The Echo cancellation option reduces audible echo for callers.
An echo will be heard if a speaker and a microphone or a badly

calls via the receiver as soon as the caller speaks.

The Local echo option is only available if your sound card sup-
ports 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 tele-
phone. This option is only recommended if you are using a head-
set.
