Troubleshooting the Avaya 2050 IP Softphone
123
• Check that the mute button is disabled. If mute is enabled, the mute
button on the Call Control window appears red.
• If your server uses a Network Address Translation (NAT) device,
check for proper NAT configuration. One-way only audio problems
can occur when incorrect NAT configuration causes the
Avaya 2050 IP Softphone to attempt to connect to the wrong IP
address.
Broken or choppy speech
Broken or choppy speech can occur due to any of the following:
• Low level of audio buffering
• Windows transition effects
• Other running applications
Audio buffering
Use the Audio dialog box to adjust the level of buffering between your
audio hardware and the Avaya 2050 IP Softphone. For details, see
“Audio” on page 88 .
Use the audio Quality slider to increase or decrease the amount of delay.
Less delay speeds up buffering, but reduces audio quality. Higher
quality improves audio quality, but slows down buffering.
When experiencing choppy or broken speech, move the Audio Quality
slider toward Higher Quality .
Windows transition effects
The Windows operating system uses very high process and thread
priorities when performing low-level Windows operations, such as
minimizing and maximizing applications. This can cause brief breaks in
the Avaya 2050 IP Softphone audio streams.
To reduce the severity of these breaks, turn off the Windows transition
effects for menus and tool tips.
