The Echo cancellation option reduces audible echo for callers. An echo will be
heard if a speaker and a microphone or a badly suppressed headset is used. If this
option is activated, the microphone is suppressed, or for hands-free calls it is
muted during calls via the receiver as soon as the caller speaks.
The Local echo option is only available if your sound card supports the direct
output of microphone data to the speaker. This means that speech is played back
without delay in suppressed form on your speaker, in the same way that it is on
your telephone. This option is only recommended if you are using a headset.
The Use DirectSound option allows multiple applications to output acoustic
signals simultaneously. This means that you can use the OpenPhone IPC while
playing music data, for example. Deactivate this option if you experience
problems with the input and output of audio data.

Select the sound card for the audio input and
output. The selection is necessary if multiple
sound cards or sound-card drivers are
installed. The settings for input and output
must refer to the same device. When using
DirectSound too, the same device must be
selected for input and for output in the
system's sound and multimedia settings.
You can also specify which connected device
emits the ringing tones, e.g. a connected
headset or a speaker connected to the sound
card.
