6.2. 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 one second. The phone will speak the address through the
handset earpiece. The physical location of a telephone can be determined by comparing either 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 (Figure 3):
Web Access Username: admin
Web Access Password: admin (Iower case)

connect to other SIP devices without using a SIP server as an
intermediary. This option only exists when using the speed dial
option on the button configuration page. Instead of putting an
extension in these fields, use a IP address.
Note: Some phones do not support placing or receiving calls to a
device rather than a SIP server.
The re-registration interval determines how often the device will
attempt to re-register with the SIP server. Valid values are 1003600 seconds. Some SIP servers may request a device register
more or less often than the value configured here.
If Unregister on Reboot is checked, this device will attempt to send
a remove all register request to the SIP server upon booting. Please
note that if the SIP server does not support this unregister request,
it may cause some problems.

6.10.1. Reboot the Telephone
After a firmware download, the telephone will automatically initiate a reboot.
To manually reboot a Telephone, log in to the web page as instructed in Section 6.2, "Log in to the Configuration
Home Page". Click on reboot on any of the active pages which provide that function.
7. Setting up a TFTP Server
Autoprovisioning requires a TFTP server for hosting the configuration file.
7.1. In a LINUX Environment
To set up a TFTP server on LINUX:
1. Create a directory dedicated to the TFTP server, and move the files to be uploaded to that
directory.
2. Run the following command where /tftpboot/ is the path to the directory you created in
Step 1: the directory that contains the files to be uploaded. For example:
in.tftpd -l -s /tftpboot/your_directory_name
7.2. In a Windows Environment
You can find several options online for setting up a Windows TFTP server. This example explains how to use the
Solarwinds freeware TFTP server.
To set up a TFTP server on Windows:
1. Install and start the software.
2. Select File/Configure/Security tab/Transmit Only.
3. Make a note of the default directory name, and then move the firmware files to be uploaded to
that directory.

8. Discovery Process
Apart from the main application, the device runs a process in the background that listens to discovery requests and can make
changes to the network settings when requested by the client application.
8.1. Accessing webpage functionality without a browser
In addition to the web pages hosted by the internal web server, there is a headless HTML command interface. This
command.cgi interface is meant to be used via scripting and can do things like trigger the relay, reboot the board, or start
and stop calls.
The examples below use the free unix utility wget but any program that can send authenticated http POST commands
should work.
Device Action HTTP Post Command
To trigger the relay (for the
configured delay)
To cause the Device to place a
call to extension 130
To terminate an active call wget --user admin --password admin --post-data "terminate=yes"
To force the Device to reboot wget --user admin --password admin --post-data "reboot=yes" "http://
To play the test audio file wget --user admin --password admin --post-data "test_audio=yes"
To cause the Device to speak
it’s IP address
wget --user admin --password admin --post-data "test_relay=yes"
"http://10.0.3.78/cgi-bin/command.cgi" > /dev/null
wget --user admin --password admin --post-data "call=130" "http://

"http://10.0.3.78/cgi-bin/command.cgi" > /dev/null
Table 13 - Command Interface Post Commands
Type and enter all of each http POST command on one line.
8.2. RESET Switch
a
• The RESET switch is used to get the IP address of the device or reset to factory defaults.
• Press and release the RESET switch within a 5 second window and it will speak the IP address through the on
board speaker.
• Press and hold the RESET switch for 5 seconds and it will indicate it’s restoring defaults and rebooting the
board.
8.3. Testing the hardware
The hardware can be tested using a utility started manually in the debug console. This is called the t test because it is
initiated by pressing the t button at the console.
The t test will show a menu that will change when the user presses buttons or activates inputs.

• Every time the input changes, the output lines will toggle. So when the user presses the RESET switch, in
addition to the change shown on the screen, the relay will trigger, the two optoisolated outputs will be driven, the
LCD will be activated, the LCD will display a change, and the ringer will activate.
• In addition to the general IO, when the t test is started, the audio input and output are looped together.
• When the audio is looped back it replays anything picked up by the microphone out the on board speaker after a
short delay.

9. Frequently Asked Questions
1. How do I update my firmware?
Extract the firmware file from the supplied CD.
2. For additional support or answers to questions not covered on this page, who should I contact?
Contact Guardian Telecom VoIP Technical Support.
3. When dialing the three-digit DTMF tone on the IP phone, I can hear the DTMF-tones coming out of the
speaker of the VoIP device but there is no relay action. The relay works when using the relay test-button
on the configuration software. How do I fix this?
Since the relay test button is working, it seems like the problem results from interfacing with the IP phone
where the DTMF tone is generated. To resolve this problem verify that the DTMF tone on the phone is set to
out-of-band.
4. I was able to register your device with our SIP server, but when I tried to enter a DTMF tone there was
no function.
Make sure your SIP phone is set to 101 for the DTMF payload type (Out of Band RFC2833).
5. After a period of time, my device stops working or is unreachable.
This is a common problem when the re-registration time value is not set correctly.
On a Guardian VoIP device, you need to make sure that the re-registration time value (in minutes) is less
than that is set on the IP-PBX server.
6. On an Asterisk-based VoIP SIP PBX system, the Guardian SIP Device status is "Busy" or
"Unreachable". I have set up both the Guardian VoIP SIP device and the PBX extension information for
the device. I can see the device on the network, am able to PING it, and can bring up the device web page
with a browser. However, when I try to call it from a phone extension, I see the word "Busy" or
"Unreachable" in the Asterisk log.
In the PBX setup page for the extension of the Guardian device, find the Qualify= value and change it to NO.
If the Qualify= value requires a numeric value, then change it to 0.
Note that on some Asterisk systems (such as Intuitive Voice) this value is called the Heartbeat= value. Set
the Heartbeat= value to NO, and then save the settings.
Also, on the product's SIP Setup page, make sure that the Register Expiration (minutes) setting is set to
less than 6 minutes (5 minutes is good) because it needs to be a value less than the Asterisk default value of
6 minutes. Save the settings after changing the Register Expiration (minutes) setting.
7. What type of audio files can be uploaded into the device?
RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz
You can use the free utility 'Audacity' (http://audacity.sourceforge.net/) to convert audio files into a format the
device can recognize.
When you export an audio file with this program, you can save the output as "WAV (Microsoft) signed 16 bit
PCM."
8. On the V2 products, what happens during a firmware upload if the process gets corrupted?
To guard against failed firmware upgrades, units shipped from Guardian Telecom with V.0.0.29 feature a
built-in "fail safe" mechanism.
The Device will store the "TFTP Server IP" and "New Filename" entered on the "Update Firmware" web page.
If, during the boot process, the Device is unable to boot the firmware, it will attempt to download the stored
image from the stored TFTP server.

9. I see in the electrical connection diagram in the users guide that there is a High PIV Ultra Fast
switching diode. Do I need it and if so do you have a source?
This High PIV Ultra Fast switching diode prevents CEMF kick back from an intermediary relay coil when
power is cut and the coil field collapses. You could use an On-Semi MUR105 diode or an IN4007, which is
readily available.

10. We have the Cisco 3550 switch and it looks like the unit is not able to negotiate the power with the
switch. It keeps cycling over and over.
This happens because with default settings, the switch port is resetting power too quickly. Therefore, on the
3550 switch, on the switch port that the unit is attached to, please try adding the following CLI command:
power inline delay shutdown 20 initial 300
That should keep power supplied until the unit can boot up all the way.
11. The Guardian device connected to a Dell Powerconnect 3524P or 3548P port did not stay linked up.
The device comes up, and then it goes down, and then it comes up cycling.
If connected to a Linksys SRW208MP switch, the Guardian device stays up.
Pantel, Cisco, or Linksys PoE endpoints all work on the Dell Powerconnect 3524P.
A user tried hard coding the switch speed/duplex and tried four different Dell Powerconnect 3524P switches.
--- Check to make sure the Dell Powerconnect 3524P has flow control enabled on the port for the Guardian
device to power up properly.
According to Dell:
Flow Control Support (IEEE 802.3X): Flow control enables lower speed devices to communicate with higher
speed devices by requesting that the higher speed device refrains from sending packets. Transmissions are
temporarily halted to prevent buffer overflows. For information on configuring Flow Control for ports or LAGs,
see "Defining Port Configuration" or "Defining LAG Parameters" in the Dell™ PowerConnect™ 35xx
Systems User's Guide.
12. I am unable to connect with the unit when it is plugged into a Cisco SLM 224P switch.
The cables or switch ports that you are connecting to are set in switch or hub mode instead of endpoint
stations. The MDIX setting needs to be changed to MDI since Guardian VoIP products are end stations.
From the Cisco SLM 224P User Guide:
Change to MDI:
MDI / MDIX Displays the Media Dependent Interface (MDI) / Media Dependent Interface with Crossover
(MDIX) status on the port. Hubs and switches are deliberately wired the opposite of the way end stations are
wired, so that when a hub or switch is connected to an end station, a straight through Ethernet cable can be
used, and the pairs are matched up properly. When two hubs or switches are connected to each other, or two
end stations are connected to each other, a crossover cable is used to ensure that the correct pairs are
connected. The possible field values are: - MDIX Use for hubs and switches. - MDI Use for end stations.
