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 there-
fore 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 Trans-
versal 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/firewall in
the router/gateway.
¤
Enter the required data for the STUN server or outbound proxy:
STUN enabled
Click on Yes if you want your phone to use STUN as soon as it is used on a router with asym-
metric NAT.
STUN Server Address
Enter the DNS name or the IP address of the STUN server on the Internet. If you have
selected Yes 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.
