Applies to Aastra 6751i, 6753i, 6755i, 6757i, 6730i, 6731i, 6739i

Aastra 67i Series

Step 1: Download Firmware & Copy to Provisioning Directory

These phones have been tested with 3CX Phone System V15 SP1 with the following firmware only:

  • Aastra 6751i - Firmware 2.6.0.2019
  • Aastra 6753i - Firmware 3.3.1.4305
  • Aastra 6755i - Firmware 3.3.1.4305
  • Aastra 6757i - Firmware 3.3.1.4305
  • Aastra 6730i - Firmware 3.3.1.4305
  • Aastra 6731i - Firmware 3.3.1.4305
  • Aastra 6739i - Firmware 3.3.1.4305

Therefore you need to ensure that the phones are running this firmware. To do this:

  1. Download the Aastra firmware and language files here. 
  2. Find the provisioning folder of your 3CX Install – by default it is something like:

    C:\ProgramData\3CX\Instance1\Data\Http\Interface\provisioning\XXXXXX.

    Where
    XXXXXX is the randomly generated folder name of 8 to 12 characters.
  3. Place the hole content of the zip into this folder.

Step 2: Factory Reset your Aastra IP Phone

Before provisioning the IP phone, the phone must be brought back to factory defaults in case the device has residual settings of a previous configuration.

There are 2 ways for doing this depending on whether you know the admin password or not.

If you know the Admin Password

Aastra 6 series - Reset if you know the Admin Password

  1. Press “Setting”:
  2. Press “Admin Menu (5)” (using default pass: 22222) > “Factory Defaults (4)” > “Restore Defaults.”
  3. After the restart, your phone will be successfully reset.

If you do not know the Admin Password

  1. Download the most recent firmware for your phone version and unzip the actual firmware file under the root location (ex: C:\tftp).

Aastra 6 series - Factory Reset if you do not know the Admin Password

  1. Download and install PumpKIN TFTP application.
  2. Connect an ethernet cable from the “PC” port on the phone directly to your machine:

Aastra 6 series - Web Recovery mode

  • By holding down keys “1” and “#” plug in the Power DC on the phone and boot it up until it gets in Web Recovery mode.

Aastra 6 series - IPv4

  • As soon as the IP address appears (ex: 192.168.9.21), configure your local machine with Static IP address to be in the same subnet (ex: 192.168.9.22).
  1. Start TFTP, select “Option menu” > “Server” tab, and under “TFTP download path” point towards the location of your firmware folder (ex: C:\tftp).

Aastra 6 series - TFTP Download

  1. Press “OK” and make sure the check box “Server is running” is ticked.
  2. Point your web browser to the IP address displayed on the phone:
  • “Filename” = firmware file with its extension type ONLY (ex: 51.st), “Upgrade Type” = “Firmware”, “Download Protocol” = “TFTP”, “TFTP Server” = IP address of your local machine where firmware is located and TFTP Server “PumpKIN” is waiting to accept connection and send file (ex: 192.168.9.22),

Aastra 6 series - IP Phone Recovery

  • Press “Download Firmware” button to complete the process.

Logging into the IP Phone web interface

  • Phones previously provisioned via 3CX - If the phone was previously provisioned via 3CX, then you can go to the phones web interface from the management console, PROVIDED THEY ARE ON THE SAME NETWORK! Use the user name and password configured in the management console.
  • Phones not provisioned or provisioned on another system - You will have to obtain the IP via the phone interface and use that. Ensure that you change the default user name and password in the phone (in some cases admin admin!) to something A LOT more secure.

Retrieve information from your 3CX Installation

Retrieve information from your 3CX Installation

  1. Go to the “User” for which you want to add the phone.
  2. Go to the “IP Phone” tab. Click “Configure a phone” to add a phone.
  3. Select the option “Outside the Office” and click “Next”.
  4. Select “Normal Phone” and enable the option to “Configure your phone manually without provisioning”
  5. Now, choose the router phone behind through which this phone will connect.
  6. A pop-up window will appear with the Authentication ID and Password. Depending on your installation you will also see:
  1. If on the local network: The 3CX Phone System FQDN and Port number
  2. If in the cloud: The SBC or Router phone’s IP address and Port number.  

        Take a note of them.
