Web configurator – configuring the phone on a PC
STUN Refresh Time [sec]
Enter the time intervals (seconds) at which the phone should repeat the registration with
the STUN server. The repeat is required so that the phone's entry 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 if necessary. The default setting is 30 seconds.
NAT Refresh Time [sec]
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 shorter than the NAT session timeout. As
a rule you should not change the default value for the NAT update. The default setting is
20 seconds.
Outbound Proxy Mode
Specify when the outbound proxy should be used.
Always
Automatically
Never
If you leave the Outbound Server Address field empty, the phone does not respond to the
selected mode and operates as if Never were selected.
Outbound Server Address
Enter the DNS name or the IP address of your provider's outbound proxy. With many pro-
viders, the outbound proxy is identical to the SIP proxy.
Outbound Proxy Port
Enter the number of the communication port used by the outbound proxy. The default
port is 5060.
Automatic Negotiation of DTMF Transmission
DTMF signalling is required, for example, for querying and controlling certain network
mailboxes via digit codes or for remote operation of the local voice mail. Select whether
the setting should be made automatically. If you select No, you must determine the set-
ting for the DTMF transfer yourself.

All signalling and voice data sent by the phone is sent to the outbound
proxy.
Data sent by the phone is only sent to the outbound proxy when the
phone is connected to a router with symmetric NAT or a blocking fire-
wall. If the phone is behind an asymmetric NAT, the STUN server is used.
If you have set STUN enabled to No, or if you have not entered a STUN
server, the outbound proxy will be used in all cases.
The outbound proxy is not used.
