Proxy server address
The SIP proxy is your VoIP provider's gateway server. Enter the IP address or the
(fully-qualified) DNS name of your SIP proxy server (maximum 74 characters).
Example: myprovider.com.
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 (fully-qualified) DNS name or the IP address of the registrar server
(maximum 74 characters).
The registrar is needed when the phone is registered. It assigns the public IP
address/port number that were used by the phone on registration to your SIP
address (Username@Domain). With most VoIP providers, the registrar server is
identical to the SIP server. Example: reg.myprovider.com.
Registration server port
Enter the communication port used on the registrar. Port 5060 is used in most
cases.
Registration refresh time
Enter the time intervals (in seconds) 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 car-
ried out for all activated VoIP connections.
The default is 180 seconds.
If you enter 0 seconds, the registration will not be repeated periodically.
Area: Network data for your service provider
Please note
If you have downloaded the general settings for your VoIP provider from the
Gigaset configuration server
preset with the data from the download (e.g., the settings for the STUN server
and outbound proxy).
If your phone is connected to a router with NAT (Network Address Translation) and/
or a firewall, you must select some settings in this area so that your phone can be
reached from the Internet (i.e., can be addressed).
Through NAT, the IP addresses of subscribers in the LAN are concealed behind the
public IP address of the router.
