Troubleshooting the IP Softphone 2050

Audio problems
Basic audio operation
To verify the physical connection of the USB adapter and headset, as well
as proper Windows audio configuration:
1. Record an audio message.
2. Play the message back using the USB headset.
One-way audio
If you experience problems with one-way only audio:
• Check that your system administrator has programmed the handsfree
option on the communication server.
• 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
IP Softphone 2050 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 IP Softphone 2050. For details, see “Audio” on
page 69.
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.
