What is meant by common area phone?  In the context of this blog a common area phone is a Polycom VVX located in an area such as a cafeteria, hotel/office lobby or even a security entrance phone.  It is a VVX located in an area where multiple people, whether authorized users or not, have access to the phone and the phone is not dedicated to a specific user. 

If you are in the process of deploying a phone in a common area you will most likely want to disable some of the default features, functions and physical ports on the VVX.  This article will show you how to do the following:


  1. Disable physical ports on the phone such as the USB and PC ports
  2. Disable the speakerphone hard key and speakerphone functionality
  3. Disable the Home hard key to limit access to menus such as the Settings menu
  4. Remove and/or limit soft key functions (New Call, Sign Out, etc.)
  5. Disable additional features of the VVX

Here are the settings to disable each of the above features/functions/keys:


  1. Disable physical ports:

device.set = 1 = Disabled

device.auxPort.enable.set = 1

device.auxPort.enable = 0

feature.usbTop.power.enabled= 0

feature.usbRear.power.enabled = 0


  1. Disable the speakerphone:

up.handsfreeMode = 0


  1. Disable the Home hard key:

key.26.function.prim = null


  1. Remove default soft keys:

feature.enhancedFeatureKeys.enabled = 1

softkey.feature.basicCallmanagement.redundant = 0

softkey.feature.forward = 0

softkey.feature.simplifiedSignIn = 0

softkey.feature.mystatus = 0

softkey.feature.buddies = 0

softkey.feature.newcall = 0

softkey.feature.doNotDisturb = 0


  1. Disable additional features such as call recording, picture frames and video capability:

video.enable = 0

diags.pcap.enabled = 0

feature.callRecording.enabled = 0

feature.pictureFrame.enabled = 0

dir.local.readonly = 1


Here are some graphics that depict the before and after:

Thanks for putting this together. This is exactly what I was looking for. I put your configuration in place and all is working the way we need it to.

Hi Emilio,

This is already an older post but I have one small question.

When pressing and holding a speed dial key (empty or not) the key can be editted and this can be saved.

For a common area phone this is not OK, as no one should be able to mess with the phone config.

Is there an option to disable the editting of Speed Dials by keeping the key pressed down for 2 seconds.


regards, Paul

After some digging through the Admin Guide I found two possible solutions for this:


dir.local.readonly = "1"


This way configured speeddials can't be edited anymore.

Strange thing is that when readOnly="0" and passwordProtected="1" you can't edit the key, you are not prompted for a password, 


I disabled all other speeddial keys (unconfigured) like this:


key.52.function.prim = "null"

And I thought this would lock the phone down completely.


But even when readOnly="1" it is still possible to add local contacts from a directory, read on...


I do want the people to be able to search the SfB addressbook, and for that I have enabled SfB search on the home screen (and disabled all other buttons) via this function:



Now, when going into the SfB directory and searching for someone you can press <more>, <add to Contacts> and you just created an extra speed dial on a CAP.


I have no clue how to disable this loophole except by removing access to the SfB addressbook.

If I find a solution I will post it here.
