Net calls
Your device supports voice calls over the Internet (Internet calls). Your device attempts emergency calls primarily over cellular
networks. If an emergency call using cellular networks is not successful, then your device attempts an emergency call through
your Internet call provider. Due to the established nature of cellular telephony, you should use cellular networks for emergency
calls, if possible. If you have cellular network coverage available, please make sure that your cellular phone is switched on and
ready to make calls before you attempt an emergency call. The capability for an emergency call using Internet telephony depends
on the availability of a WLAN network and your Internet call provider's implementation of emergency call capabilities. Contact
your Internet call provider to check the Internet telephony emergency call capability.
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.
Before you can make net calls, you need to create a net telephone profile. When the profile is ready, you can make a net call
from all applications where you can create a regular voice call. To make a net call to an address that does not start with a digit,
press any number key when the device is in standby mode, then press # for a few seconds to clear the display and to switch
the device from number mode to letter mode. Write the address and press the call key.
