STUN server
Enter the (fully-qualified) DNS name or 
the IP address of the STUN server on 
the Internet. 
If you selected the option 
Yes
 in the 
STUN enabled
 field, you must enter a 
STUN server
 here. 
STUN port
Enter the number of the communica-
tion port on the STUN server. The 
default port is 3478. 
STUN refresh time
Enter the time intervals at which the 
phone should repeat the registration 
with the STUN server. The repeat is 
required so that the entry of the phone 
in the tables of the STUN server is 
retained. The repeat will be carried out 
for all activated VoIP phone numbers. 
Ask your VoIP provider for the 
STUN refresh time
.
The default is 240 seconds. 
If you enter 0 seconds, the registration 
will not be repeated periodically. 
NAT refresh time
Specify the intervals at which you want 
the phone to update its entry in the 
NAT routing table. Specify an interval in 
seconds that is a little smaller than the 
NAT session timeout. 
As a rule you should not change the 
preconfigured value for the 
NAT refresh 
time
Outbound proxy mode
Specify when the outbound proxy 
should be used.
Always
 
All signalling and voice data sent by the 
phone is sent to the outbound proxy. 
Auto
 
Data sent by the phone is only sent to 
the outbound proxy when the phone is 
connected to a router with symmetric 
NAT or blocking firewall. If the phone is 
behind an asymmetric NAT, the STUN 
server is used. 
If you have set 
STUN enabled
 = 
No
 or 
have not entered a STUN server, the 
outbound proxy is always used. 
Never
 
The outbound proxy is not used. 
If you do not make an entry in the 
Out-
bound proxy
 field, the phone behaves 
independently of the selected mode, as 
with 
Never
Outbound proxy
Enter the (fully qualified) DNS name or 
the IP address of your provider's out-
bound proxy.

tion port used by the outbound proxy.
The default port is 5060.
