Some Nokia cell phones include a built in SIP client for making VoIP
calls. The SIP client is not an add-in software, but a completely integrated
solution for making VoIP calls. The quality of this SIP client is excellent, and it
can be used directly from the phone's contact list without starting up a third party
application.
There are three stages to setting up DUAL Talk SIP calling on your Nokia phone:
- Downloading a Nokia configuration application
- Defining the DUAL Talk SIP settings
- Creating a SIP Service

|
| Not all VoIP settings are available on the menu of this Nokia telephone.
Nokia have made an application available that adds the menu options necessary for
you to define your own SIP carriers on your telephone. Point your mobile browser to http://dualtalk.com/sip5.sis and
download and install the application. |
|
|
Creating the SIP settings
|
|
|
|
| Start the Net settings application on your menu at Settings
| Connectivity | Admin. settings. Select Advanced VoIP settings | SIP
settings. Use the Options key to select New SIP Profile | Use
default profile. Most of the settings on this page can be left at their default
values, but the following settings should be made:
- Optionally, set a Profile name. In this case, the name has been set to DUAL
Talk.
- Set an access point. This is very important, and tells your phone which internet
connection to use for SIP calls.
- Set Public user name to [DUAL Talk account number]@sip.dualtalk.com. So,
if your DUAL Talk account number is 100001, set this field to 100001@sip.dualtalk.com.
- Scroll down to Registrar server and select this entry. This will open a
new page, where the following settings should be made:
- Registrar server address = sip.dualtalk.com
- Realm = sip.dualtalk.com
- User name = [Your DUAL Talk account number]
- Password = [Your DUAL Talk password]
Press the Back key twice, and you should see a list of defined
SIP settings. DUAL Talk should be shown on the list as "Not registered",
because the registration will take place before the first call attempt.
|
|
|
| Press the Back key to return to the Advanced settings menu
and select VoIP services., which is usually above SIP settings. Click
on the Options key and select New Service and then DUAL Talk.
There is no need to activate the service at this point.
Return to the home screen. Your Nokia cellphone is now configured to
make SIP calls through DUAL Talk. |
|
|
| Having configured your Nokia mobile phone for VoIP calling through DUAL
Talk, you are ready to make your first call. We have a test facility that you can
reach by calling 123. To make a call, press 123 and then the Net call
key. If the configuration was correct, you should hear the message "This is the
Internet Telephone calling service. Please contact your service provider to activate
your account". As this is the first Nokia SIP call that you have made since you
switched on the telephone, you will be prompted to register with the internet telephone
service. Pressing the Yes key will cause the internet connection to be
established and registration with DUAL Talk to take place. This will take a few
seconds. After this, the call should connect.

Common questions about Nokia VoIP
|
|
|
|
My phone is not on the list of support Nokia mobiles. What
should I do?
If your phone is not listed, then it does not include a SIP client and integrated VoIP
is not available. VoIP calling may still be possible with these phones, and we
suggest you investigate Nimbuzz as
a possible solution, because Nimbuzz allows you to configure other SIP providers for
calling with their software.
Can SIP calls be made through 3G or GPRS?
We recommend making calls through WLAN (WiFi). 3G (UMTS) and GPRS may work, but
your experience will vary depending on the quality of the internet service provided by
telephone provider. Also, data sent through a 3G or GPRS connection may be
chargeable. All of the phones listed are capable of VoIP over 3G/GPRS except the
Nokia 6300i, Nokia 6260 Slide, Nokia C3-01 and Nokia X3-02.
Which codec does the Nokia SIP client support?
With DUAL Talk, the Nokia SIP client will make calls using the G.711 codec. This
provides the best quality, but can be bandwidth intensive. If you prefer, we can set
your account to use the lower bandwidth G.729 codec. Please contact our support team to have this feature set on your
account.
Can the Nokia phone be configured to always register with DUAL Talk?
Yes, you can set this on the SIP settings page. Change Registration
from When needed to Always on. You may find your batter draining
quicker with this option set.
Do I have to dial 00 for all calls, including calls to my own country?
No. You can set your own country code at My DUAL Talk. This can help to match
DUAL Talk with your contacts list format.
Can I set all calls to use DUAL Talk by default?
Usually, yes. Please refer to your Nokia user guide.
