The Gigaset.net connection is preconfigured in your phone. The Gigaset.net 

uses a STUN server as standard. In the sent data packets, Gigaset.net replaces 

the private IP address of your phone with its public IP address. 
If you operate your phone behind a router with symmetrical NAT, STUN cannot 

be used. Otherwise, when making Gigaset.net calls you will not be able to hear 

the caller. 
In this case, deactivate STUN for the Gigaset.net connection.

The voice quality for VoIP connections is mainly determined by the voice codec 

used for transferring the data and the available bandwidth of your DSL con-

nection. 
In the case of the voice codec, the voice data is digitalized (coded/decoded) and 

compressed. A "better" codec (better voice quality) means more data needs to 

be transferred, i.e. perfect voice data transfer requires a DSL connection with a 

larger bandwidth. 
The following voice codecs are supported by your phone:

Excellent voice quality. The broadband speech codec 

 works at the same 

bit rate as G.711 (64 kbit/s per speech connection) but with a higher sampling 

rate. This allows higher frequencies to be played back. The speech tone is there-

fore clearer and better than for the other codecs (High Definition Sound Per-

formance). 
Gigaset S67H, S68H and SL37H are examples of HDSP-compatible handsets. 

If you do not use your Gigaset.net connection for six weeks, it is automatically 

deactivated. You cannot be reached for calls from Gigaset.net. 
The connection is reactivated:

u

As soon as you start a search in the Gigaset.net directory (

) or 

u

Make a call via Gigaset.net, i.e. dial a number ending in #9 (two attempts 

may be necessary) or 

u

Activate the connection via the Web configurator as described above.
