paging (ephone-dn)
To set paging numbers that can be called to broadcast an audio page to a group of Cisco IP phones, use
the paging command in ephone-dn configuration mode. To disable this feature, use the no form of this
command.
paging [ip multicast-address port udp-port-number]
no paging [ip multicast-address port udp-port-number]
Syntax Description
Defaults A Cisco IP phone directory number is not configured as a paging number.
Command Modes Ephone-dn configuration
Command History
Usage Guidelines The paging command configures the ephone-dn number to act as an extension number to use to
broadcast audio paging to idle Cisco IP phones. Cisco IP phones must be associated with the paging
directory number (ephone-dn) using the ephone-dn tag number of the paging ephone-dn, or they are
included indirectly through a paging group from another paging ephone-dn.
When the optional ip keyword followed by the multicast-address argument is used, 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 should use a unique
IP multicast address.
ip (Optional) IP multicast.
multicast-address (Optional) IP multicast address to use to multicast voice packets for audio
paging; for example, 224.0.1.1. Note that multicast addresses always take
the form of 224.x.x.x.
port (Optional) User Data Protocol (UDP) port.
udp-port-number (Optional) UDP port number to use in association with the IP multicast
address. The default is the Skinny Client Protocol port 2000.
