Important Notices

  • You must upgrade to VidyoGateway™ beta version 4.2 from VidyoGateway version 3.5.2. Therefore, if you have a VidyoGateway version earlier than 3.5.2, you must first upgrade to 3.5.2 and then upgrade to beta version 4.2.
  • Please refer to the “Upgrade Steps” section below to upgrade from VidyoGateway 3.5.2 to version 4.2. These steps must be done in order.   
  • There are functional changes between VidyoGateway version 3.5.2 and 4.2. Please review the “Notable Changes” section below in detail before upgrading if you have installed a previous VdiyoGateway version 4.2 Beta. 
  • Important Note: If you have installed a previous VidyoGateway version 4.2 beta, you should first downgrade your VidyoGateway to 3.5.2 using the Recovery Utility on the System Console, and then upgrade directly to the GA 4.2 version. For more information, please refer to "Running the Recovery Utility" in the Performing Advanced Configuration section of the VidyoGateway Admin Guide.  



  • VidyoGateway version 4.2 is compatible with VidyoPortal version 18.3.1 or later.

Do not install on a version earlier than the version listed in the preceding table. Also, if you upgrade to VidyoGateway 4.2, you do not need to install Security Update (SU20) or Security Update 21 (SU21). SU20 and SU21 are already included as part of the upgrade package.


Upgrade Steps

To upgrade a 3.5.2 cluster, please perform the following steps in order.


  1. Place all Cluster Nodes into Maintenance mode.
  2. Upgrade all the Cluster Nodes.
  3. When the Cluster Node upgrades are completed and back online, then upgrade the current Standby Controller.
  4. When the Standby Controller upgrade is complete, proceed to upgrade the Active Controller.

    The previous Standby Controller will now become the 4.2 Active Controller.
  5. When the former 3.5.2 Active Controller completes its upgrade, it will then become the 4.2 Standby Controller.

    If you do not perform the above steps in order; there will be cluster instability and/or configuration loss.


Notable Changes

The following list includes notable changes in VidyoGateway version 4.2:

  • SIP Protocols
    • Previously, SIP protocol support could be configured per direction (Inbound or Outbound). In VidyoGateway version 4.2, this configuration is bi-directional. For example, if the UDP protocol is enabled or disabled, it is automatically enabled or disabled for both directions. The VidyoGateway Web Admin has been updated to reflect this.
  • H.323 Support
    • Support for H.323 latching is no longer supported in VidyoGateway 4.2 or later.
    • H.323 Gatekeeper registration is no longer supported. Only H.323 Neighboring is supported (in both clustered and standalone mode).
  • Audio
    • Disabling AGC and configuring the AGC Target Level is no longer supported. The VidyoGateway now automatically enables this function.
  • Video
    • The Video Loopback option is no longer supported and has been removed from the VidyoGateway Admin web interface.
  • Prompts
    • There is now a new prompt available for configuring a Welcome Message for audio-only participants.
  • Media Ports
    • The minimum port number for media traffic must now be a number between 2001 and 65535. The recommended value is 2001. Therefore, the Media Min UDP Port has changed from 1 to 2001. This update will automatically occur upon upgrade.
  • Display Option in CDR
    • Previously the administrator could configure how the display name would be logged in the CDR (E.164 format or Display Name). In VidyoGateway 4.2 – if a legacy endpoint has an E.164 number configured, then this will automatically be set in the CDR.
  • Auto Disconnect of Last Participant
    • In VidyoGateway 4.2, the Last Participant Timer has been replaced by two options:
      • Maximum Call Duration: This option specifies the maximum length of a VidyoGateway call. This value defaults to 720 minutes (12 hours). This can be increased or decreased as needed.
      • Auto Disconnect Last Participant: In order to be more efficient at resource management, if there is only one VidyoGateway participant left in the conference, then this user will be automatically disconnected. This option can be turned off by an administrator ifs desired.
  • Resource Reservation
    • Selecting between Static and Dynamic is no longer supported. The VidyoGateway will dynamically accept or reject calls based on current CPU configuration and utilization. To determine the capacity of your VidyoGateway, refer to the VidyoGateway Admin Guide.
  • Access Control
    • The option to “Automatically block IP addresses with Whitelist and Blacklist overrides” is no longer available. All other existing modes are supported.
  • Service Configuration
    • The “Enable Crop” option is no longer supported.
    • The “Send DTMF Signaling” option is no longer available. DTMF Signaling is now always enabled for endpoints that support it per RFC 4733/2833 for SIP and via signaling for H.323.
  • IVR 
    • The default IVR recordings have been changed. If you prefer to use the existing VidyoGateway version 3.5.2 recordings, you may download them and upload them after upgrading to VidyoGateway version 4.2. Note: If you have replaced the default IVR recordings with your own version, these will be preserved after upgrade.
    • The “Jump to IVR if wrong extension is entered” option is no longer available to turn off. This behavior is always enabled.
    • The "Call Disconnecting" IVR prompt is no longer available.

Key Summary
VGW-2566 When a Safari® browser is used to export whitelisted and blacklisted IP addresses, the export may fail.
