I have found the solution with DBus

from terminal execute:

dbus-send --print-reply --type=method_call --dest=com.nokia.osso_addressbook /com/nokia/osso_addressbook com.nokia.osso_addressbook.mime_open string:'filename.vcf'

with QT:

QDBusInterface *ABook = new QDBusInterface("com.nokia.osso_addressbook", "/com/nokia/osso_addressbook", "com.nokia.osso_addressbook", dbus);

ABook->call("mime_open", file.fileName());


thanks
