•
Check that your system administrator has programmed the handsfree option on the
communications 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 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
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.
To turn off the Windows transition effects
Select Start > Control Panel > Display
1
Select the Effects tab, (or, in Windows XP, the Effects button on the Appearance tab).
2
Clear Use transition effects for menus and tool tips.

Other applications
Other applications running on your computer, especially CPU-intensive applications or
applications that intercept or delay packets (such as firewalls), can cause broken audio.
Multiple Ethernet interfaces on a single PC can sometimes conflict with each other. For example,
the Avaya 2050 IP Softphone sometimes exhibits intermittent breaks in audio when using docked
notebooks that have a Xircom RealPort Cardbus Ethernet 10/100+Modem 56 PC Card (PCMCIA)
inserted. In the specific case of this PC card, the problem relates to a version of the Xircom driver.
This driver takes CPU cycles even when it is not active and this, in turn, causes Avaya 2050 IP
Softphone audio to become choppy.
