Introduction

Cisco Virtualization Experience Client 6215 requires the Cisco Voice and Video Firmware 8.6 add on to work with Cisco UC Integration for Microsoft Lync 8.6 or Cisco Unified Personal Communicator 8.6. 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:

http://www.cisco.com/en/US/docs/voice_ip_comm/cucimoc/8_5/english/release/cucimocReleaseNote.html

Cisco Unified Personal Communicator:

Telephone selection

With Cisco UC Integration for Microsoft Lync Release 8.6, users in the virtual environment cannot choose another telephone to control. With Cisco UC Integration for Microsoft Lync Release 8.6.1, users in the virtual environment can choose another telephone (for example, a Cisco IP Phone) to control.

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 HVDs 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 8.6 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. Only the Cisco Virtualization Experience Client 6215 device works with Cisco Virtualization Experience Client 6215; users cannot select a different 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.

Shared Lines

In a HVD deployment, Cisco Unified Personal Communicator or Cisco UC Integration for Microsoft Lync can share the line appearance with other devices. All endpoints, which are not set to DND Call Reject, receive an alert for all incoming calls and the caller hears the ring tone.

A Cisco Virtualization Experience Client user's availability status appears on Cisco Unified Personal Communicator or Cisco UC Integration for Microsoft Lync, and on other devices that share the line appearance.

Cisco Virtualization Experience Client users with Shared Lines can

put calls on hold

forward active calls

transfer active calls

Cisco Virtualization Experience Client users cannot use Cisco Unified Personal Communicator or Cisco UC Integration for Microsoft Lync to resume a call placed on hold from another Shared Line endpoint.

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.

Important notes

Call Strip does not appear correctly

Conversation window does not close after call ends

Registration issue with new Cisco Unified Communications Manager

Cisco Virtualization Experience Client 6215 copyright

Copyright © 2012 Cisco or its affiliated entities. All Rights Reserved.

Call Strip does not appear correctly

If the screen resolution setting does not match the aspect ratio of the physical display, the call strip may appear outside, or too far inside, of the display area. This issue occurs only during the first session after a reboot of the thin client. To resolve the issue, change the screen resolution setting to Auto-detect.

Conversation window does not close after call ends

If the connection to the Cisco Unified Communications Manager fails while a user is on a call, the call continues. However, after the user ends the call by clicking the End Call button, the Cisco UC Conversation window remains open. To close the Cisco UC Conversation window, the user must click the End Call button on the Cisco UC Conversation window.


Note Without a connect to the Cisco Unified Communications Manager, the End Call button on the Cisco UC Conversation window cannot end the call. After a connection failure, users must end the call by clicking the End Call button on the Call Strip.


Registration issue with new Cisco Unified Communications Manager

After you move a user from one Cisco Unified Communications Manager to another, the user cannot successfully register with the new Cisco Unified Communications Manager. This issue occurs because the client tries to register with the certificate for the original Cisco Unified Communications Manager.

To resolve this issue, delete or rename the vxcc.bin file, and then have the user restart Cisco UC Integration for Microsoft Lync. The vxcc.bin file is located in the following directory on the hosted virtual desktop (HVD):

<USER>\AppData\Local\Cisco\Unified Communications\Virtualization\


Note The AppData folder is hidden; you must set Windows Explorer to view hidden files.

Troubleshooting

Problem Reporting Tool

Log files and core dumps

Audio issues

Get the version of Cisco Virtualization Experience Client 6215 installed on the thin client

Ensure that vxcc is running on the thin client

Ensure that credentials are passed down the virtual channel to the thin client

Ensure that the registry key values are correct

Ensure that the Cisco HVD Agent is started

Problem Reporting Tool

The Problem Reporting Tool (PRT) is a small program, which automatically runs in the event of an unrecoverable error, unhandled exception, or crash in Cisco UC Integration for Microsoft Lync or Cisco Unified Personal Communicator.

If a user experiences an error which does not crash the software, they can run the PRT themselves from the Microsoft Office Communicator or Microsoft Lync menu; Tools > Create Problem Report. Users can run the PRT from the Cisco Unified Personal Communicator menu: Help > Create Problem Report.


Note Users must accept the privacy agreement to run the PRT.


The tool creates a problem report, which is a zip file that you can send to the Cisco Technical Assistance Center (TAC), to provide the necessary information to solve the problem. The tool saves the file to the user's desktop.

We recommend that users set the level of logging to verbose for Cisco UC Integration for Microsoft Lync, or for Cisco Unified Personal Communicator, enable detailed logging. We also recommend that users provide a description of the circumstances leading up to the error. For more detailed information, about how to run the PRT, or how to set the logging level, see the Troubleshooting section in the applicable Frequently Asked Questions document.

Log files and core dumps

By default, local logging on the thin client is disabled. You can use a script to enable logging for Cisco Virtualization Experience Client 6215 for troubleshooting purposes. You can also enable core dumping. You must have administrator privileges to run the script.

The following table lists and describes the options for the script. The script accepts two options (one for logging and one for core dumping).

For information about how to use the Diagnostic Log Viewer, see the Cisco Virtualization Experience Client 6215 Administration Guide available from:

http://preview.cisco.com/en/US/products/ps11976/prod_maintenance_guides_list.html

Table 2

Option
Description

-l on

Turn on logging for Cisco VXC 6215. This option creates the /etc/vxcclog.conf and /etc/virtualchannellog.conf files; and writes logs to the /var/log/cisco directory. The script also restarts Cisco VXC 6215 so the change takes effect immediately.

The log files for the Cisco VXC 6215 application are: /var/log/cisco/vxcc.log and VirtualChannelLib.log.

The log file for the Citrix Receiver is: /var/log/cisco/VirtualChannel.log.

This option also creates the device-managerConsole.log and device-managerError.log, after the next connection to the hosted virtual desktop (HVD). These two files are enabled by default, although logging is disabled by default.

-l off

Turn off logging for Cisco VXC 6215. This option deletes the /var/log/cisco directory and all the files in that directory, including /etc/vxcclog.conf and etc/virtualchannellog.conf.


Note You cannot run the script to turn off logging from within the /var/log/cisco directory.


The script also restarts Cisco VXC 6215 so the change takes effect immediately.

-c on

Turn on core dumping. This option adds a configuration line to /etc/sysctl.conf. The script also prompts you to restart the thin client for the changes to take effect.

Core dumping is a system wide policy; after you enable it, any process that crashes produces a core dump and saves it to /tmp. The file name format is: core_PROCESSNAME_TIMESTAMP.

The system generates core files when a process crashes.

The /tmp directory may contain multiple core files. The timestamp in the file name should assist with the identification of the core files generated around the time of the incident under investigation.

-c off

Turn off core dumping. This option removes the configuration line from /etc/sysctl.conf. The script also prompts you to restart the thin client for the changes to take effect.

Note If you turn off core dumping, the script deletes all core dumps from the /tmp directory, including core dumps not created by Cisco VXC 6215.

-h

Display the usage help.


Logging operations

Script example 1

vxcc -l off -c on

In this example, the script turns off logging and turns on core dumping.

Script example 2

vxcc -l on

In this example, the script turns on logging.

Audio issues

If a user experiences issues with audio (for example, the user has video for a call, but not audio) the camera may have become the active audio device. There are two ways to resolve this issue:

Resolution 1

1. Unplug the headset and then plug it back in.

2. Sign out and back in to Cisco UC Integration for Microsoft Lync or Cisco Unified Personal Communicator.

3. Alternately, you can stop and then start Cisco UC Integration for Microsoft Lync or Cisco Unified Personal Communicator.

If the audio issues persist, try Resolution 2.

Resolution 2

1. Restart the thin client without the camera and headset connected.

2. Plug in the camera.

3. Plug in the headset and wait a couple seconds.

4. Sign into Citrix.

No audio with the Plantronics Voyager Pro UC V2 headset

After a user plugs in the Plantronics Voyager Pro UC V2 headset and answers a call, the audio may not work. To resolve this issue, after answering an incoming call, press the Call button on the headset. Users need only do this for the first call after plugging in the device.

Get the version of Cisco Virtualization Experience Client 6215 installed on the thin client

1. Open a terminal window on the thin client

2. rpm -qi vxc

You can also use the versionInfo command.

Ensure that vxcc is running on the thin client

1. Open a terminal window on the thin client

2. ps -ef | grep -r vxcc

You should see the following lines:

/bin/bash /usr/bin/pidrun.sh vxcc /dev/null /dev/null

1

vxcc

grep vxcc

Ensure that credentials are passed down the virtual channel
to the thin client

1. Turn off logging to remove the vxcc_logs files.

vxcc -l off
