Microphone sensitivity is reduced – consequence:
In order for the called station to hear the speaker properly, the distance to the microphone must be
decreased or the speaker must speak louder.
Echo Suppression is increased – consequence:
The more the “Echo Suppression”-level is increased, the more the conversation feels as if switched
with a “speech balance” (like switched duplex/half duplex).
This “speech balance” takes control of the conversation direction and switches through the louder
side of the conversation and reduces the volume of the quieter side.
Unique Feature of the SIP Series
Serverless Operation
The following section gives an overview of the required basic configuration of a SIP station as well as
a SIP telephone, at serverless operation.
As example a Snom®telephone is used.
A detailed description of the Snom®web interface won´t be found in this document, as on the basis of
the following example solely the
basic know-how
for the configuration of a serverless operation bet-
ween two SIP devices, shall be communicated.

A
SPEECH BALANCE
?
A “speech balance” is used in a “half duplex” conversation.
Because the stations of the SIP Series are “full duplex” capable, the speech balance is not active (ex-
works). Only when a special configuration (see
above
) is carried out, the conversation is controlled by a
similar behaviour.
For a clearer understanding please read the description of the two conversation modes:
H
ALF
D
UPLEX
(
SPEECH
BALANCED
):
The conversation direction is controlled by a “speech balance”. Therefore it is possible to talk and listen
without pressing a button. However only the louder side is switched through.
F
ULL
D
UPLEX
:
The conversation is permanently switched through in both directions. Therefore both conversation part-
ners can simultaneously speak and listen (=natural communication).
The great advantage of the SIP Series compared to other products is, that the above-mentioned
behaviour can be adapted to the requirements on site and therefore provide the greatest possible
conversation quality.
