Command History
Usage Guidelines The paging-dn command sets an audio paging directory number (DN) for each Cisco IP phone. The
audio paging feature operates in a fashion similar to intercom, but provides only one-way voice, with no
press-to-answer option. A DN is created, which is associated with a certain number of local IP phones.
The paging extension number is configured using the existing number command in ephone-dn
configuration mode. Multiple paging DNs can be supported for each system. The paging number can be
dialed from anywhere, including on-net calls. The paging audio stream is heard on all selected Cisco IP
paging-dn-number-tag Directory tag number of the paging directory number (ephone-dn)
to associate with the Cisco IP phone. Paging calls to the specified
ephone-dn sends the page to the Cisco IP phone.
multicast Multicast paging for groups. By default, audio paging is sent to
the Cisco IP phone using multicast.
unicast Unicast paging for a single Cisco IP phone. This keyword
indicates that the Cisco IP phone cannot receive audio paging
through multicast and requests that the phone receives the audio
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.
