Overview of Aastra's Phones

Aastra makes a very popular series of SIP phones that work with Asterisk and FreePBX.  

Current models include the 673xi series, the 675xi series, the 686xi series, and the older 9000i series.

The most popular Aastra phones are the 6730i (an entry level phone with no POE), the 6731i (same as 6730i, but with POE), the 6757i (a full featured executive phone with a large display, lots of buttons, and POE), and the 6737i (same as the 6757i, but with gigabit Ethernet).

The 6757i and 6737i phones come with stands that hold the phones at a low angle.  Aastra sells a high-angle stand for these phones separately.

Using an Aastra Phone with FreePBX/Asterisk

To use an Aastra phone with FreePBX, you must set-up an Extension in FreePBX using the Extensions Module Module.  When you do so, you will select an extension number and password which the phone will use to register to your FreePBX system.

Next you must configure the Aastra phone to connect to your FreePBX system.

Configuring an Aastra Phone using the web interface

The easiest way to configure a single Aastra phone is to connect to the phone using it's web interface.  When you connect an Aastra phone to your network and power it up, it will obtain an IP address from your DHCP Server (in most cases, your router).

To find out the IP address, hit Options, 3, 1 on your phone.

Using a web browser, type in the IP address.  You will be asked for a username and password.  The default username for an Aastra phone's web interface is admin, and the default password is 22222.  

Go to the Global SIP page on the phone's web interface, and set the Phone Number and Authentication Name fields to your extension #, Password field to the extension password (NOT the voicemail password), and Proxy Server and Registrar Server to your PBX's IP address. Save and reboot, and your phone should work.

Configuring an Aastra Phone to download configuration files

If you want to make advanced configuration changes or configure a large number of phones, you may find it easier to configure the phones either using the EndPoint Manager Module (a commercial module available for purchase from FreePBX) or by creating your own configuration files in the /tftpboot directory of your FreePBX.

When an Aastra phone first boots up, it will query your DHCP server for an IP address to use.  It will also ask your DHCP server if it supports "Option 66."  If your DHCP Server does, the Aastra phone will obtain the information set in Option 66 and use it to attempt to download a configuration file from the source designated.  In most cases, you'll want to configure your DHCP Server to supply the following:


Note:  Replace with the IP address of your FreePBX machine.

Now, reboot each of your phones (Options, 6) and during boot stage, they should obtain an IP address and automatically configure themselves to download configuration data from the configuration files.

If your router does not support DHCP Option 66, then you'll need to manually configure each Aastra to download the configuration files from you FreePBX install.  Follow the instructions above to gain access to the web interface and then click on "Configuration Server" on the left hand side of the screen (towards the bottom).  In the Configuration Server Settings page, make the following changes:


Download Protocol:  TFTP
TFTP Server:
Note:  Replace with the IP address of your FreePBX machine.
Now click "Save Settings" at the bottom.

Creating Configuration Files

Most distros that include FreePBX and Asterisk (including the FreePBX Distro) includes a TFTP server that will respond to TFTP requests by supplying files contained in the /tftpboot folder.  

When an Aastra phone attempts to download configuration files, it looks for two files:




(where MACADDRESS is the MAC address of the phone in upper case, such as 00085D2CFFFF.cfg).

Optionally, the phone can also download a company directory and a private directory.

Both of these files are text files that contain configuration parameters that are used to configure the phones.  Configuration parameters are typically a word or group of words, a colon, and a value. Any line that begins with a # is a comment and will have no effect.  You can place any configuration parameter into either aastra.cfg or the MACADDRESS.cfg file.  Parameters contained in aastra.cfg will be loaded by every phone, while parameters in MACADDRESS.cfg will be loaded only by the phone that has that particular MACADDRESS.  If a parameter is duplicated in both the aastra.cfg and the MACADDRESS.cfg file, the parameter in the MACADDRESS.cfg file will control.  Changes made using the phone interface will control over any configuration file parameter, until the phone is reset.  A phone will not load any configuration parameters unless it finds the aastra.cfg file (which can be empty).

To create the configuration files, login to your PBX's command prompt and type the following:

cd /tftpboot

nano aastra.cfg

Now insert whatever information you want to appear in the configuration file, and then hit CTRL-X and then Y to save and exit.  Repeat the above commands with the MACADDRESS.cfg in place of aastra.cfg in order to create a phone specific configuration file.

Create configuration files from the web interface

You can create a configuration file (or find the proper value for a particular configuration entry) from the web interface.  Start by configuring your Aastra phone from the web interface.  When you're done, click on "Troubleshooting" on the left hand side of the screen towards, the bottom.  Scroll down to "Support Information," and then click the "Save As" button to the right of "Get local.cfg."  This will download a file to your computer called local.cfg with all the entries that you configured using the web interface.

Updating the firmware

Aastra provides firmware files for download here:

For the Aastra 6730i, 6731i, and 6757i, we recommend Firmware version 2.6.

Firmware updates can be installed by placing the firmware files into the /tftpboot folder along with file named aastra.cfg (it can be empty), configuring the phones to obtain configuration files from your PBX (see above), and then rebooting the phones.

Rebooting the phones

To reboot most Aastra phones, pull the power or hit Options, 6, 1.

Alert Info


A number of FreePBX call flow objects can set an "Alert Info" field to customize the resulting ring generated by phones. For example, a ring group can have an alert info field set to "<Bellcore-dr3>" (with the angle brackets) to have calls coming through the ring group ring with a distinctive ring.

Here are the valid alert info ring patterns. Note that the pitch and style of the ring do not change. The only change is the ring length and ring pattern.

This was tested with Aastra 6737i phones.


Alert Info stringRing pattern
<Bellcore-dr1>this is the regular ring (one long ring)
<Bellcore-dr2>one medium length ring + one medium length ring
<Bellcore-dr3>one short ring + one short ring + one medium length ring
<Bellcore-dr4>one short ring + one medium length ring + one short ring
<Bellcore-dr5>one short ring + silence for remainder of normal ring time

You can find more information about configuration file options in the Aastra Administration Guide for your phone and firmware:
