Voice switch cause

Reason why a call had to be placed into half duplex mode in order to prevent echo. In half duplex mode, communication can travel in only one direction at a time, similar to the way users take turns when communicating with a walkie-talkie. Select one of the following:

• [All]
  
  
• None
  
  
• Bad timestamp
  
  
• Echo
  
  
• DNLP (dynamic nonlinear processor)
  
  
• Low complexity
  
  
• Bad device state
  
  
• Post-AEC echo (acoustic echo cancellation)
  
  

Echo cause

Reason why echo above the accepted level was detected in a call. (In telecommunications, echo is a reflection of sound, the same phenomenon you will hear if you yell down to the bottom of a well.) Select one of the following:

• [All]
  
  
• None
  
  
• Bad timestamp
  
  
• Post-AEC echo (acoustic echo cancellation)
  
  
• ANLP (adaptive nonlinear processor)
  
  
• DNLP (dynamic nonlinear processor)
  
  
• Microphone clipping
  
  

Call type

Indicates the type of call that was made. Select one of the following:

• [All]
  
  
• Client call
  
  
• PSTN call
  
  
• Conference call
  
  

Access type

Indicates whether the client was logged on to the internal network or the external network when the call was placed. Select one of the following:

• [All]
  
  
• Internal
  
  
• External
  
  

Network type

Indicates the type of network the client was connected to when the call was placed. Select one of the following:

• [All]
  
  
• Wired
  
  
• Wireless
  
  

VPN

Indicates whether an external client was using a virtual private network (VPN) connection when the call was placed. Select one of the following:

• [All]
  
  
• VPN
  
  
• Non-VPN
  
  

Device type

Indicates the type of device. Select one of the following:

• Capture device
  
  
• Render device
  
  
• Capture/Render device pair
  
  

Device name

Name of the capture or render device. You can enter the complete device name or any portion of the device name. For example, to find the device Microphone (Microsoft LifeCam VX-1000.), you can enter the complete device name as follows:

Microphone (Microsoft LifeCam VX-1000.)

Or, you can enter just a portion of the name. For example:

LifeCam

Note that the preceding filter returns any device that contains the string "LifeCam" anywhere in its name.

Capture device

Yes

Device (for example, a microphone or webcam) used for transmitting audio.

Render device

Yes

Device (for example, a headset or speakers) used for receiving audio.

Call volume

Yes

Total number of calls placed.

Poor call percentage

Yes

Percentage of calls that were classified as "poor." A poor call is any call which at least one of the measured metrics exceeded the allowed value (for example, a call that experienced excessive jitter).

Unique users

Yes

Unique users who used the device. If a user used the device 13 times he or she would count as one unique user, the same as a user who only used the device a single time.

Ratio of voice switch time

Yes

Percentage of the call that had to be conducted in half duplex mode in order to prevent echo. In half duplex mode, communication can travel in only one direction at a time, similar to the way users take turns when communicating with a walkie-talkie.

Ratio of microphone not functioning

Yes

Percentage of the call in which the capture device was not functioning at an acceptable level. A high values suggests that quality issues with the call were primarily due to the capture device not working as expected.

Ratio of speaker not functioning

Yes

Percentage of the call in which the render device was not functioning at an acceptable level. A high values suggests that quality issues with the call were primarily due to the render device not working as expected.

Calls with voice switch (%)

Yes

Percentage of the total calls which had to be placed into half duplex mode. In half duplex mode, communication can travel in only one direction at a time, similar to the way users take turns when communicating with a walkie-talkie.

Echo microphone in (%)

Yes

Percentage of echo that was present in the microphone. (In telecommunications, echo is a reflection of sound, the same phenomenon you will hear if you yell down to the bottom of a well.) Typically you will see low values for headsets or handsets, and higher values for speaker phones or stand-alone speakers.

Echo send (%)

Yes

Percentage of echo transmitted to other users.

Calls with echo (%)

Yes

Percentage of the total calls that had echo exceeding the acceptable level.
