Oct 7, 2011 Question: What SIP or UC Software Version or BootROM/Updater Version is supported by my Phone?

Resolution: Please check => here <=

VVX phones, Poly Trio 8800, 8500 and 8300, CCX 500, CCX600 , CCX700 or CCX 400 (only 6.2.11 or later):

The above phones simply either download the combined or split files if available.

Note: There is no requirement for these phones to download an Updater/Upgrader/BootROM/Downgrader!

Older phone model additional considerations:

The downloaded software usually comes in two different variants:

• Combined download should be used where phones may be running pre-4.0 BootROM. 
  NOTE: Please bear in mind that the combined file is large and may cause long downloading times for the individual phones
  
  
• Split download file is recommended, but requires that all phones are running BootROM 4.0 or newer.
  Note: The split file may be a better option on slow network connections

May 14, 2012 Question: Can I support a mix of legacy SIP and UCS Phones on the same Provisioning Server?
Resolution: Please check => here <=

Checking the current Software Version:

Oct 7, 2011 Question: How can I find out my SIP UC Software Version or the BootROM Version of my Phone?
Resolution: Please check => here <=

SOFTWARE UPGRADE PATH

Updating to SIP 3.1.x:

If the phone is running an older version of Software you will need to download the compatible SIP Version and in addition the BootROM.

Note: The accompanying sip.cfg and phone1.cfg must be used

Oct 7, 2011 Question: What is the relevance of the sip.cfg and phone1.cfg files?

Resolution: Please check => here <=

Updating to SIP 3.2.x:

If the phone is running an older version of Software you will need to download the compatible SIP Version and in addition the BootROM.

Note: The accompanying sip.cfg and phone1.cfg must be used

Oct 7, 2011 Question: What is the relevance of the sip.cfg and phone1.cfg files?

Resolution: Please check => here <=

Updating to UCS 3.3.x:

If the phone is running an older version of Software you will need to download the compatible UCS Version and in addition the BootROM.

Note: Do not use any old sip.cfg or phone1.cfg and utilize the cfcUtility to convert your old configuration files instead

Oct 03, 2012 Question: What is the cfcUtility and where can I get it?

Resolution: Please check => here <=

Updating to UCS 4.x.x:

NOTE: Aug 10, 2016, the Polycom SoundPoint Series IP321, IP331, IP335, IP450, IP550, IP560, IP650 and IP670 end of life.
We no longer host the BootROM Upgrader Software!

If the phone is running an older version of Software you will need to download the compatible UCS Version and in addition the BootROM 4.4.0 B Upgrader.

As an example download software version UCS 4.0.14 (or later) and BootROM 4.4.0 B Upgrader and unzip the content of both of the downloads into one directory.

• Older software for example for a SoundPoint IP >here<

You will then have to point the relevant Server (HTTP(s), FTP(s) or TFTP to the directory where the Software has been unzipped.

Before you can successfully install UC Software 4.x.x onto phones running Polycom® UCS released prior to version 4.0.0, you must perform a required upgrade procedure using the Polycom® Upgrader 4.0.0 Utility.

Before you download and install Polycom® UC Software version 4.0.x or higher, Polycom strongly recommends that you review the changes to the upgrade procedures detailed in the Polycom® UC Software 4.0.5 Administrators’ Guide or newer and Engineering Advisory 64731 Polycom® UC Software 4.0.0: Upgrade and Downgrade Methods.

Note: A SoundStation IP 6000 and IP 7000 need the Updater upgraded as shown => here <=.

Downgrading from UCS 4.x.x:

NOTE: Aug 10, 2016, the Polycom SoundPoint Series IP321, IP331, IP335, IP450, IP550, IP560, IP650 and IP670 end of life.
We no longer host the BootROM Downgrader Software!

If the phone is running the new version of UC Software you will need to download the compatible Downgrader (Example Polycom UC Downgrader 4.5.0B Utility) 

This will downgrade the compatible phones to UCS 3.3.2 and you then can update to any other UCS 3.3.x Version or Downgrade to SIP 3.2.x

Please check the Polycom UC Software 4.0.x Upgrade and Downgrade Methods (Engineering Advisory 64731).

SoundStation IP6000 and SoundStation IP7000 Examples:

Basically the process is the same as described in this FAQ but you need to ensure you also have the relevant compatible Updater:

First download:

• Polycom UC software 4.0.14 for SoundPoint IP, SoundStation IP, VVX 500, 1500 Business media Phones a...

• SoundPoint IP, SoundStation IP and Polycom VVX Upgrader 4.4.0 Rev B
• Polycom Updater 5.0.14 for SoundStation IP 6000 and 7000 Phones

Unzip all of the above into one directory and then point the phone to the Server

Automation

Local provisioning automated DHCP Server Options:

Poly Phones delivered from the Factory are preconfigured to be using DHCP Custom Option 160 or 161 (If ordered as Skype for Business SKU)  and then Option 66 to inform themselves about the location of a potential Provisioning Server.

Adding a Custom 160 / 161:

 

 

 

And then select the actual new Option 160 or 161

 

Option 66: 

Above Example uses the Standard Provisioning Factory Default Username of PlcmSpIp and the Password PlcmSpIp and would utilize these using FTP as the protocol and 10.252.149.100 as the Server IP or Hostname.

This is submitted via a DHCP String and could be in one of the following formats:

HTTP(S), FTP(S) or TFTP.

Example DHCP string: 

ftp://Username:Password@IP_Address or URL

A Username & Password could also be:

http://domain\username:password@IP_Address_or_URL

NOTE: If the password as an example contains an @ please replace this with correct ASCII Encoding for the character in this case %40 .

Example:

ftp://Username:%40123$@IP_Address or URL

The above would use @123$ as the password or the phone would interpret the @Symbol as the separator between the password and the IP Address or URL.

If a Poly Phone is used in a non-supported Environment the End Customer is responsible for setting up a local Provisioning Server.

Additional filtering can utilise the DHCP Vendor Option 60 as explained => here <=

Poly Logs:

013527.204|dhcpc|3|00|dhcListener: Read succeeds: eth0 option: o-161 ftp://t590d:1@10.252.149.100

Setting the DHCP logging level as Settings > Logging > Module Log Level Limits > DHCP Client > Event 3 will show the received Option in the logs

Pointing a Phone to an Provisioning Server manually:

NOTE: Please remember that you may need to require to add a local Firewall Rule or Disable the Firewall completely !

To manually point the Phone to a Provisioning Server please do the following Steps:

Reboot the Phone (unplug Ethernet cable and plug back in)

• Press Setup or Cancel and then Setup when the countdown is being displayed
   
• Use the standard => Password <= of 456
  
  
• Select Provisioning Server
  
  
• Select DHCP Menu and press select/enter
  
• Change the Boot Server to static via the Edit Button
  
• Press Exit
• Scroll down to Server Type / Server Address etc. and press select/enter and change to the following values
  

Server Type:	FTP(s), TFTP or HTTP(S)
Server Address:	IP Address or Hostname of your Server
Server User:	Username of your server (if needed)
Server Password:	Password of your server (if needed)

• Exit and Save and let the Phone re-boot.

In a normal setup we recommend using an FTP Server in order to provision the Phone and in addition to allow the Phone to upload its own <mac>-app.log and <mac>-boot.log files.

The Server directory should contain the unzipped Version of either UCS or SIP Software (depending on the compatible version)

NOTE: check => here <= if legacy phones are used

The FTP Server needs to allow append and write for this functionality.

Above is vital for Polycom Support in order to troubleshoot cases.

The Customer needs to create their own individual Configuration Files and can use separate files for a Phones registration (per Phone Mac Address) and Global Settings like SIP Server, NTP and Language etc.

When is a Provisioning Server needed:
 

• Running an older Software than UCS 3.3.0 as the phone needs to load the sip.cfg / phone1.cfg
  
  
• Upgrading a Phone from an older Software to UCS 4.x.x
  
  
• Language change from English on pre UCS3.3.x Software Versions (example SIP 3.2.7 or older)
  
  
• License provisioning for H323, Corporate Directory / LDAP, Local / Centralized Conferencing and Audio Recording
• Central Phone Book via 000000000000-directory.xml or individual <mac>-directory.xml
  
  
• Log Files for Support troubleshooting prior to UCS 4.0.0
  
  
• Specific Customer configurations parameters that cannot be changed via the Web Interface (UCS 3.3.0 introduced a large scope of changes and the new UCS 4.0.0 has enhanced this functionality even more) require the usage of configuration files being loaded from the provisioning server.

Example FTP Server using current phones:

• Download the latest Phone Software from => here <=
  
  
• Create a directory and unzip the archive into this directory (Example C:\Users\Username\Provisioning\UCS_6.3.0.14929_ITS146_Rel )
  
  
  
  
• After downloading and installing the Server from => here <= a User needs to be set up to be utilized
  
  
• Create a new user.
  If this is for a single Upgrade the username can be PlcmSpIp and the password PlcmSpIp as this is the factory default of the phone
  
  
  
• Point the new user to the Directory previously unzipped the above archive
  
• Ensure the Files right boxes are all ticked
  
• Once the phone is pointed at the FTP Server address the Phone will attempt to download the relevant files
  
  

Example FTP Server using legacy phones:

Note: Below example utilizes the Freeware FTP Server Filezilla. Please ensure to set up the correct Firewall settings and liaise directly with Filezilla for any issues encountered with their Software. The example provided is utilizing UCS 4.1.0 Rev B as the Polycom Phone Software

NOTE: Above UC Software 4.1.0 is just an example and is for LYNC deployments only. For SIP please check the Support page for the compatible software!

Pre-requisite:

• Download the latest Phone Software from => here <=
  
  Example UCS 4.1.0 Rev B (!! please check that your phone is compatible as shown => here <= !!)
  
  
  !! Both files are required as outlined above !!
  
  
• Create a directory and copy the two archives into this directory (Example D:\Software\UCS410revB\ )
  
  
  
  
• Unzip the two Archives so they are in the UCS410revB Directory
  
  
  
  

Setting up the server

• After downloading and installing the Server from => here <= a User needs to be setup to be utilized
  
  
  
  
• Create the new user 410b
  
  
  
  
  
  
  
• Add the directory created for above Software to the new User
  
  
  
  
• Ensure that the User 410b is able to append and write/delete files
  
  
  
  
• Once the phone is pointed at the FTP Server address the Phone will attempt to download the relevant files

Setting up Microsoft IIS for HTTP Provisioning

NOTE: Please be aware that Polycom does not provide any support on the below and any changes or permissions are at your own risk !!

A "normal" IIS server is unable to append using HTTP or HTTPS. Utilising HTTPd, Apache or any other flavor of HTTP/HTTPS servers should work.

The LOG_FILE_DIRECTORY="" can be used to define a FTP server instead. Example:

• LOG_FILE_DIRECTORY="ftp://username:password@domain"

Below information is based on a Microsoft Windows Server 2008 R2 and assumes that you install the below on a separate server that is part of an existing domain.

Option 1 Basic Authentication:

• Enable the Web Server (IIS) via adding a new Role

• You may skip the next page if shown

• Select the Web Server (IIS) and click on Install

• Select in addition the WebDav Publishing

• Scroll further down to add Basic Authentication (Note: in a follow up further below XXX will be added !)

• Click Next and then Install to complete this step to install IIS

Once IIS is installed please download and unzip the Software you wish to provision into the C:\inetpub\wwwroot Directory

Example:

• Launch the IIS services manager under Administrative Tools

• Expand the default Web Site and select the Mime Types

• A list of Mime Types the web server supports are listed and you will require to add an additional minimum 3 mime types to recognize Polycom specific file extensions.
  (NOTE: please check => here <= for all required types !)

  

• Select Authentication

• Enable Basic Authentication and Disable Anonymous Authentication

• Click on Edit and add the default Domain so the phone just requires the Username PlcmSpIp and Password PlcmSpIp

• Select Directory Browsing

• And enable the following

NOTE: As a standard Windows will not allow basic passwords so the following is at your own risk!

In order to enable a basic Password like the Polycom factory default of PlcmSpIp you will need to change the Password Policy

• On your Active Directory Server start a Console via MMC and Add/Remove a Snap-in via the File Option

• Select the Group Policy Management Editor and add this and press OK

• Browse for the Group Policy Object

• Select your Default Domain Policy and proceed

• Select Computer Configuration => Windows Settings => Security Settings => Account Policies => Password Policy and Disable the setting.

NOTE: The above is only an example to create a User that can utilize the Standard Polycom Password PlcmSpIp and may violate local policies !

• Using Active Directory Users and Computers, create a new user. You will be assigning this user to your WebDAV authoring in a later step.

• Create the PlcmSpIp Provisioning user account. This can be whatever user account you want to use. The default is PlcmSpIp and passwordPlcmSpIp.

• Select the WebDAV authoring rules to provide write permission to your provisioning directory

 

• Enable WebDav

• Add an Authoring Rule

• Specify the PlcmSpIp user and give Permission to Read and Write

• Right click on the Default Web Site and select Edit Permissions

• Edit the Security

• Add a new User

• Add the newly created PlcmSpIp User and Check Names and then click on OK

• Allow Full Control for the PlcmSpIp user and press Apply and then OK

• Select the PlcmSpIp User and select Advanced

• Change Permission for the PlcmSpIp user

• Uncheck the “Include inheritable permissions from this object’s parent” (confirm the follow up warning via Add )

• Check the “Replace all child object permissions with inheritable permissions from this object” option

• Apply the settings and confirm the process by clicking YES on the next pop up Box and return to the previous menu via OK.
  
  
• Leave the next Menu via clicking OK and OK.

NOTE: IIS or the Server hosting IIS may need to be restarted after a successful installation !

The Option 160 or 66 DHCP Server string explained => here <= would now be as follows:

http://PlcmSpIp : PlcmSpIp @ 10.252.122.133/UCS_5.2.0.8330_rts55rel

Setting up Microsoft IIS for HTTPS Provisioning

NOTE: Please be aware that Poly does not provide any support on the below and any changes or permissions are at your own risk !!

The below information is based on a Microsoft Windows Server 2012 and assumes that you install the below on a separate server that is part of an existing domain.

CCX, VVX and Trio UC Software 5.9.0 or later have an overview of the built-in certificates and this  can be found via the Web Interface:

• Settings > Network > TLS > SSL Certificates
  
  

Using one of these certificates authorities enables a user to use a certificate on the server without the need to install one on the phone so the phone can trust the server.

This Guide also assumes that you have set up an AD User called ftpuser with a password of T3ch!ab and the C:\inetpub\wwwroot Directory in the sbaierhome.lab domain.

The above HTTP Instructions already document how to add IIS as a role and the relevant addition of Basic Authentication, Mime Types and WebDav

The C:\inetpub\wwwroot Directory directory is being used for HTTP so we create a new directory called C:\inetpub\wwwhttps

• • Launch the IIS services manager under Administrative Tools and create a new Site (HTTPS Web Site)
     
    (We remove the HTTP and add HTTPS via binding later)
    
    
  • Create a Server Certificate via "Create Domain Certificate"
    
    Note: If you already have a certificate signed by a Poly trusted authority this step is not required. Please work with your network admin Team
    
    
    
    
    
  • Add the Distinguished Name Properties
    
    Note: The Common Name is the name of this server that is verified
    
    
    
  • Select your Online Certificate Authority via clicking on Select
    
    Note: This is usually your AD Server. For more details work with your Network Team
    
    
    
  • Give the Certificate itself a name so you can identify it easily
    
    
    
    
  • Finish the process and the newly created and signed certificate can be checked via double-clicking on the certificate
    
    
    
    
  • Select the Certification Path tab and View Certificate
    
    
    
    
    
  • Click on Next in the "Welcome to the Certificate Export Wizard"
    
    
    
    
  • Select Base-64 .CER and select Next
    
    
    
    
  • Provide a name for the exported Certificate
    
    
    Example ExportedRootCertificateForPhoneProvisioning.cer
    
    
    Store the newly created Certificate on a location that allows you to retrieve it. For this exercise we call it ExportedRootCertificateForPhoneProvisioning.cer
    
    
  • Browse to the new HTTPS Web Site and select Bindings
    
    
    
    
  • Select Add
    Note: you will see the original binding for port 80 which we can now remove after assigning HTTPS
    
    
    
    
    
    
  • Select SSL Settings
    
    
    
    
    
  • Set Require SSL and Ignore Client Certificates
    
    
    
    
  • Right Click on the HTTPS Website and select Manage Website
    
    
    
    Ensure the Physical Path points to the inetpub\wwwhttps Directory
    
    
    
  • Select Physical Path Credentials
    
    
    
    
  • Path Credentials
    
    
    
    
    
    
  • Select Authentication
    
    
    
    Ensure you Disable Anonymous Authentication and Enable Basic Authentication
    
    
    
    
  • Change the WebDAV Authoring
    
    
    
    Enable
    
    
    
    Add / Edit the Authoring Rule
    
    
    
    
  • Open the Windows Explorer and Navigate to the wwwhttps Sub Directory and right-click to change/add the user
    
    
    
    
    Add the User and set the Permissions
    Note: Please check with your network admin on any local policies.
    
    

Once all of the above has been set you should be able to browse to the URL of the Provisioning Server and receive a challenge for a Username and Password.

Copy the ExportedRootCertificateForPhoneProvisioning.cer to your main PC so you can create the certificate for the Poly phone to use.

NOTE: Using the above phone built-in certificates does not require the following step!

In order for the Phone to be able to either import this via the Web Interface or load it from a Provisioning server, the file needs to be correctly formatted.

NOTE: It should be a DER-encoded certificate in PEM format. PEM certificates usually have extension such as .pem, .crt, .cer, and .key. They are Base64 encoded ASCII files and contain "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----" statements.

device.set="1" 
device.sec.TLS.customCaCert1.set="1" 
device.sec.TLS.customCaCert1=" place certificate here " 

The Certificate can then be seen:

Poly phones also support FTP over TLS provisioning

In the below example we use FileZilla server from >here<

NOTE: Please be aware that Poly does not provide any support on the below and any changes or permissions are at your own risk!!

CCX, VVX and Trio UC Software 5.9.0 or later have an overview of the built-in certificates and this  can be found via the Web Interface:

• Settings > Network > TLS > SSL Certificates
  
  

Using one of these certificates authorities enables a user to use a certificate on the server without the need to install one on the phone so the phone can trust the server.

Creating a Server certificate

In the below example we are using the FileZilla Server built-in facility to create a certificate. The common name needs to be the FQDN of the Server where a DNS A record has been set up pointing to the IP address of the PC running Filezilla.

• Open Filezilla Server via Edit > Settings
  
  
  
  
• Select FTP over TLS settings
  
  
  
  
• Ensure to disable "Require TLS session resumption on data connection when using Proto P"
  
  
• Select "Generate a new certificate"
  
  
  The above steps and the follow up are only needed if you do not already have a valid certificate from a authority the phone trusts
  
  
• Fill in the fields and ensure the DNS record is set up for the Common Name
  
  
  
  
• It should be a DER-encoded certificate in PEM format. PEM certificates usually have extension such as .pem, .crt, .cer, and .key. They are Base64 encoded ASCII files and contain "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----" statements.
  
  
• The Save Key and certificate ensures the .crt file is stored somewhere so we can open and edit this to create the certificate we want to import on the phone. Open the CRT file and copy the Begin Certificate section until end certificate
  
  
  and create a XML conform CFG file with the certificate
  
  
  
  
• Import the newly created file into the phone using the Web Interface Utilities > Import & Export Configuration > Import Configuration
  
  
• Verify the certificate is imported
  
  
  
  
• Enter the provisioning server credentials and/or use DHCP option 160/161/66 from >here<

The message "SSL certificate verify result: certificate is not yet valid (9), continuing anyway" appears as we do not have a valid NTP server
