Skype for Business / Lync Polycom VVX Manager Version 3

Polycom’s VVX range of phones on Lync/Skype for Business have come a long way in the past few years. The release of version 5.4 has delivered further improvements and new features and moved them into a position of superiority over even Lync Phone Edition devices. Since version 5.4 of VVX software there has been support for remote management features by way of a RESTful web service interface. The VVX Phone Manager takes advantage of this API and allows you to remotely execute various functions of the devices. As of version 3.0 there is also now support for phones that are directly registered to Skype for Business Online!

Polycom VVX Manager Version 3 Features

Polycom VVX Phone Manager 3

Skype for Business Online Support - The VVX Phone Manager as of version 3.0 can now list up users from Skype for Business Online and discover their VVX/Trio devices using the Network IP Discover method (supports users with VVX's and Common Area Phone Devices). The "Connect SfBO" button will connect the PowerShell session to SfB Online. You will need to enter your Office 365 AAD username and credentials to connect. Once connected a green "Online" label will be displayed next to the button and the button’s text will change to "Disconnect SfBO" which you can click to disconnect from SfB Online.

Phone discovery – Phones can be discovered either by automatically querying the Lync/Skype for Business Monitoring database (provided there is a monitoring role deployed in the environment) by pressing the “Discover from Monitoring DB” button. Alternatively, this can be done by entering IP Address ranges and “pinging” contiguous subnet ranges for phones using the “Discover from IP Range” button (format: "" OR "" OR add multiple with comma separation ","). During the discovery process, phones that are logged in to user accounts will be listed in the users list. If the tool finds a VVX handset that is not signed in, it will be added to the user list under the name “VVXNot@LoggedIn_<index number>”. This allows you to use the tool to access these devices even though they are not signed into the system.

Important Note: The VVX Phone Manager Tool uses the registration database within the Lync/Skype for Business monitoring database to determine the IP addresses of phones. However, registrations are only added to this database at the time when a user manually signs in with a PIN or with Domain authentication details. If a user moves a phone to a new subnet or the IP Address changes without signing it out/back in then its new IP Address will not be written to the Monitoring database. So, in some cases, the Monitoring database may not produce a complete list of registered VVX devices. The "Monitoring DB Query Time" value in the "Settings" dialog can be used to extend how far back the Monitoring DB query will go to find VVX registrations. This can help to find phones that haven't been manually signed in for an extended period of time. Or alternatively, the "Discover from IP Range" option can be used to do an exhaustive scan of all subnets if required. 

Export/Import Phone Info – This feature outputs a CSV file that contains all the Users, IPs, Firmware Version, Serial Numbers, Lync/Skype for Business Server, and MAC Address (if available) for all phones. If you select the "More" checkbox you will also get the additional Lync/Skype for Business policy settings for each user (this is slower).

Access Web Interface - Access the web interface of a VVX phone by selecting a user in the user list and clicking the “Web Config” button. This will automatically load the web browser to the phone's web interface.

Pin control – The “Pin…” button will load a dialog that will Set, Test, Lock, Unlock a user’s PIN number.

PIN Dialog

Send Text Messages - Send text messages to be displayed on a Polycom VVX phone. An example of this would be to send a message to warn before a system upgrade or a reboot. Messages are displayed on the screen for 30 seconds.

Example of Message Screen

Note: Sending messages relies on the PUSH interface being enabled on the phone in order to accept the message. See the VVX Requirements section for more detail of this configuration. 

Get More Info – By pressing the “More Info” button you can get extended information about a VVX phone including: Device Info, Call Status, Presence Info, Network Info, Line Info, SIP Status, Network Statistics.

Reboot/Restart Phones – You have the choice of Rebooting or Restarting a single, multiple, or All phones.

Reset Config – You have the option to Reset the Config or Factory Reset the configuration with one or many phones.

Get/Set Config - You can Get or Set any setting in the phone configuration. You simply need to enter the configuration setting name (as you would find in the configuration file eg. log.level.change.hset) and click the Get or Set buttons to view or change the setting's value.

Sign in / Sign out devices (5.7 software required on the phone) - Selecting sign in will open a dialog that allows for either AD Authentication or PIN Authentication. Selecting sign out will sign out the phone from Skype for Business.

Dial / End Call – You can choose to remotely dial a SIP URI (eg. or on a phone by entering a URI and pressing the “Dial” button. If the phone is on a call you can also choose to end the call using the “End Call” button.

Test FTP Config Server - Test your FTP Configuration File server by simply entering the IP address of the FTP server and pressing the “Test FTP” button. The tool will attempt to connect to the FTP server and download information about key files associated with a Polycom configuration server deployment. These include the base configuration file (000000000000.cfg), configuration files in the CONFIG_FILES tag, any MAC address files associated directly with phones, and firmware files (*.sip.ld). The tool will give feedback as to the state of the FTP server.

View Screen – The “Screen…” button will open a dialog that will show you the user's screen. Before the user's screen can be viewed the user must first manually allow access to the Screen Capture feature (this is a security measure so that the user is aware that someone is viewing their screen). This setting within the Basic->Preferences screen will only be made available while the VVX screen dialog is displayed (the tool automatically makes the setting "up.screenCapture.enabled" in the device to turn on this preference setting). When the dialog first loads you will see a screen that looks like this:

VVX Screen Dialog

At this point the user will have to enable the following setting in their phone preferences:

Settings -> Basic -> Preferences -> Screen Capture -> Enabled

Note: In version 2.50 of the tool with Version 5.7 of VVX software this step is not required anymore. The tool will immediately be able to display the screen by using the REST interface to enable the feature.

Now you will be able to see the user's screen and save screenshots of the screen as JPG files if you so desire:
VVX Screen

Command Line Settings – If you would like to load the script with your own specific settings to save time, you can specify these in the command line when loading the script. The format of the parameters are as follows:

Script command line settings:
.\Skype4B-Lync-PolycomVVXManager3.00.ps1 -WebPortInput 443-UseHTTPSInput false-AdminUsernameInput AdminUsername-AdminPasswordInput AdminPassword-PushUsernameInput PUSHUsername-PushPasswordInput PUSHPassword-IPRangeInput “”-OnlineUsernameInput "Password"

Settings Dialog – The “Settings…” button allows you to configure your own passwords, web service port and HTTPS settings for the tool.

Note: Continue reading for definitions of these settings.

Bulk PIN Authentication (New in version 2.50)

The bulk PIN authentication feature allows you to sign in multiple devices (that are currently signed out) using their respective extension and PIN numbers. This feature is useful for if you are deploying a site and require all the phones be logged in the day after the cutover before staff arrive at work. Another scenario might be that you want to sign in new starters phones at the time when you initially set their PIN number to allow them immediate access to their phone.

Phones that are signed out will be displayed in the interface as “VVXNot@LoggedIn_<IPAddress>”. Any device that is in this state will be eligible to be displayed within the Bulk PIN Authentication window when it’s opened. Below is an example of what the Bulk PIN Authentication window looks like when it’s first opened:

Note: You will need the REST API enabled on devices that you want to be displayed in the Bulk Authentication interface.

Once the Bulk PIN Authentication window is open you need to assign Extension and PIN numbers to each device. To do this you can choose to import a CSV file with this information in it to fill in the table. Or you can manually do it with the Extension/PIN text fields and Update Row button. Once you have added Extension and PIN numbers to a row it will change colour to green. Lines that do not have an Extension and PIN will be ignored when you run the Bulk Authentication process.
To use the CSV import you need to create CSV file with the following headers:

MAC Address,Extension,PIN

You will need to know the MAC address of the phone devices to create the CSV file. So it’s important to have good records describing where devices are deployed within the organisation.

After Extensions and PIN numbers have been added for the required devices you click the “Run All” button and the sign in process will begin. The sign in process runs in parallel for all devices. The tool will poll the devices to check if the sign in process has completed. Once finished the results will be reported back for each device in the Result column.

The results can be exported with the “Export Results...” button in CSV format for future records.

Polycom VVX Manager Configuration Requirements

Firmware Requirements

The VVX phone must be at least firmware version 5.4 in order to be controlled by the VVX Phone Manager Tool because this version is the first to support the new REST based management API. If you select a user that has a phone with an older version of software, the tool will display a warning in the Powershell window and give you limited access to features for that user. Note: software version 5.4.0A is required for VVXs connecting to Skype for Business.

VVX Web Server Settings

Since version 5.1 of VVX software, there have some increased security enhancements added to the phones. This increased security will affect your ability to connect to the web interface and web services interface of VVX devices when you are running them in an out-of-the-box configuration. So in order to use this tool you will need to edit some basic configuration settings on your phones (usually done via configuration files).

The following web server settings were added in version 5.1 VVX firmware:

Web Config Mode

Different combinations of these setting will give you access to either HTTP, HTTPS or both at the same time. Below are examples of how to achieve all of these settings:

Example settings:

Note: The config setting httpd.ta.enabled="1" is also required for the 5.7 features to work correctly.

HTTP Web access only:
<!-- HTTP Admin Settings -->
<httpd httpd.enabled="1" httpd.cfg.enabled="1" httpd.cfg.port="80" httpd.cfg.secureTunnelEnabled="0" />

HTTPS Web access only:
<!-- HTTPS Admin Settings -->
<httpd httpd.enabled="1" httpd.cfg.enabled="1" httpd.cfg.secureTunnelPort="443" httpd.cfg.secureTunnelEnabled="1" httpd.cfg.secureTunnelRequired="1" />

Both HTTP and HTTPS web access: 
<!—HTTP and HTTPS Admin Settings -->
<httpd httpd.enabled="1" httpd.cfg.enabled="1" httpd.cfg.port="80" httpd.cfg.secureTunnelEnabled="1" httpd.cfg.secureTunnelPort="443" httpd.cfg.secureTunnelRequired="0" />

Note: If you would like to make the Web Admin harder for people to find, you can change the port number to something different from the default 80 or 443 settings. If you do this, you will need to change the Web Port setting in the settings screen of the tool to match your selected port.

In addition to enabling the web server in the phone you must also change the default password on the device as well. If you do not do this the phone will display errors/warnings on the phone display and web interface (“Default admin password is in use, please contact your administrator”). Passwords can be configured in the configuration file as follows:

<!-- Passwords and Security -->
<device device.auth.localAdminPassword="12345" device.auth.localUserPassword="12345" />

Note: Make these passwords whatever you want them to be, however, they must be different than the default of 456 in order to avoid the warning message being displayed on the phone screen.

After you have changed these settings the web login and phone screen login passwords will be changed. So if your support staff have been trained to enter the default “456” password, don’t forget to tell them that it has changed.

Enable REST API:

Config File Setting:

The following REST API setting must be enabled in order to use the Polycom VVX Manager Tool:

<apps apps.restapi.enabled="1" />

Web Interface Setting:

Settings -> Applications -> REST API

Note: If this setting is not configured you will receive "(404) Not Found" errors when trying to send commands to the phone.

Text Messaging Settings

In order to send messages to VVX phones you need to enable the Push settings in the configuration. You can do this with the following settings:

Config File Settings:
<apps.push apps.push.alertSound="1" apps.push.messageType="5" apps.push.serverRootURL="push" apps.push.password="vvxmanager" apps.push.username="vvxmanager" apps.push.secureTunnelEnabled="1" apps.push.secureTunnelPort="443" apps.push.secureTunnelRequired="0"></apps.push>

  • apps.push.messageType: This sets the level of messages that will be displayed for the phone. The VVX Manager always sets the messages as “critical” so they will always be received. The setting “5” means that all levels of messages will be displayed by the phone.
  • apps.push.serverRootURL: This setting needs to be set to "push". This is used as part of the URI for sending messages to the VVX.
  • apps.push.username: The phones use digest authentication for push connections. The username sent by the tool by default is “vvxmanager”. This can be changed in the Settings dialog in the tool.
  • apps.push.password: The phones use digest authentication for push connections. The password sent by the tool by default is “vvxmanager”. This can be changed in the Settings dialog in the tool.
  • apps.push.alertSound: Play a sound when the message is displayed. This is the standard Polycom sound that you hear when a phone reboots. This can help the user to see the message, as it will only be displayed for 30 seconds.
  • apps.push.secureTunnelEnabled: If 0, HTTPS is disabled for push. If 1, HTTPS is enabled for push.
  • apps.push.secureTunnelPort: Changes the HTTPS port number (default is 443).
  • apps.push.secureTunnelRequired: If 0, HTTPS is not required (ie. HTTP is also available). If 1, HTTPS is required for push (ie. HTTP connection is disabled). Note: if you try to connect using HTTP when this is set to 1 you will receive a "(405) Method Not Allowed" error.

Web Interface Settings:

Settings -> Applications -> PUSH

MAC Address Display

If you want to be able to remotely tell what the MAC address is of a phone (useful when building phone specific config files) from the VVX Phone Manager tool interface without having to open the web config, add the following setting:

<device sec.tagSerialNo="1">
   <prov device.prov.tagSerialNo="1"/>

This will result in the MAC address being included in the device string, eg: “VVX Version: PolycomVVX-VVX_500-UA/”. If you do this, the tool will also check the FTP server for individual MAC address files and tell you which phones have these when the “Test FTP” button is pressed.

Polycom VVX Manager Tool Settings

When connecting from the VVX Phone Manager you need to match the password that you configured in your phone with the tool. The settings can be entered into the tool by pressing the “Settings…” button:
  • REST Username: This setting is always set to “Polycom”.
  • REST Password: This setting needs to match the “device.auth.localAdminPassword” setting in your VVX phone. If the password is wrong and doesn't match your phone setting you will see "(401) Unauthorized" errors being returned from the phone when you try to send it commands.
  • PUSH Username: This setting needs to  match the “apps.push.username” setting in your VVX phone.
  • PUSH Password: This setting needs to match the “apps.push.password” setting in your VVX phone.
  • HTTPS: This needs to match your phone's configuration settings for “httpd.cfg.secureTunnelEnabled”
  • Web Port: This needs to match your phone's configuration settings for either “httpd.cfg.port” for HTTP or “httpd.cfg.secureTunnelPort” for HTTPS.
  • Monitoring DB Query Time: This setting determines how many months back in the monitoring database the tool will look for VVX phone registrations. By default this setting is 6 months, meaning that the IP Address of any VVX phone registered in the past 6 months will be scanned to see if it is still located at that IP Address. This setting can be increased if your VVX phones have not been manually signed out/in for longer than 6 months. Or if you have a site where users are frequently signing in and out of their VVX phones you can reduce this value to save time scanning old IP Addresses for VVXs. The setting can be set between 1-48 months (ie. from 1 month up to 4 years).
  • Discovery Wait Time: This setting allows you to tune the time that the tool will wait for responses from discovery messages sent to phones (setting between 200ms-1000ms). This can be helpful if you are trying to discover phones on a distant subnet with a high levels of latency.

SQL Requirements

In VVX Phone Manager 1.xx there was a requirement that SQL ports were opened on each Front End server for accessing information on phone IP Addresses (which work some of the time). This new version of the tool only requires access to the Monitoring database on the Lync / Skype for Business Backend SQL server in order to discover the IP Addresses of phones signed into the system.

Important Warning About Trio SkypeUSB Mode

Note: Thanks to Greig Sheridan for providing testing of USB mode!

The Trio devices can run in a special mode called SypeUSB mode whereby they basically become a dumb USB device that you connect to a USB port of a PC as an audio device. This mode is turned on using the base profile setting below:


When in this mode the VVX turns off its SIP stack and will not respond to the VVX phone manager. This renders the device un-discoverable so you will not be able to see it in the tool. In addition to this, if you want to convert the device back to the Lync/Skype profile and have it talking SIP again you should do a full file system reset of the device first. It was found that factory defaulting the device sometimes isn’t enough to get the SIP Stack back firing on all cylinders and you might see 404 SIP errors coming back from Trios when trying to discover them with the VVX Phone Manager.

The moral of the story here being that SkypeUSB mode does not work with the VVX Phone Manager. So don’t waste a whole bunch of time trying to figure out debug SkypeUSB mode!

Getting Started with a Polycom VVX Deployment

This article was written under the assumption that you already have VVX phones deployed, and you are now looking to manage them. If you need some more help with the initial deployment part of the process, I can point you to some useful resources:

Jeff Schertz' great post on the different ways to deploy Polycom phones is here: Provisioning Polycom SIP Phones. Greig Sheridan also has a nice post on Optimising the Polycom VVX for Lync that you might want to check out too.

If you would like to know more about what is supported on Lync with VVX phones and setting up a FTP server to support Polycom Configuration files on Lync, go to the Polycom VVX support page and grab a copy of the lovingly entitled: “Deploying Polycom® UC Software for use with Microsoft® Lync™ Server”.

An important recommendation that I can give you is to always test your configuration files on a real phone before deploying them into the wild, because subtle errors can cause things not to work as desired.

The Wrap Up

Well, that's it, my first version 2.0 script! Enjoy, and let me know if you have any issues, feedback or have any enhancement requests.
