Proxy Server Port
Enter the number of the communication port that the SIP proxy uses to send and
receive signalling data (SIP port). Port 5060 is used by most VoIP providers.
Registration Server
Enter the IP address or the DNS name of your registrar server. The registrar is needed
when the phone is registered. It assigns your SIP address (username@domain) to the
public IP address/port number your phone uses to log in. With most VoIP providers,
the registrar server is identical to the SIP server.
Example: reg.myprovider.de.
Registration Server Port
Enter the communication port used on the registrar. Port 5060 is used in most cases.
Registration Refresh Time [sec]
Enter the time intervals at which the phone should repeat the registration with the
VoIP server (SIP proxy) (a request will be sent to establish a session). The repeat is
required so that the phone's entry in the tables of the SIP proxy is retained and the
phone can therefore be reached. The repeat will be carried out for all activated VoIP
phone numbers. The default is 120 seconds.
If you enter 0 seconds, the registration will not be repeated periodically.

Network provider data
The phone needs to know its public address in order to receive caller voice data.
The SIP protocol recognises the following options:
u The phone requests the public address from a STUN server on the Internet (Simple
Transversal of UDP over NAT). STUN can only be used with asymmetric NATs and non-
blocking firewalls.
u The phone does not direct the connection request to the SIP proxy but to an outbound
proxy on the Internet that supplies the data packets with the public address.
The STUN server and outbound proxy are used alternately to work around the NAT/fire-
wall in the router/gateway.
¤ Enter the required data for the STUN server or outbound proxy:
STUN enabled
Click on Ye s if you want your phone to use STUN as soon as it is used on a router with
asymmetric NAT.
STUN Server Address
Enter the DNS name or the IP address of the STUN server on the Internet. If you have
selected Ye s in the STUN enabled field, then you must complete this field.
STUN Server Port
Enter the number of the communication port on the STUN server.
The default port is 3478.
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.
