Managing VoIP profiles
S60 3rd Edition SDKs do not provide any APIs for adding, editing, or removing VoIP profile settings.
There are no APIs for VoIP profile management. VoIP profiles can be manually edited via the Settings application (Settings -> Connection -> Internet tel. settings).
Also, VoIP settings can be configured with OMA Client Provisioning. For more information, see the following Nokia Developer documents:
