7. Getting Started
The Installation manual for the telephone provides information on installing and connecting the device to the server.
This manual describes the steps required to customize the telephone to suit the individual's preferences.
The Discovery Utility is available on Guardian’s website at https://www.guardiantelecom.com/resources/voip-support/ and
needs to be installed manually by copying the executable file to a local drive.
To access a VoIP phone for programming:
•Install the Guardian Discovery Utility onto the network server or SIP server.
•Start the Utility by double clicking the icon.
•Click on “Refresh List".
•Click on the device to be programmed to highlight it.
•Click on “Launch Browser".
Figure 2 - Startup Screen
8. RESET Switch
The RESET switch is used to get the IP address of the device or to reset to factory defaults.
• To get the IP address of the device press and release the RESET switch within a 5 second window and it will
speak the IP address through the handset earpiece.
• To reset to factory defaults press and hold the RESET switch for more than 10 seconds until it indicates that it is
restoring defaults and rebooting the board.
9. Configure the Telephone Parameters
To configure the Telephone online use a standard web browser.
All Telephones are initially configured with the following default IP settings:
Parameter Factory Default Setting
IP Addressing DHCP
IP Addressa10.10.10.10
Web Access Username admin
Web Access Password admin
Subnet Maska255.0.0.0
Default Gatewaya10.0.0.1
Table 1 - Factory Default Settings
a. Default if there is not a DHCP server present.
When configuring more than one Telephone attach the Telephones to the network and configure one at a time to avoid IP
address conflicts.

9.2. Log in to the Configuration Home Page
1. Open your browser to the Telephone's IP address. If you do not know the IP address, you can use the “Discovery
Utility" to detect all VoIP devices on the network. When opened the Discovery Utility scans the network for VoIP devices,
specifically Guardian VoIP devices.Individually select the device and launch the browser. Another method to obtain the IP
address is to press the RESET switch for approximately three to five seconds. The phone will speak the address through
the handset earpiece. The physical location of a telephone can be determined by comparing the MAC Address, IP
Address or Serial Number shown on the Discovery Utility screen with the information on the unit.
Note:If the network does not have access to a DHCP server, the device will default to an IP address of
10.10.10.10.
Note:Make sure that the PC is on the same IP network as the Telephone.
2. When prompted, use the following default Web Access Username and Web Access Password to access the Home
Page (See Figure 3).
Web Access Username: admin
Web Access Password: admin (Iower case)
3. On the Home Page, review the setup details and navigation buttons described in Table 3.

code (rfc2833).
DTMF Activation Code: This 25 character field can be used a set a DTMF code used to activate the relay.
DTMF Activation Duration (in
seconds):
When the relay is activated with a DTMF code, it will remain active for this duration in
seconds. Valid values are 1-9.
NOTE: A DTMF activation of 0will toggle the relay indefinitely or until the activation
code is sent again.
Activate Relay During Ring:
When this option is enabled the relay will activate when the device has received a call
and is playing a ringtone.
Activate Relay During Night Ring:
When this option is enabled the relay will activate when the device has received a call
to the night ring extension.
Pulse Relay when Ringing:
When a “ring" is present the relay will pulse with a cadence of 2 seconds on, 3
seconds off.

play back the recorded audio. This can be used to test the microphone gain level.
This button will activate the relay for the DTMF activation Duration (in seconds).
When this button is toggled, it will put the device into button test mode. In this mode,
the handset or hands free speaker will play an audio file when a button is pressed on
the device. For normal keypad input (keys 0-9) it will speak the associated file from the
audio configuration page. For the other keypad keys, (*, #, any other function keys) it
will play a DTMF tone while the button is depressed. The button press mode will time
out after 60 seconds.

Web Page Item Description
Stored Network Settings Shows the settings stored in non-volatile memory.
Addressing Mode:
Select either DHCP IP Addressing or Static Addressing by marking the
appropriate radio button. DHCP Addressing mode is enabled on default and the
device will attempt to resolve network addressing with the local DHCP server
upon boot. If DHCP Addressing fails, the device will revert to the last known IP
address or the factory default address if no prior DHCP lease was established.
See Table 1 for factory default settings. Be sure to click Save and Reboot to
store changes when configuring a Static address.
Hostname: This is the hostname provided by the DHCP server. See the DHCP/DNS server
documentation for more information. Enter up to 64 characters.
IP Address: The IPV4 static IP address in standard dotted decimal notation.
Subnet Mask: The IPV4 routing prefix in standard dotted decimal notation.
Default Gateway: This is the node to go to when an IP address does not match any routes in the
routing table. This requires standard quad-dotted decimal notation.
DNS Server 1:
DNS Server 2: The DNS server configuration is used to setup the primary and secondary name servers for the network. These use standard dotted decimal notation.
DHCP Timeout in seconds*:
*A value of –1 will retry
forever
Specify the desired time-out duration (in seconds) that the device will wait for a
response from the DHCP server before reverting back to the stored static IP
address. The stored static IP address may be the last known IP address or the
factory default address if no prior DHCP lease was established. Enter up to 8
characters. A value of -1 will retry forever.
VLAN Settings Shows the current VLAN settings.
VLAN ID (0-4095): Specify the IEEE 802.1Q VLAN ID number. Enter up to 4 digits. Note: The device supports 802.1Q VLAN tagging support. The switch port connected to
the device will need to be in “trunking mode” for the VLAN tags to propagate.
VLAN Priority (0-7): Specify the IEEE 802.1p VLAN priority level. Enter 1 digit. A value of 0 may
cause the VLAN ID tag to be ignored.
