Phones.

In Cisco Unified CME 9.0 and later versions, support is also extended so that you can create a combined paging group composed of two or more previously established paging groups of ephone and voice register directory numbers using the same paging group command used for paging groups of Cisco Unified SCCP

IP phone directory numbers.

Note

The paging port for Cisco Unified SIP IP phones is an even number from 20480 to 32768. If you enter a wrong port number, a SIP REFER message request is sent to the IP phone but the Cisco Unified SIP IP phone is not paged.

With a paging-dn, there is only one paging endpoint and there is only one paging number for both Cisco

Unified SCCP and Cisco Unified SIP IP phones. However, when paging to a Cisco Unified SIP shared line, each phone on the shared line is treated separately.

A phone that can be paged by two paging-dns receives the page from the first paging-dn and ignores the page from the second paging-dn. When the first paging-dn is disconnected, the phone can receive the page from the second paging-dn.

The paging group support for Cisco Unified SIP IP phones uses an ephone paging-dn to dial the paging number before branching out to each Cisco Unified SCCP and Cisco Unified SIP IP phone.

The show ephone-dn paging command displays which paging-dn is specified and which phone is being paged.

Because paging is not considered a call, a paging phone that is in a connected state can press another line to make a call using the phone’s softkeys.

The Cisco Unified SIP IP phone Paging feature also supports:

• multicast paging (default)

• unicast paging

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.

Example for Configuring a Combined Paging Group of Cisco Unified SIP IP

Phones and Cisco Unified SCCP IP Phones

The following example shows how to configure a combined paging group composed of Cisco Unified SIP IP phones and Cisco Unified SCCP IP phones.

In the following configuration tasks, paging sets 20 and 21 are defined and then combined into paging group

22. Paging set 20 has a paging extension of 2000. When someone dials extension 2000 to deliver a page, the page is sent to Cisco Unified SCCP IP phones (ephones) 1 and 2. Paging set 21 has a paging extension of

2001. When someone dials extension 2001 to deliver a page, the page is sent to ephones 3 and 4. Paging group

22 combines sets 20 and 21, and when someone dials its paging extension, 2002, the page is sent to all the phones in both sets and to ephone 5, which is directly subscribed to the combined paging group.

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-dn 22 number 2002 paging ip 239.0.2.22 port 2000 paging group 20,21 ephone 1 button 1:1 paging-dn 20 ephone 2 button 1:2 paging-dn 20 ephone 3 button 1:3 paging-dn 21 ephone 4 button 1:4 paging-dn 21 ephone 5 button 1:5 paging-dn 22

The following configuration tasks show how to configure a combined paging group composed of Cisco Unified

SCCP IP phone directory numbers only.

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

2001 is dialed, a page is sent to ephones 3 and 4 (second single paging group). Finally, when extension 2002 is dialed, a page is sent to ephones 1, 2, 3, 4, and 5, producing the combined paging group (composed of the first single paging group, the second single paging group, and ephone 5).

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

In the following configuration tasks, the paging group command is used to configure combined paging groups composed of ephone and voice register directory numbers.

When extension 2000 is dialed, a page is sent to ephones 1 and 2 and voice register pools 1 and 2 (new first single paging group). When extension 2001 is dialed, a page is sent to ephones 3 and 4 and voice register pools 3 and 4 (new second single paging group). Finally, when extension 2002 is dialed, a page is sent to ephones 1, 2, 3, 4, and 5 and voice register pools 1, 2, 3, 4, and 5 (new combined paging group).

Ephones 1 and 2 and voice register pools 1 and 2 are included in paging ephone-dn 22 through the membership of ephone-dn 20 as paging group 20 in the combined paging group. Ephones 3 and 4 and voice register pools

3 and 4 are included in paging ephone-dn 22 through membership of ephone-dn 21 as paging group 21 in the combined paging group. Ephone 5 and voice register pool 5 are directly subscribed to paging-dn 22.

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

Intercom Lines, on page 781

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

Speed Dial, on page 963
