By default when the first extension is added to the phone it automatically assigns two Flexible Buttons as line keys.

When you add the second extension by it will register the extension but wont except calls and there is no way to place calls from the new extension.

Here are the steps required to get the seconds extension working.
This going to assume that the first and second line settings are already configured on the phone.

1) Press the “Phone” button
2) Press the “Flexible Button” key (It looks like a circle with an arrow pointing left)
3) Press the “Menu” button and then “Start Flexible Button Prog Mode”
4) Press an empty box and select “Phone Function”
5) Set the following: Type: DN, Parameter: Ringtone 1 [New Extension Number], Label name: [Label of Extension]
6) Press “OK”. Repeat steps 4 and 5 to add additional line buttons to the same extension or add new extensions
7) When you are done press “Back”

Now you can receive and place calls by using the buttons that were created by the steps above.


Panasonic just confirmed that it will be enabling Bluetooth support on the Panasonic KX-UT670 IP phone.

The firmware is scheduled to be released May 2012.

Panasonic’s website says that the phone is Bluetooth enabled but as posted before(Link) it currently is not.

——Update 01/27/2012——-
A third party Bluetooth USB dongle will be required to enable Bluetooth support.

With the following setup you can simulate SLA (shared line appearance) on the Positron G-124 IP PBX using the Yealink T26 or T28 IP-Phone.

The following is going to assume that the default settings in “PBX Settings” were not changed and you have successfully added at least two phones to the system.

Do the following on all phones:

1) In User Templates make sure “Enable BLF” is checked (apply config if it was changed)
2) In Phone Provisioning click “Configure” on the the phone you want to setup.
3) On Key 1 configure the following: Type: BLF, Line: 1, Value: 701, Pickup Value: *7701
4) Do the same as above on keys 2-4 except increment 701 in both values by one each time (702, 703, etc)
5) Next on Key 10 configure as follows: Type: Call Park, Line: 1, Value: 700
6) Save the settings and reboot the phone

The steps above setup four “Shared Lines” but you can add or subtract the number in step 4.

When speaking on the phone press Key 10 (“Hold”), Key 1 will change to red on all the phones.
Now the call can be “picked up” by any extension in the office.

Many times when setting up the Adtran Total Access 900 Series VoIP Gateway the customer will ask me to force a specific Caller ID for 911.
This way even if the PBX sets a different Caller ID when the emergency call goes out the call will still be routed to the local PSAP.

At first I configured it as follows:
voice trunk T01 type sip
match dnis “911” replace ani “2125551212” name “Emergency”

This worked fine until one customer had a their PBX misconfigured by their vendor and certain calls had no Caller ID.
When this happened and 911 was called the Caller ID was not set with the above rule.
It seems that the Gateway only manipulates the SIP Header when there is value to replace; in this case since there was none it skipped the rule.

I found settings below that can fix this.
For 911 calls only you can use the following:
voice trunk T01 type sip
caller-id-override emergency-outbound 2125551212

The setting “emergency-outbound” is hard coded for 911 calls. If your area has a different emergency number or you want to override none 911 calls with no Caller ID you need to use the if-no-cpn option:
voice trunk T01 type sip
caller-id-override number-inbound 2125551212 if-no-cpn
match dnis “911” replace ani “2125551212” name “Emergency”

Before trying to log in to the phone’s web portal you must enable the web interface:
Press Home -> Menu -> Settings -> Network ->Embedded web -> On

To find the IP of the phone do the following:
Press Home -> Menu -> Settings -> About phone -> Status

The administrator credentials for the Panasonic KX-UT670 is:
username: admin
password: adminpass

Bypassing the passwords on the AOS requires a straight through serial cable to the console port of the unit.
Configure a VT100 session (i.e. PuTTy) using the following settings: 9600 bps, 8 bits, no parity, 1 stop bit and no flow control.
Now apply power to the unit.
As the unit boots you will be given the opportunity to break into bootstrap mode by pressing the ESC key within 5 seconds.
Next type the following:
Bootstrap# bypass passwords
Bootstrap# boot

The system will now boot with the password removed.

Here are the steps to factory reset and upgrade the firmware on the Adtran Total Access 900 Series VoIP Gateway.

– 9 Pin Male Serial cable
– Terminal client (I use PuTTY)
– Ethernet patch cable
– Default config file Link
– A tftp server installed on your computer Link (Make sure that your local firewall is not blocking)
– The latest firmware from Adtran (This is available on Adtran’s site but you will need a free account)

1) Download the firmware from Adtran’s site and place it in the root directory of the tftp sever path
2) Plug the serial port into the Adtran and your computer
3) Plug the patch cable into port ETH 0/1 on the Atran and then into your computer
4) Assign a private static IP to your computer (in this example use
5) Start the terminal client and set it to 9600, 8, 1, None, None (make sure the com port matches your serial port)
6) Plug in the Adtran
7) When prompted (about 5 seconds into the boot sequence) hit Esc to enter the bootstrap; you will now be at the bootstrap# prompt.
8) Type “erase file-system”
9) Type “ip address”
10) Type “copy tftp flash” and you will get the following prompts:
Address of remote host?
Source filename? {the name of the firmware file}
Destination filename? {hit enter}
It will then transfer the file from your PC to the Adtran
11) Rename the default config file to startup-config and repeat step 10 (except the filename is now startup-config) to upload the config file to the Adtran
12) Type “boot system flash {the name of the firmware file} verify”
13) Type “boot”

The system will now boot the new firmware with the default config.
I highly recommend watching the entire boot process and see if there are any error messages.

Make sure it displays something similar to the following:
VoIP DSP 0 Initialize.
Loading Starcore DSP Image from Compressed File.
Boot version: G2.A4.07.04
Application Version: G2.A4.07.04
Starting DSP.
Memory Test…..
Loading Application.
Application Initializing.
DSP is running.

If it does not indicate the DSP is running you probably have a hardware issue.

Once the system is finished booting type “enable” and then “show output-errors”. This will display any config errors during boot.

If you know how to program the AOS from the command prompt you are good to go otherwise you can access the web admin by going to and entering admin and password for the credentials
