Internet calls
Your Nokia E61i supports voice calls over the Internet
(Internet calls). With the Internet call service (network
service), you can make and receive calls over the Internet.
Internet calls can be made from places that have a
broadband connection and WLAN access, e.g. homes,
hotspots at airports, and cafes.
Note: The Internet Call service must be set up
on your Nokia E61i before you can make or
receive calls. In addition to an active WLAN
connection, you need an Internet call account
from a SIP VoIP service provider.
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.
The availability of the Internet call service may vary
according to your country or sales area.
Define the Internet call settings
If your Internet call service provider offers provisioning for
the SIP VoIP settings, it is suggested to use the
provisioning service instead of defining the settings
manually. For details, contact your service provider.
Before you can make Internet calls, you need to define the
Internet call settings. After you have defined the Internet
call settings with these instructions, your device logs in to
the Internet call service automatically when you select
Menu > Connect. > Internet tel..
To define the Internet call settings, do the following:
1Define a SIP profile.
2Define an Internet call profile.
3Select a preferred Internet call profile (optional).

establishing, select Cancel.
Select Options and from the following:
•Connect to service — to establish a connection to a
service, when there is an Internet call service and
suitable connection network available.
•Disconnect from serv. — to end the connection to the
Internet call service.
•Change service — to choose the Internet call service for
outgoing calls if the device is connected to more than
one service. This option is shown only if there is more
than one configured service available.
•Configure service — to configure new services.
This option is shown only if there are services that
have not been configured.
•Save network — to save the network settings to which
you are currently connected. The previously saved
networks are marked with a star icon on the list of
connection networks. This option is shown only if you
are connected to an unsaved WLAN network.

service using a hidden WLAN network.
•Refresh — to manually refresh the list of connection
networks. Use this option, if your WLAN network is not
shown on the list. The list is also refreshed
automatically every 15 seconds.
The available options may vary.
Your device can be connected only to one WLAN access
point at a time. If you use two or more Internet call
services, which use the same access point, your device may
be connected to multiple services at the same time. The
service used for outgoing Internet calls is shown in the
view, where the connection networks are listed, and can
be changed by selecting Change service.
After you have successfully connected to a service, you
can save the used WLAN network as a known access point.
Connect using a shortcut
You may have a shortcut for Internet tel. in the active
standby or you can add a shortcut if it is not available. By
using the shortcut, you can register manually if an
Internet call service and an access point are available. If
you are already connected to an Internet call service, the
device asks if you want to disconnect from the service.

Make Internet calls
If you set Internet call as the preferred call type and your
device is connected to an Internet call service, calls are
made as Internet calls as the default.
To set the preferred call type for outgoing calls, select
Menu > Connect. > Internet tel. > Options > Settings >
Preferred call type > Cellular or Internet call.
After you have connected to an Internet call service,
icon appears on the display in the standby mode,
indicating that you have an active WLAN connection and
that the device is registered with a SIP server so you can
make Internet calls.
You can make an Internet call from all applications where
you can make a regular voice call.
To make an Internet call in the standby mode, enter the
phone number or Internet address, and press the call key.
Note: To make an Internet call to an address
that does not start with a digit, press any
number key when the device is in the standby
mode; then press # to clear the display and to
switch the device from number mode to letter
mode. Write the address, and press the
call key.
You can also make an Internet call from Contacts and Log.

Network Address Translation
(NAT)
Nokia E61i supports STUN (Simple Traversal of UDP
Through NATs) servers for NAT (Network Address
Translation) traversal, for networks where you do not have
a public IP address. Even with STUN servers in use it is
possible that the connection will not work, as some types
of NATs still block the traffic.
The settings for NAT traversal can only be provisioned by
the service provider, for example over the air or via
download, but cannot be edited manually by the user.
Unlike the SIP settings and Internet call settings, the NAT
settings cannot be defined manually, and it is therefore
recommended to use provisioning offered by Internet call
service provider.
NAT
There are two types of network address translation.
The type often popularly called simply NAT (also named
Network Address Port Translation or NAPT) refers to
network address translation involving the mapping of port
numbers, allowing multiple machines to share a single IP
address. The other, technically simpler form - also called
NAT or basic NAT or static NAT - involves only address
translation, not port mapping. This requires an external IP
address for each simultaneous connection. Broadband
routers often use this feature to allow a designated
computer to accept all external connections even when
the router itself uses the only available external IP
address.
STUN
STUN (Simple Traversal of User Datagram Protocol (UDP)
Through Network Address Translators (NATs)) is a network
protocol allowing a client behind a NAT (or multiple NATs)
to find out its public address, the type of NAT it is behind
and the Internet side port associated by the NAT with a

particular local port. This information is used to set up
UDP communication between two hosts that are both
behind NAT routers.
STUN is a client-server protocol. Nokia E61i includes a
STUN client which will send a request to a STUN server.
The server then reports back to the STUN client the public
IP address of the NAT router, and the port opened by the
NAT to allow incoming traffic back in to the network.
The response also allows the STUN client to determine
what type of NAT is in use, as different types of NATs
handle incoming UDP packets differently.
Protocols like SIP use UDP packets for the transfer of
sound/video/text signaling traffic over the Internet.
As both endpoints are often behind NAT, a connection
cannot be set up in the traditional way. This is where
STUN is useful.
Emergency calls
Your device attempts emergency calls primarily over
cellular networks. If an emergency call using cellular
networks is not successful, 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, 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.
