The service path is always the same, org.ofono. What you're referring to is the dbus interface name.

No, the API has been specifically designed to separate CDMA and GSM details. There are too many differences in the two systems and their respective capabilities to mash them together.

The basics are the same, sure. However, once you get into the details of three way calls, call waiting, multiparty calls, etc the logic and API becomes vastly different. Not to mention the various differences between carriers and their specific extensions. Bottom line is, compared to insanity of GSM/UMTS, CDMA is even more of a mess and the API needs to evolve on its own. In the future, if it makes sense to unify them, then we can do so. That time is not now. > Regards, -Denis _______________________________________________ ofono mailing list ofono(a)ofono.org https://lists.ofono.org/mailman/listinfo/ofono
