Release Notes for Voice and Video Firmware 8.7 for Cisco Virtualization Experience Client 6215

Introduction

Cisco Virtualization Experience Client 6215 requires the Cisco Voice and Video Firmware add on to work with Cisco UC Integration for Microsoft Lync 8.6 or later, or Cisco Unified Personal Communicator Release 8.6 or later. The Citrix receiver, which opens in the Mozilla Firefox web browser, provides the connection to the hosted virtual desktop (HVD). Data, such as configuration and logging, travels over this virtual channel, which is contained within the ICA connection. All audio and video streams travel directly from a thin client to another thin client or a telephone, without going through the HVD.

For more information, see the Release Notes for the following products:

Cisco UC Integration for Microsoft Lync

Cisco Unified Personal Communicator

These release notes are updated for every maintenance release but not for patches or hot fixes. Before you install Cisco Voice and Video Firmware for Cisco Virtualization Experience Client 6215, we recommend that you review this document for information about issues that may affect your system.

This release provides the following new functionality and enhancements:

  • Cisco UC Integration for Microsoft Lync Release 8.6(1) users can choose to control a desk phone.
  • Cisco Unified Personal Communicator Release 8.6(3) users can choose to control a desk phone.
  • Cisco Unified Communications Manager 9.0. is supported.
  • Cisco Unified Presence 9.0 is supported.

Installation Notes

The high-level installation steps are as follows:

  • On the HVD, configure the registry settings for the virtual environment.
  • On the HVD, install Microsoft Office Communicator or Microsoft Lync and Cisco UC Integration for Microsoft Lync, OR install Cisco Unified Personal Communicator.

    Note


    Do not install Cisco UC Integration for Microsoft Lync and Cisco Unified Personal Communicator on the same HVD.


  • On the thin client, install the Voice and Video Firmware add on for Cisco Virtualization Experience Client 6215.

    Note


    All software downloads include a Checksum folder, which contains SHA-1 checksums that you can use for verification.


  • If your network does not permit access to the Internet, set up the documentation for the end users.
  • On the Cisco Unified Communications Manager, create the Cisco Virtualization Experience Client 6215 (VXC 6215) devices for the users.

For step-by-step installation instructions, see the Deployment Guide for Cisco Voice and Video Firmware.

Limitations and Restrictions

Telephone Selection

With this release of the Voice and Video Firmware, Cisco UC Integration for Microsoft Lync Release 8.6.1 and Cisco Unified Personal Communicator Release 8.6.3 users in the virtual environment can choose another telephone (for example, a Cisco IP Phone) to control. This feature is not available with earlier releases of Cisco UC Integration for Microsoft Lync and Cisco Unified Personal Communicator.

Multiple Virtualization Experience Client 6215 Devices

Create only one Virtualization Experience Client 6215 (VXC 6215) device for each user. If multiple Virtualization Experience Client 6215 (VXC 6215) devices exist for a user, the first device registers, but Cisco UC Integration for Microsoft Lync or Cisco Unified Personal Communicator does not control the device.

Multiple Hosted Virtual Desktops for a User

If you create and assign multiple hosted virtual desktops (HVD) for users, ensure that they sign into only one HVD at a time. Multiple HVD accounts could result in a user signing in from different devices, leading to multiple registrations with the Cisco Unified Communications Manager. Multiple registrations are not supported.

Computer Telephony Integration

The following Cisco UC Integration for Microsoft Lync or Cisco Unified Personal Communicator features are available on the Call Strip:

  • Add to or remove video from a call.
  • Toggle video pause for a call.
  • Toggle mute for audio.
  • Adjust volume control.

In the event of a connection failure between the thin client and the hosted virtual desktop (HVD), the Citrix receiver closes and the Call Strip and Video window (for a video call) appear on the thin client desktop. If the user is on an active call at the time of the failure, they can finish the call and end it from the Call Strip. If the user ends the call from the Call Strip, all calls on hold end. If the user signs back in to the HVD before ending the active call, they can resume the held calls. If the connection failure occurs with no active call, all held calls disconnect.

Users can choose whether to send or receive video for calls. This setting is located on the Cisco UC Options > Video tab and applies to all calls that the user makes or receives.

With Cisco Virtualization Experience Client 6215 and the Voice and Video Firmware add on, virtual installations of Cisco UC Integration for Microsoft Lync or Cisco Unified Personal Communicator

  • Start in Cisco Virtualization Experience Client 6215 mode. Users cannot change the mode.
  • Autoselect the Cisco Virtualization Experience Client 6215 device to control. Each user should have only one Cisco Virtualization Experience Client 6215 device.

Users can manage cameras and audio devices by using the Device Selector. The Device Selector icon appears in the notification area.

The volume control for Cisco UC Integration for Microsoft Lync or Cisco Unified Personal Communicator is on the Call Strip.

Video resolution is fixed. Users cannot resize, minimize, or expand the Video window to full screen. Users can move the Video window freely around the desktop; it always appears on top (but not on top of the Call Strip).

Video Conference Support

For Video Conference Servers, the highest supported video level is H.264 level 1.2.

Echo Cancellation

Echo cancellation is enabled only for audio calls.

Cameras and Other Applications

To support use of the camera by other applications, such as Skype and Adobe Connect, Citrix 5.5 is required. With Citrix 4.0 or 5.0, only Cisco Virtualization Experience Client 6215 can use the camera.

Camera Hot Swap

Ideally, users should not unplug the camera during a call unless they first place the call on hold, or use the Call Strip to pause sending video. If a user tries to switch cameras during an active call, they cannot send video for that call or for any subsequent calls.

To resolve this issue, have the user:

  1. Click to stop sending video for the call.
  2. Plug the same camera back into the same USB port.
  3. Click to start sending video for the call again.
  4. Switch the camera when they do not have an active call in progress.

Request to Add Video

The behavior of this feature in a virtual environment is slightly different than in a non-virtual environment. Users can receive a Request to Add Video at any time after they answer a call. If the following conditions are true, a Cisco Virtualization Experience Client 6215 user receives a Request to Add Video, immediately after answering the call:

  • The video preference of the Cisco Virtualization Experience Client 6215 user is set to Audio-only. The default setting is Send and receive video.
  • The Cisco Virtualization Experience Client 6215 user places a call to a non-virtual Cisco UC Integration for Microsoft Lync user.
  • The non-virtual Cisco UC Integration for Microsoft Lync user accepts the call by clicking Answer with Video.

The caller can choose whether to accept the Request to Add Video.

911 Notice IMPORTANT NOTICE PLEASE READ

During an emergency, soft phone technology may not provide the most timely or accurate location data if used for a 911 emergency call. Calls may be misdirected to the wrong emergency response center or the emergency response center may make errors when determining your location. USE A SOFTPHONE ONLY AT YOUR OWN RISK DURING AN EMERGENCY. Cisco will not be liable for resulting errors or delays.
