On some models (e.g. N95) certain VoIP settings are hidden by default. You will need Nokia's new VoIP SIP application to adjust them.
With this application you can create new VoIP profiles and modify the existing ones, create and modify VoIP parameters and NAT/Firewall traversal settings, that are normally not visible on the device UI (e.g. codec settings and SIP domain-specific NAT/FW settings).
It's also possible to save all the VoIP profile settings to a text file. It also enables VoIP over WCDMA which means you can make VoIP call over 3G Internet connection.
You can download the latest version of SIP VOIP settings from Nokia site
For better voice quality or in order to be able to make VoIP calls over 3G internet connection you need to use Nokia SIP VoIP Application you installed.
Go to Applications on your phone and click on "SIP VoIP Settings" application. Choose VoIP services/VoIPVoIP (or the name of your VoIPVoIP account Internet profile.) Click on "Profile Settings" and find "Allow VoIP over WCDMA" option and change it to "ON". This change allows VoIP over 3G connection on Nokia phones.
For better voice quality go to Codecs and delete all codecs except G729. There should be only G729 codec left under codecs settings.
