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 two stages to setting up DUAL Talk SIP calling on your Nokia phone:
- Defining the DUAL Talk SIP settings
- Creating a SIP Profile
|
 |
 |
Creating the SIP settings
|
|
|
|
| Select the SIP settings area on your phone. Usually, this is
located under Tools | Settings | Connections | 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 Connection menu and
select Internet tel., which is usually below SIP settings. Click on
the Options key and select New Profile. A new profile may be
created immediately, but, if more than one SIP setting exists on your phone, then you will
be prompted to choose a SIP setting to associate with this new profile. In this
case, select the xxxxxx@sip.dualtalk.com setting. Change the Name
setting to DUAL Talk.
Press the Back key and 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 Options key.
From the menu, choose Internet call. On some phones, the selection
will be Call | Internet call. On phones with a qwerty keypad (for example,
the Nokia E71), you can force a SIP call by adding @ to the end of the number, in which
case, you should call 123@ followed by the green call button. 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.
You can also make calls from your contacts list by selecting the contact and pressing
the Options key. Then choose Call | Internet call.

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.
