VidyoGateway: About Version 20.2.0

What's New in This Release

• Video Mute Options via DTMF
  
  • Users joining a call with video can now use DTMF control keys to mute and unmute their video and/or audio. Prior to this release, only audio-only users joining a call could use DTMF control keys to mute and unmute their audio.
  • Admins can enable and disable this feature using the "Enable video control keys" checkbox on the General > Prompts page of the VidyoGateway Admin portal. 
    • You can also use this page to change the welcome message that video users will see when joining a call, select how long in seconds you want the messages to display, and select how opaque the messages will appear on the screen.
      
      
      
      
  • To learn more, refer to the "Configuring Prompts and Call Control via DTMF Tones" section of version 20.2.0 of the VidyoGateway Administrator Guide.
• Ability to Enable and Disable Avatars
  
  • You now have the ability to enable or disable the avatar that displays when a participant has their video  source muted (that is, when that participant is in audio-only mode).
    • When enabled, if a participant’s video source is muted during a call, an avatar with the first three letters of their name appears on their tile.
    • When disabled, if a participant’s video source is muted during a call, their video tile does not display at all.
  • Easily configure this setting using the new "Use Avatar" checkbox on the General > Advanced page of the VidyoGateway Admin portal. 
    
    
    
    
  • To learn more, refer to the "Configuring Advanced Settings" section of version 20.2.0 of the VidyoGateway Administrator Guide.
• Updates for Experimental Features
  • The Experimental Features section of the VidyoGateway Admin portal General > Advanced page allows you to send API requests to the VidyoGateway (after you’ve authenticated using an API key).
    • These API requests can now be sent via https. Prior to this release, only http was supported.
  • You can also use Experimental Features to enable RTMP streaming via API.
    • Starting with version 20.2.0, you can use RTMPS when establishing a stream via the VidyoGateway. To do so, simply enter “rtmps” in the stream destination. 
      
      
  • To learn more, refer to the Using VidyoGateway Experimental Features article on the Vidyo Help Center. 
• Audio Quality Improvements
  • For even better-quality audio, the audio sample rate for and RTMP streaming is automatically negotiated at 48 kHz instead of 16 kHz.

Notable Changes

The following list includes notable changes for VidyoGateway versions 4.2, 4.2.1, and 20.1.0: 

• SIP Protocols
  • Previously, SIP protocol support could be configured per direction (Inbound or Outbound). In VidyoGateway version 4.2 and later, 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 3001 and 65535. The recommended value is 3001. Therefore, the Media Min UDP Port has changed from 1 to 3001. 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 and later – 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 and later, 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 and later. 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.

Known Issues

---

 

The following table lists the issues that still remain, but you can be sure our teams are working hard to fix them:

VidyoGateway - Known Issues
Key	Summary
XGW-754	The "You are the only person in the call" prompt cannot currently be modified.
XGW-574	If a user has duplicate entries in their CA file, calls to legacy endpoints do not connect successfully.
XGW-573	H.323 calls that go through the gatekeeper do not show the EndpointPublicIPAddress correctly in the CDR.
XGW-547	When an H.323 call is dialed out to a legacy device via a saved Legacy Endpoint Alias, the IP address of the device is displayed in the call rather than the device's alias.
XGW-539	If a user adds a service prefix on the "Add Service" pop-up on the VidyoGateway Admin UI Services tab and then clicks Save, the VidyoGateway sometimes reboots.
XGW-498	When participants first dial into a video conference, audio-only participants are audible to other participants during the welcome message and DTMF instructions (e.g., enable disable entry/exit and mute/unmute audio). The audio-only participant does not hear the other participants during this time (there is only one-way audio) and will only start to hear other participants when the instructions have fully played.
XGW-402	If audio-only participants join a call where all users are hard-muted, the audio-only participants are not muted but the UI on the portal moderation page shows them as muted. Workaround: Confirm trusted CA bundle does not have duplicate entries. Once confirmed, re-upload trusted CA bundle.
