V-9972 Universal Page Interface Configuration Guide
Rev. 3.1
The V-9972 Universal Page Interface accepts input from an FXO (loop start trunk) port, FXS (CO station) port or by IP network using
Session Initiation Protocol (SIP). The output from the V-9972 can be Line Level audio, FXO (loop start signaling) or audio transmitted
over the IP network using Valcom IP protocol. In addition to the basic capabilities, other features are available by license upgrade and
will be discussed in the appropriate sections in which they are configured.
Hardware Settings
The selection of which analog input and analog output will be active is set using DIP switches on the rear panel. These selections are
not configurable through software. The V-9972 must be power cycled for DIP switch changes to take effect.
Page Input (SW 6)
Two RJ11 jacks are provided for connecting the V-9972 to an analog phone port on a PBX, ATA, etc. One of these ports will be selected
as the active port using DIP switch 6. The ports are labeled according to the type of signaling provided. The port labeled FXO is intended
to connect to an FXS port (analog station port) and the port labeled FXS is intended to connect to an FXO (loop start trunk) port. The FXS
port detects off-hook condition and provides dial tone to the circuit. The FXS port can be used with a standard phone or loop-start trunk
port (SW 6 ON). The FXO port is a loop-start trunk port and can be used with a Station Port or FXS on a PBX (SW 6 OFF).
Page Output (SW 1)
The analog output of the V-9972 is accessed by screw terminals labeled One Way Page Out or Talkback Page Out. The One Way Page
Out (SW 1 OFF) provides a standard line-level audio tip/ring output. The Talkback Page Out (SW 1 ON) provides FXO signaling (loop
start trunk) for use with most multizone page controllers. One of these outputs will be selected as the active output using DIP switch 1.
Timeout Settings (SW 2 & 3, SW 4 & 5)
Two options are available for disconnecting calls automatically. The Silence Timeout indicates how many seconds the V-9972 will stay
active after the audio input has stopped. This can be used to disconnect a call after the caller has stopped speaking. Three values are
available with the switch settings; additional options are available in software programming. If set to 0 (SW 2 & 3 both ON), the timeout is disabled in hardware but may be set to a value between 0-600 seconds in software programming.
The Absolute Timeout indicates how many seconds the V-9972 will stay active for any caller. When the timeout setting expires, the
call is disconnected. Three values are available with the switch settings; additional options are available in software
programming. If set to 0 (SW 4 & 5 both ON), the timeout is disabled in hardware but may be set to a value between 0-3600
seconds in software programming.

For access to other features available on the V-9972, additional programming may be done using any of the following methods:
• DTMF tones from a telephone system connected to the FXS or FXO Input port. A single-line phone may be used by itself on
the FXS port.
• Using the Valcom VIP-102B IP Solutions Setup Tool. The tool and reference manual are available for download from
www.valcom.com/vipsetuptool.

• Through the built-in web interface
Access to the web interface or with the VIP-102B Setup tool for programming requires the V-9972 to have a valid IP address.
By default, the V-9972 will try to acquire an IP address using DHCP (Dynamic Host Configuration Protocol) when connected to
the network. Check with the local network administrator to determine what IP address was assigned from DHCP. If DHCP is not
available, the V-9972 will default to an IP address of 192.168.6.207 after 3 minutes. The VIP-102B Setup tool may be used to
discover the IP address, either by using the Scan function or the Network Diagnostics function in the tool. The tool can also be
used to set the IP address using multicast communication. Refer to the VIP-102B Setup tool reference manual for more details.
Using a telephone connected to the analog port on the V-9972 to set the IP address is discussed in the next section.

DTMF Programming
The programming interface using DTMF from a telephone on the Input port provides a limited set of options.
It is very useful for setting the initial IP address so that further programming can be done over the IP network.
Entering DTMF Program Mode
The V-9972 monitors the telephony audio port for the DTMF digits “**” + Pass-code + “*” at any time during a paging
event. Using the default values, this would be **9972*. If the V-9972 detects that sequence, the V-9972 enters into
DTMF Program Mode. The outbound page interface will be disconnected and returned to idle condition.
DTMF Program Mode Acknowledgement
When entering DTMF Program Mode, the V-9972 responds to the user with an acknowledgement tone on the
telephony input. The V-9972 shall then monitor the telephony input for DTMF parameter index combinations per
DTMF Programming Options in the table shown below.
DTMF Programming Timeout
When DTMF programming mode is entered, the absolute timeout time shall be set for the duration of the call to10
minutes, and the silence timeout disabled. If this absolute timeout is reached before the user terminates programming
by hanging up, the V-9972 shall issue a reorder tone to the user and then hang up the telephony connection.
DTMF Program Menu
The DTMF Menu consists of the user keying in two DTMF digits to select the item to be programmed (the parameter
index) and then a variable number of digits to perform the actual setting. To abort the current selection or to
terminate a variable length field, the user will key in a ‘#’. After entry of a successful DTMF parameter index, the
acknowledgement tone is transmitted and the V-9972 enters a state where the parameter value can be entered.
If the DTMF parameter index is invalid, the V-9972 returns a tone to indicate command rejection, and then waits for
the next menu item selection.

VIP-102B IP Solutions Setup Tool
The VIP-102B IP Solutions Setup Tool provides access for programming all of the available software-controlled
functions of the V-9972. The tool is available as a free download from the Valcom web site at https://www.valcom.
com/vipsetuptool. A Reference Manual for the program is also available at the same location.
When first starting the VIP-102B program, the initial screen will prompt to scan the network for available devices.
If the V-9972 has a valid IP address (from DHCP or from DTMF programming, for example), the tool should find the
V-9972 (and any other Valcom IP equipment). Follow the prompts in the VIP-102B tool to scan the found devices
into the tool for further programming. The scanning process is beyond the scope of this document, but full details
are in the VIP-102B tool Reference Manual noted previously.
The VIP-102B Programming tool downloads the programming information from the V-9972. Changes to the
programming are made off-line in the tool, then uploaded back to the V-9972. Until the programming is uploaded,
the V-9972 is not changed.
In the following discussion, some of the Properties and Time programming tabs/screens are not shown, as they are
typical for all Valcom devices and are fully described in the VIP-102B Reference Manual.
After scanning and selecting the discovered devices the V-9972 displays as a Universal Page Interface device type.
The Summary tab shows a read-only view of the basic properties of the device.

The Channels and Group Membership
tabs in the VIP-102B Programming tool are
used if the V-9972 has been upgraded with
the Valcom Gateway license. When used in
combination with other Valcom IP devices,
the information in the Channels tab (such
as Dial Code) would need to be entered
with values appropriate for the overall
installation. The Group Membership
tab is used to assigned this V-9972 to
appropriate Valcom IP Paging groups.
Refer to the VIP-102B Reference Manual
for more information.
The SIP tab is used to enter the necessary
information for theV-9972 to be a
SIP endpoint on a SIP-enabled PBX.
The main fields are described below.
For a full description of all fields, refer
to the VIP-102B Reference Manual.
Transport – Sets the transport protocol to be used for SIP
communications. Selections indicate what transport protocol the
VIP device will accept inbound and which protocol to originate
outbound. “Accept: TCP+UDP, Originate: UDP” is the default.
Other selections allow define UDP to be accepted and originate
with UDP, or allow TCP or UDP to be accepted and originate TCP.
Phone Number – Defines the unique number that is assigned to
this device. The SIP Phone Number, or directory number, is the
number this device will respond to for inbound SIP connections.
Phone Numbers can contain letters, numbers, period (.) or hyphen (-).
Description – The text description of this SIP identity (30 characters maximum). This is for information only.
Authentication Name – The identification used to register with a
SIP server or Proxy. This can also be referred to as a username for
the SIP server.
®
www.valcom.com I 540.563.2000 I 800.825.2661
Secret – The password used with the Authentication Name when
registering with a SIP server.
Realm – The security domain in which the Authentication Name
and Secret are defined. Generally, this field can be left blank unless
required by the SIP server or provider.
SIP Servers – The SIP registrar server(s) to which this endpoint
device will attempt to register. At least one primary (required) and
up to 3 backup servers may be entered. These entries may be an IP
address or server hostnames (if DNS is properly configured on the
Network Tab). The Register checkbox must be selected (checked)
to enable the registration to occur. The DNS SRV can be checked if
the SIP servers are defined using DNS SRV records to provide a list
of SIP servers.

In addition to the basic features, two upgrade licenses can enable more functionality.
Functionality available with license L9972-1 (Enhanced SIP)
Enhanced SIP, Store & Play, Night Ring
• Enables up to 4 individual SIP phone numbers or simultaneous calls using one phone number, or combinations thereof.
• Store & Play must be enabled for multiple call functionality
• Any or all SIP numbers can be provisioned as Night Ring
With the L9972-1 license installed, and with Store and Play enabled on the System tab, the SIP tab will now display four SIP
subtabs that can be programmed for up to four separate SIP extensions. There will also be a new selection named Max
Calls to allow a single SIP phone number to accept simultaneous calls. Each additional call assigned to a phone number will
reduce the available channels to maintain a maximum of four total simultaneous calls for the device.
The L9972-1 license also enables the Night Ring function. A SIP number with Night Ring checked will not answer the
inbound call, but will play a ring tone to its analog output while that SIP call goes unanswered.

The Web Administration Password is the password used to access this web interface for programming.
Default password is admin.
The Network page contains fields for setting the Host and Domain Names for the V-9972 and other IP network values.
The V-9972 is initially set to use DHCP to acquire an IP address from the network. When set for DHCP, other fields will
allow setting a DHCP Timeout and Fallback addresses if DHCP is not successful. The Timeout value sets how long the
V-9972 will attempt to get an address from DHCP, and the Fallback values are the IP address settings the V-9972 will
use if DHCP does not provide an address.
The SIP SDP NAT External IP is used to enter an external (public) IP address that should be substituted in the SIP SDP
data for the IP address of the V-9972. This is typically used when connecting to hosted SIP phone systems when the
local Internet firewall does not handle the SIP NAT translations.
Link Local Name Resolution Service checkbox is an optional selection that enables the V-9972 to send LLMNR packets
onto the network. This can aid in network troubleshooting if necessary.

Inter-Page Timing controls the timing between pages, in seconds The range is 1 to 10.
FXS/FXO Channel Priority sets the priority (Low, Normal or High) of the messages received on the analog interface.
If the analog output is set for Talkback Page Out (FXO), the option to Collect DTMF appears. If selected, the V-9972 will
record DTMF digits keyed in from the phone (up to the Dial Code Length) before recording the voice audio. The Delay
After DTMF Signaling (0-20 seconds) is the amount of time the V-9972 will wait before playing the DTMF codes from
the output connection. After the DTMF is played out, the recorded voice audio will be played.

Accept: UDP, Originate: UDP
Accept: TCP+UDP, Originate: TCP
SIP Channel Priority – (Displays when Store and Play is selected) sets the priority (Low, Normal or High) of the
messages received on this SIP channel.
Phone Number – defines the unique number that is assigned to this device. The SIP Phone Number, or directory
number, is the number this device will respond to for inbound connections. Phone Numbers can contain letters,
numbers, period (.) or dash (-).
Description – is a text description of this SIP identity

Secret – is the password used with the Authentication Name when registering with a SIP server.
Realm – is the security domain in which the Authentication Name and Secret are defined.
CID Name – is the text that will be provided by this endpoint device as the Caller ID information for an outbound
connection to other endpoints. Endpoints with Caller ID display capability will be able to display this information.
CID Number – is the telephone number that will appear on endpoint devices with Caller ID capability.
Primary SIP Proxy and Backup Servers – are the registrar server(s) to which this endpoint device will attempt to
register. You should have at least one primary and up to 3 backup servers. These entries may be an IP address, or, if DNS
is properly configured on the Network Tab, server names. The Primary SIP Proxy Port and Backup Ports are the ports on
the SIP servers on which they listen for SIP communications.
The Register checkbox must be selected (checked) to enable the registration to occur. The DNS SRV can be checked if
using DNS to provide a list of SIP servers to which the V-9972 will attempt to register.
Outbound Proxy – is the device to which SIP communications should be directed to be “proxied”, or forwarded,
to the next segment of the network. This entry may be an IP address, or, if DNS is properly configured on the Network
Tab, a server name and is different from the SIP server entry.
Outbound Port – is the IP port number used for communicating to the Outbound Proxy (see above).
SIP Port –
is the port on which the V-9972 will listen for inbound are the IP port numbers to be used for SIP communications.

RTP Port – is the IP port number used for Real Time Protocol communication. RTP is the protocol used for sending/
receiving audio over the network. This entry should be an even number to conform to industry standards.
Keep Alive Timeout (secs) – Interval in seconds (20 – 3600) that SIP registration is sent to a SIP server
(default 3600 seconds).
Options Timer (secs) – Interval in seconds (0 – 300) that a SIP Options message is sent to the SIP server.
(default 0 disables the option)
Idle Timeout (secs) – is configurable from 0 – 60. If audio packets are no longer received after the set number
of seconds the device will terminate the call. (default 0 disables the timeout.)
Max Call Timer (secs) – is configurable from 0 – 600. The device will terminate the call when the timer reaches
the number of seconds configured. (default 0 disables the timeout) This option is typically used when calls are not
hung up properly.
Night Ring – when checked, this enables this SIP phone number to be used as a Night Ring station. The V-9972 will
not answer the inbound call, but will play a ringback tone to signal that a call is being received. This option is available
with the L9972-1 license.
