Information About Additional Configuration Tasks
Configuring IVR Auto-Attendant
The interactive voice response (IVR) auto-attendant mechanism can support the handling of inbound
calls on Foreign Exchange Office (FXO) ports and outbound calls on Foreign Exchange Station (FXS)
ports including analog phones configured through the plain old telephone system (POTS) and Cisco IP
phones configured through the Cisco IP phone directory numbers (ephone-dn)—virtual FXS ports. The
tool command line (TCL) scripts play prompts (welcome, phone number, store hours, and store
locations), collect digits, and place calls. The IVR prompts must be downloaded on the Cisco IOS
Telephony Service router’s Flash memory. The IVR prompts require an audio file (.au) format of 8-bit,
u-law, and 8-kHz encoding.
Customized Script
If you want Cisco to develop customized application scripts for you, contact the Developer Support
group at developer-support@cisco.com. This is a fee-based service.
Step 4
Router(config-ephone-dn)# paging [ip
multicast-address port udp-port-number]
Sets paging numbers that can be called 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. IP phones must be
associated with the DN tag number of the paging ephone-dn, or
are included indirectly through a paging group from another
paging ephone-dn.
When the optional keyword ip followed by the multicast-address
argument and port 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.
Step 5
Router(config-ephone-dn)# paging group
paging ephone-dn tag-list, paging
ephone-dn tag-list
Sets the audio paging directory number for a large combined
group. The paging group command is used to combine small sets
of phones associated with individual paging ephone-dns into a
large combined group so that a page can be sent to large numbers
of phones at once.
Note Configure the paging command for all DNs in the group
prior to configuring the paging group command.
Use of paging groups allows phones not only to participate in a
small local paging set (for example, paging to four phones in a
company’s “shipping and receiving” department) but also to
support company-wide paging when needed (for example, by
combining the paging sets for shipping and receiving, with paging
sets for accounting, service, and sales into a paging group).
The argument paging ephone-dn tag-list is a comma-separated list
of paging group tags that are each configured as paging directory
numbers. You can include up to ten paging ephone-dn tags
separated by commas; for example, 4, 6, 7, 8.
