VoIP (Voice over Internet Protocol) technology is a set
of protocols that facilitate phone calls over an IP
network, such as the Internet. VoIP phone calls can be
established between computers, between mobile
phones, and between a VoIP device and a traditional
telephone. To make or receive a VoIP call, your device
must be within WLAN coverage, for example.
You can make an Internet call from all applications
where you can create a regular voice call.
You must define VoIP settings in Menu > Tools >
Settings > Call and Connection. Contact your service
provider for more information and correct settings.
Preferred profile
Select Menu > Connect. > Inter. tel. to change settings.
To select the profile that is used by default when you
make Internet calls, select Preferred profile and press
the joystick. Scroll to the desired profile and press the
joystick.
Registering profiles
To change the registration of your Internet telephone
profiles, scroll to the profile that you want to register
or unregister and press the joystick. Press the joystick
again to select Registered or Not registered.
To save your settings, select Back.
