user can make and receive calls on that phone using the same personal directory number as on their own desk
phone.
Hunt groups
(ephone-hunt)
Voice-system
features
Hunt groups allow you to direct incoming calls to a specific number (pilot number) to a defined group of extension
numbers. There are four different types of hunt groups: sequential, peer, longest-idle, and parallel. Each type uses
a different strategy to determine the first number that rings for successive calls to the pilot number, as described
later in the table.
ephone-dn
overview
Voice-system
features
You can associate buttons on a phone with a line. Lines are of various types; some allow only a single call,
whereas others allow two or more calls. You can associate a phone with multiple line buttons with multiple lines,
allowing one phone to have multiple numbers. You can also share a given line across multiple phones, allowing
one number to ring multiple phones.
ephone-dn,
overlay
Voice-system
features
Overlaid lines allow you to increase the capacity of a line to up to 25 simultaneous calls. This feature is useful in a
helpdesk- or call center-like setup where calls to a single number are answered by multiple people at different
phones.
Feature access
code (FAC)
Voice-system
features
FACs are special patterns of characters that are dialed from a telephone keypad to invoke particular features. For
example, you might press **1, and then press 2345 to forward all incoming calls to extension 2345. FAC is
typically used only on an analog phone that does not have softkey.
Fax
Users,
phones, and
extensions
The fax feature allows the voicemail system to include fax-machine support using analog (FXS) lines. Fax traffic is
handled using SCCP and pass-through by default, or it can be set up for T.37 or T.38 with support for G2 and G3
speeds.
Fax relay
Voice-system
features
The fax-relay feature allows two fax machines to exchange faxes over an IP network. It recognizes that a call is a
fax and not a voice call, and by doing so it provides a more robust transport of the facsimile data.
Feature ring
Users,
phones, and
extensions
When a phone has more than one line associated with it, you can configure one of the lines with a feature ring.
The feature ring allows you to easily recognize that an incoming call is ringing a specific line.
Fixed holidays
Voice-system
features
The Auto Attendant greetings are controlled by a calendar. You can identify certain days as fixed holidays
because they fall on the same date every year. On holidays the Auto Attendant plays a greeting that is appropriate
for a day when the business is closed.
Fixed line and
feature button
set
Users,
phones, and
extensions
The Cisco Unified IP Phone 7931G has a large number of buttons. You can select from two fixed button-layout
formats to assign functions to certain line buttons on the phone to support key-system phone behavior.
Flash softkey
and FXO
hookflash
Users,
phones, and
extensions
The Flash softkey provides hookflash functions for calls made on analog trunks. Certain PSTN services, such as
three-way calling and call waiting, require hookflash intervention from a phone user. The Flash softkey provides
this function for IP phones.
Forwarding
Users,
phones, and
extensions
Call forwarding diverts calls to an alternative specified number under one or more of the following conditions:
● Always
● Upon no answer
● Upon busy
● When night service is active
FXS (analog)
ports
Users,
phones, and
extensions
Call processing supports FXS analog phone ports. FXS ports behave like a regular phone line from the phone
company and allow you to connect a regular analog phone or fax machine.
Group call
pickup
Voice-system
features
With group call pickup, you can answer a ringing phone in any pickup group by pressing the GPickUp softkey and
then dialing the pickup group number. If only one pickup group is defined in the Cisco Unified Communications
500 system, you can pick up the call simply by pressing the GPickUp softkey. You do not need to belong to a
pickup group to use this method.
Hairpin call
routing
Voice-system
features
The Cisco Unified Communications 500 supports hairpin call routing. When a call that originally terminated on a
FXO port from the PSTN is transferred or forwarded by a phone back out to the PSTN (for example, an outside
caller makes a call to a Cisco Unified Communications 500 phone and the call is forwarded to the callee’s cell
phone), the application reoriginates the call and routes it back out to the PSTN through another FXO port. This
looping back from and to the PSTN is called hairpinning. Hairpin routing of transferred and forwarded calls also
causes the generation of separate billing records for each call leg, so that the transferred or forwarded call leg is
typically billed to the user who initiates the transfer or forward.
Hardware-
based
conferencing
Voice-system
features
Conferencing allows you to connect three or more parties in a telephone conversation. Conferences can be
hardware- or software-based, depending on the number of parties. Hardware-based Ad Hoc conferencing
(maximum of 8 parties) uses DSPs to allow more parties than software-based Ad Hoc conferencing, which allows
3 parties only. Meet-me hardware-based conferences (maximum of 32 parties) are created by parties calling a
designated conference number. If you configure software-based conferencing, you cannot have meet-me
conferences.
Header-bar
display
Users,
phones, and
extensions
The header-bar display is the text on the top line of the IP phone display.
Historical
reports
Voice-system
features
Historical reports refers to the ability of the Cisco Unified Communications 500 to provide reports about call
activities and application activities on the system.
