STUN server
Enter the (fully-qualified) DNS name or
the IP address of the STUN server on
the Internet.
If you selected
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.
Outbound proxy port
Enter the number of the communica-
tion port used by the outbound proxy.
The default port is 5060.

rity measures. You can subsequently con-
tinue the entry and make changes if nec-
essary.
