The KX-UT670 has both an EHS (electronic hook switch) and 2.5mm headset port on the side.
Being that the Plantronics CS70n is one of the supported headsets I hooked it up to the phone using the following setup:
Plantronics 3.5mm hook switch port to the Panasonic 3.5mm EHS port
Plantronics RJ9 to Panasonic 2.5mm headset port

When pressing the “hook” button on the Plantronics headset the phone would answer and disconnect after a second.

If the hook switch wire is disconnected the headset works and if the headset wire is disconnected the
hook switch works but it wont work together.

I sent an email to Panasonic and they sent me back the following fix:
The phone doesn’t support both the EHS and 2.5mm headset at the same time.
To use the EHS with the Plantronics headset you must disconnect the handset from the phone, plug a RJ9 cable from the phone to the Plantronics and then plug the handset into the Plantronics.

See the following Power Point Link for the exact setup.


As of this posting Panasonic only officially supports five of this IP Camera with the KX-UT670. Link

All the manual says is that the camera must be set to VGA or 720p.
What it doesn’t tell you is that it only supports H.264.

I tested with the Panasonic WV-NW502S (Retails for over$1,000) and it worked fine.

Hopefully they will add support for their less expensive IP Cameras.

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
