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 in standby
mode to an address that does not start with a digit,
press any number key, 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. If you have the fold open, and you
have created a net telephone profile, write the address
and press the call key.
You must define session initiation protocols (SIP)
