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.
