Problems during a call

I cannot hear the party I am calling.

Check the following:
The phone’s microphone of the party you are calling is set to Mute.
The volume level of the speaker of the phone device that you are using

(handset, headset, or speaker) is set too low to be heard. Increase the

volume level by pressing the Playback volume + button on the

keypad. Be aware that the volume settings of the handset, headset,

and speaker are independent of one another. Changing the volume

setting of one device does not change the volume setting of the other

two devices.

Change the device that you are using (from handset to headset or

speakerphone, or from headset to handset or speakerphone, or from

speakerphone to handset or headset).

The audio-speaker device settings in Microsoft Office Communicator

or the Windows operating system might have to be adjusted. If this is

the case, change these settings only when you are not in a call.

If you still cannot hear the other party, refer to

Phone as an Audio Device

I hear audio glitches or drop-outs.

Check the following:
Noise from the environment of the party you are calling, such as

typing strokes or writing on paper, may be coming through the

remote phone's microphone. Ask that the microphone be moved from

the source of the sound.

Wireless connection to the network may be causing audio noise. If the

computer accesses the network through a wireless connection,

temporarily turn OFF the wireless connection. Then, connect to the

network through a network cable.

Other programs running on the computer may be using network or

hardware bandwidth. Check the Windows Task Manager. Exit any

open resource-intensive programs that are currently not required.
