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 along 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:

Select Yes if you want your phone to use STUN as soon as it is used on a router with asymmetric 
NAT.

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.

Enter the number of the communication port on the STUN server. 

 

The default port is 3478.

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 pro-
vider for the STUN refresh time if necessary. Default setting: 240 seconds.

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. Default setting: 20 seconds.

Specify when the outbound proxy should be used.

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.

Enter the DNS name or the IP address of your provider's outbound proxy. With many providers, 
the outbound proxy is identical to the SIP proxy.

Enter the number of the communication port used by the outbound proxy. The default port is 
5060.

¤

If your provider provides exteded PBX services enter the Server address, User name and the 
Authenticaton password.

¤

To change the password enter a new password an click on OK.

All signalling and voice data sent by the phone is sent to the outbound proxy.

The outbound proxy is not used.
