Summary of Changes


  • V1.0 (2018-06-28): Provide a basic guidance for auto-provisioning Htek IP phones with FreePBX system .


Getting Started


This chapter will show you the basic process of phone's start-up and instructions of the way to get the basic information of the phone. Topics include:


Phone Initialization


After your phone is powered on, the phone will boots up, complete the initialization and check firmware. Please refer to the three phases of the LCD display:

In the process of initializing, the phone will attempts to contact a DHCP server in your network to obtain valid IPv4 network settings (e.g., IP address, subnet mask, default gateway address and DNS address) by default.


Phone Status


After the phone comes up, you can view phone status on phone user interface (LCD) via the following ways:

   1. Press "OK" button twice.

   2. Press the following button one by one: "Menu" -> "Status" -> "information".


Available information of phone status includes:

    1. Network status (e.g., IPv4 status, IP mode, MAC address).

    2. Phone status (e.g., product name, firmware version, MAC address and device certificate status).

    3. Language infomation.


Press "Up" or "Down" to scroll through the list and view the specific information.


Auto-Provisioning your phone


Provisioning via DHCP Option 66,which is mainly used in the situation where Htek phone and FreePBX are in same subnet.
This chapter provides the following instructions of auto-provisioning with FreePBX and show you how to edit the custom provision template on FreePBX. Topics include:

Auto Provision via RPS

Provision via DHCP Option 66

Edit custom provision

Provision via RPS

Provision the IP Phone via RPS is a convenience way.

When the IP Phone start up , default it will send 'Get' message to the RPS server, if the phone's MAC address is assigned on the RPS Server previously, the RPS server will send the preset URL of the configure server to IP Phone.

The work process of RPS show below. And more information about how to use RPS, please refer to these documents fm.htek.com/rs/rps.zip .

Provisioning via DHCP Option 66

Over View


If your network will not have IP connectivity to the Internet, you can use the "Option 66" feature built inside your company DHCP server to auto-provision your Htek phones.  
This requires the IT administrator to insert the IP address/FQDN of the FreePBX server into the company router, under the "Option 66" parameter of the DHCP settings. This procedure is required only once,this procedure is beneficial for mass deployments.

Examples of valid URIs, showing the URL with port would be:
http://HTTP Username:HTTP Password:83(http://192.168.0.8:83)
https://HTTP(s) Username:HTTP(s) Password:1443(https://192.168.0.8:1443)
(Note: http username & password could found in FreePBX server Admin > Provisioning Protocols.)

After the phone powers on and retrieves an IP Address from the DHCP server, 'Option 66' will send the location details of the FreePBX server, which is recognized by the phone. 
If your phone don't turn on the button of DHCP Option 66,login in the phone's webpage,
Click on Management->Auto Provision,Allow DHCP Option :66 and To Override Server set to Yes.(Note that the factory default value of the phone Option 66 is on.)


This is common in typical small office routers. If your router's DHCP server support "Option 66".Then, Provisioning via DHCP Option 66 is a good choice to provision your phones.

Operating Instructions


Obtain End-Point-Manager IP Address


In order for EPM to be able to commiunicate with the phone(s),it must be configured with the same IP address as your FreePBX server.
You can obtain the IP Address of EPM within the EPM Global Settings:
1. Log into your PBX GUI.
2. Under the Settings section, choose EndPoint Manager.

3. Navigate to the Global Settings section of EPM from the right nav bar.


4. Define the Internal IP Address or FQDN that phones will connect to when local to the PBX.


5. Also take note what port you have HTTP Provisioning setup on as that port needs to be accessible for your phone to receive its configurations.
6. Press the Save Global button.


Create a proper template


1. In the right nav menu, under Brands, click on Htek.
 


2. Click on the New Template button at the top to create a new template.

 


3. Give the template a Name. For the Destination Address, choose either the Internal or External option. This will pull in the IP address that you entered in the Global Settings section earlier.

   


4. Define your Time Zone and if you want Daylight Savings time mode to be enabled.

    


5. Define what Provision Server Protocol you want to use to have your phones receive their config files:

          • TFTP should be used when phones are local to the PBX, as it's easy to use and requires no setup. 

          • HTTP should be used for local or remote phones and is easy to use and required no other setup.  The default HTTP port used for phone configs is port 83 but may be different on your PBX.  You can view the port 

            that is currently setup for HTTP in the Global Settings section we just went through above. 


         
6. Press the Save Template button when done.


Configuring Buttons on your Phone

Line Key Types


Line keys can be set up in EndPoint Manager with the following options.

Configuring Line Buttons


1. Go into EndPoint Manager in your PBX and choose the Htek brand in the menu.


2. Click on the template in EndPoint Manager that you want to change a button for.


3. Scroll to Available Phones below and select the relevant template that you wanted.


4. Select a model number you want to add manage buttons for.


5. Make your Line Key button changes.  


6. Save the Model using the Save Model button.


7. You now need to update the phone configuration file. Choose an option and click the Apply button. The three options at the bottom of the template are:

    • Save- This will only save your changes into the PBX database. It will not write out new config files for the phones that are using this template as mapped in the Extension Mapping section of End Point Manager.  

    • Save and Rebuild Config(s)- This will save your changes to the PBX Database and also write out new config files for the phones that are using this template as mapped in the Extension Mapping section of End Point 

      Manager. The phones do not retrieve the updates.

    • Save, Rebuild Config(s) and Update Phones- This will save changes into the PBX database, write out new config files for the phones, and also immediately update any phones that are mapped to use this template and

      currently registered to the PBX. This may cause the phones to reboot.


8. You can optionally change the label name for any button type except Line. The Label is the name that will be shown on your phone screen for that button.  

    • When choosing the Line type, the label name will be whatever you defined in the Line Label section of the phone Template Settings. The default is to show the extension number of the device. You can change this to 

      show the name instead, or both name and extension number.  


9. You can also drag the button to be in a different spot. Left click on the button and while holding down your left mouse drag the button to a different spot and release it. In our example we will drag Button 6 up toward the

    top to make it button 3 on the phone. The button number will not change until you save the model.

 


Logging in with your Phone

Automatic Configuration process


1. When the phone contacts your PBX it will communicate with the End-Point-Manager (EPM) module inside. 
2. EPM will detect any Htek phone that is requesting configuration and if the MAC Address has already been setup in EPM Extension Mapping it will use the configuration for that phone.  
3. The factory default password of the phone is 'admin' however after connecting to FreePBX the password will become the admin password that is defined in the Global Settings of EPM which by default is 222222.  (This password can be changed under the 'Global' settings of End Point Manager). The admin password can also be used as the login password for the phone if you do not know your voicemail password or do not have voicemail setup for your extension. 
4. Below is a screenshot of what the phone will display upon initial configuration.

 

Note: The above 262 and other settings are just an example . Your phone will display the extension number that the user logged in with.


Edit custom provision template

Over View


Maybe you are not satisfied with the default configuration of auto-provision. Each Htek phone setting provisioned by FreePBX is connect with a P number of Htek template file on FreePBX.

Upgrading Firmware and resetting the phone


This part is to serve as a basic guidance for upgrading firmware and resetting the phone.



Upgrading Firmware


To upgrade firmware via FreePBX


1. Login FreePBX →Setting → EndPoint Manager → Advanced → Firmware Management.
2. Chose the Device Brand which you want to upgrading firmware. The phone must be Provisioned by FreePBX before. In our example,we are going to set up Htek firmware.

3. You will see a list of available firmware versions on the left side.

4. You will need to install firmware into at least one firmware slot. Drag a firmware version from the Available Firmwares list into Firmware Slot 1 or Firmware Slot 2.Below you will see we dragged version 1.04 into slot 1, and version 1.03 into slot      2. Version 1.04 consists of different firmware versions for each model of phone listed below the slot number. In slot 1, we see the firmware for the UC926 phone would be 2.0.4.2.11.

Note: You can remove existing firmware from a slot by dragging it back to the Available Firmwares list. This will allow you to install a different firmware version in that slot.
Then Press the submit button at the bottom of the page.


5. Once you have installed the firmware, you can go into any of your templates and choose which firmware that template should use for the devices that are mapped to your template.

Installing Custom Firmware


1. If you would like to install your own custom firmware for a phone you can drag version 0.00 into slot 1 or 2.  This will reserve that slot for your custom firmware by following the same step above for Installing Firmware.  
2. SSH to your PBX and navigate to /tftpboot/brand/slot and put your firmware in place. Replace /brand with the brand of your phone such as htek and replace /slot with 1 or 2 for slot 1 or slot 2.


Resetting the phone

Troubleshooting


This chapter provides general troubleshooting information to help you solve the problems you might encounter when using your phone. If you require additional information or assistance with your new phone, contact your FreePBX server administrator.

Why is the LCD screen blank?


  1. Ensure that the phone is properly plugged into a functional AC outlet.
  2. Ensure that the phone is plugged into a socket controlled by a switch that is on.
  3. If the phone is plugged into a power strip, try to plug it directly into a wall outlet instead.
  4. If the phone is powered from PoE, ensure that you use a PoE-compliant switch or hub.

Why does the phone display "Network unavailable"?


  1. Ensure that the Ethernet cable is plugged into the Internet port on the phone and the Ethernet cable is not loose.
  2. Ensure that the switch or hub in your network is operational.

Why doesn't the phone display time and date correctly?


Check if you have configured the phone to obtain the time and date from the SNTP server automatically. If the phone fails to connect to the SNTP server, you need to configure the time and date manually.

Why the phone can't upgrading by FreePBX successful?


1. Please check that whether the version of the phone is the latest version on the FreePBX.
2. Locate the folder where holds the Htek firmware on FreePBX. And check whether there is firmware files in the folder.
