There are various ways of configuring a VoIP connection:
u
Some providers support auto configuration with an auto configuration code. In
this case, you merely have to start the configuration assistant (Start Configura-
tion Assistant button). It prompts you to enter the configuration code. All the
required VoIP data is then downloaded into the areas specified above. The con-
figuration is complete.
u
Most providers supply provider profiles with the general provider data on the
configuration server. You can use the configuration assistant to load them to
your phone. To do this, click on the Start Configuration Assistant button. The
assistant prompts you to select your country and the provider. It then loads the
provider profile data to the areas General Data of your Service Provider and
Network Data of your Service Provider.
You then have to transfer your personal account data to the assistant.
In exceptional cases, you also have to adjust the settings in the Network Data of
your Service Provider area to suit the settings for your router:
– If you cannot hear the caller on an outgoing call, you may have to switch
between outbound proxy server mode and STUN use. In the sent data
packets, the STUN or outbound server replaces the private IP address of your
phone with its public IP address. If you operate your phone behind a router
with symmetric NAT, STUN cannot be used.
– If you are sometimes unavailable for incoming calls, you may have to adjust
the value in NAT refresh time:
If you have not activated port forwarding or set up a DMZ on the router for
the phone, an entry in the routing table for the NAT (in the router) is required
to make the phone available. The phone must confirm this entry in the rout-
ing table at certain intervals (NAT refresh time) so that the entry stays in the
routing table.
u
There is no provider profile for your provider.
If this is the case, you must change the settings in the Personal Provider Data,
General Data of your Service Provider and Network Data of your Service Pro-
vider areas yourself. Your VoIP provider will supply you with this data.
